View Full Version : how far have you gotten on your robot?
my team...well...um... we opened the box and umm... we put together the kitbot sort of and umm... :confused: i dont know what else we did
how far have other teams gotten?
if yo didnt use the kitbot what did you use? i mean there is the costs and the design and the kitbot is simple. please explain ow you can make something other that a kitbot with the KOP

we only have some prototypes made from cardboard, we can stop the camera from having fits, and its so freaking cold in our shop! but the 3ds max team (which only consist of me and two other non-dedicated dudes :( ) is doing well. I just finishing lip synch today and i only had one aneurysms so far :D .

One week in, and after strategizing the heck out of the game, 1293 has together our Kitbot frame and transmissions, with the gear tooth sensors mounted as well.
This week, the aim is to get Chomp ready for wiring.
(Yes, that would also be the first public mention of our 2006 robot's name.)

You can purchase Alum stock from many sources and make a frame that is lighter and custom to your application. It really is not that hard.
good point.
unfortunutely we arent able to get mor alum so we are stuck using kitbot.
we are still working on trying to make the motors work and i just found out that wheels cant be chemically treater for traction.
my school has problems with their robot
which brings up another question: have you had problems with your robot/prototype? i mean something like blowing up or smoking. our motors started to smoke

The chassis design is pretty much complete. The environmental manipulators have gone through concept and are going into design.
We're far behind schedule, but doing very well compared to last year... The design deadline has been pushed back 4 days.
We also had time to play with some proof-of-concept prototypes and looked at a bunch of commercial ball throwing devices.
i remember the vex robots last year. my schools vex robot blew up and part of the team had scratches and burns.

Wow! tell me in detail how you got that to happen!
We have hardly even finished the chassis of the kitbot, but that's because we took a week off for exams.
Wow! tell me in detail how you got that to happen!
aactually it has almost happened before at home. the motors were accidentally left running and the thing heated up so much it started to smoke and burn.
at school it was all encased with no holes so the case exploded with the rest of that side.
strange things sometimes happen but for once this wasnt my fault
we just finished exams. we had to work through them
anyone else had things blow up or burn?
as for the motors on the kitbot smoking the real problem was because there was a gear stuck.
we now have it working again and it is fine

First thing is was the robot moving. If the robot was not moving then most likely your motors were made to run opposite of each of each other. Which could cause them to blow up since they would be fighting each other.
Our drivetreain design deadline is wednesday but I hear that we will be done by tomorrow and order parts by tomorrow and starting builing the drivetrain by wednesday.

actually our robot was upside down and we were staring at it dumbfounded.
the motor was plugged in but the gear that it was attached to was stuck
and during all this i thought: dont those look like the cookies i put in the oven before school...the oven is still on...oh no!!!

I watched a teammate last year shatter a Dremel bit and it literally threw shrapnel that bounced off his safety glasses...needless to say he held onto his goggles a little tighter after that encounter...
68 has a few prototypes working. We're still testing different ideas, though. Hopefully by the end of this week or next we will have settled on a design.
And no, we're not using the kitbot.

as far as that goes i have a couple of questions that is probably cause im a rookie.
1. What is a dremel bit?
2. how do they shatter?
3. if it shattered why did it "throw" shrapnel? it should have dropped.
4. why did it only hit his goggles?

A dremel bit is a bit for a small tool that spins at extremely high RPM. Good for grinding, cutting, etc.
http://images.google.com/images?q=tbn:icCuzDrZi3yVqM:www.canterbury-j-class.org.nz/images/dremel%2520mototool.jpg
Now, when a small, hardened tool breaks for some reason, it still contains a lot of energy. When it breaks, it shatters, and pieces, with lots of rotational energy, fly outwards, kind of like a sharp explosion. Little bits of shrapnel. When you use a dremel, you often end up putting your face quite close to the work, so when a bit shatters, it sprays stuff all over your face, including you safety glasses. I'm sure they had lots of little cuts too, but in comparison to what could have been lost, its very minor.

hmmm dremel looks sort of like a recipricoal saw.
anyway that is a very cool mishap even better than the picture of a whole bunch of high school students looking at a burning motor and not knowing what to do.

We have finished designing, and have been prototyping for a few days now. We just started to CAD everything, and work on the drive system.

Team 949 has gone through our concepts and we are now going through the designing period.
We are planning to build a prototype launcher and the target tomorrow and by next sunday we should have everything autocadded and ready for building..
Maybe we should build the kop bot.. hmm.. :rolleyes: other than that we haven't done anything else
Sgraff_SRHS06
15-01-2006, 22:27
We've also finished designing. We are just now in the final stages of prototyping and putting the finishing touches on our designs. Tomorrow we are going shopping for a good portion of the additional parts we need.
As programmer, I have no say in all of this, but I can make special interest advocacies. We finally got our Gyroscopes and our rights to the CMU Camera and the Accelerometer. The programmers, including myself, are currently writing pseudocode.
But we have made much more progress in our design than any of our teams in the past, outside of our rookie year.
-------------------------------------------------------------------------
As for kitbots, we are using the kit, but we are not staying inside it. This may be the first year in which we don't use the kit wheels, though. Our drive team wants "tricks" (trick wheels) and "grips" (grip wheels). After their experiments with Deeper Thought, the decided that the kit wheels were not going to be sufficient for climbing up the hill. So, I'm not sure if the kit wheels will hold. However, the chassis will be from the kit and we'll do better weight management (so we actually have a good frame).
Nuttyman54
15-01-2006, 22:37
We've got the design figured out and are tweaking a few dimensions. some of the team is building a test launcher and a goal, and we've got the Kitbot build (but not running) as a test bed for the sensors.
Alex Pelan
15-01-2006, 23:38
The short answer: "Not nearly far enough."
We have tested some prototypes with varying levels of success and have started some design work. We haven't put the kitbot from '06 together yet because of some offseason work we have been doing involving a kitbot that we had already put together.
Rick TYler
15-01-2006, 23:50
We didn't like how the first one turned out, so we are buildiing a second 'bot. Aw, just kidding. The chassis team is done with their design and they are ordering parts. The game system team is having the prototype shoot-off on Tuesday, and will order parts this week. The programming/controls team is working on driver selection, functional control design, and testing the camera and other sensors. The electrical/pneumatic team is playing cards and waiting. The PR team is supposed to deliver final designs on Friday for our t-shirts, driving suits, helmets, buttons, banners, and the animation file for our blimp.
One week in, we are four weeks behind. Life's like that. From Shakespeare in Love:
Philip Henslowe: Mr. Fennyman, allow me to explain about the theatre business. The natural condition is one of insurmountable obstacles on the road to imminent disaster.
Hugh Fennyman: So what do we do?
Philip Henslowe: Nothing. Strangely enough, it all turns out well.
Hugh Fennyman: How?
Philip Henslowe: I don't know. It's a mystery.
Replace "theatre" with "robotics" and you begin to understand...

We are using the kitbot frame with minor modifications, and have that all designed. Our arm* mechanism team has also created a shooter prototype. It seems to work well, so now we are tweaking it and finding the best configuration, making a final model, and moving on to the next challenge.
*I've been guilty of calling it the "arm" team accidentally more than once, and been ridiculed. My team also made fun of me for calling it that on Chief Delphi once as well, so here I am, making public amends to the community at large. :rolleyes:

Motors smoke probably because you burned them out by not gearing them well. There are a lot of other possibilities as to what went wrong. We could help you figure out what went wrong if you told us more about what you were trying to do.
Since the KOP came with a kit, we figure, someone has done the work for us. We'll try it their way.
We try not to build our own designs too early so that we don't limit our potential designs. We're in a brainstorming/designing/prototyping week. I guess we'll start finalizing in two more weeks. We hold off on 7-day work weeks until later in the build season. And of course, all weeks are paperwork weeks. Don't forget to go through the manual and get all of the little tasks done in time.

actually our robot was upside down and we were staring at it dumbfounded.
the motor was plugged in but the gear that it was attached to was stuck
and during all this i thought: dont those look like the cookies i put in the oven before school...the oven is still on...oh no!!!
aha! OK here's what went wrong. If the gear that the motor's output shaft was attached to was stuck, the motor was doing only what it knows how to do; it wants to move. It will keep forcing its way, drawing more current, trying to get its output shaft to move. If it's locked up, eventually the motor burns itself on the inside.
This is why we gear motors down. If you attach the motor directly to the wheel's axle, it doesn't have enough initial acceleration to go from zero to its max rpm, which is what it's trying to do. You know we solve this problem by putting a gear with fewer teeth on the motor, then a bigger gear on the wheel, and you get a ratio. The motor has to rotate several times before the one on the wheel makes it all the way around, but it's actually a good thing because it prevents it from locking up. The motor gets to move right away, so it's happy.
The worst thing that can happen is the motor is trying to move but can't, and then it keeps trying until it burns out. In the future, make sure the motor is free to move before you turn it on, and be ready to turn it off right away if something doesn't seem right.
A lot of other things could go wrong. You said you were using the kit, so I hope you were using the correct motor. It's the regular CIM motor, not the larger ones; part numbers FP801-005 vs FP801-001.
When motors are gone, they're gone. Spare parts are in 5.4.5 of the manual (you feel kind of crazy when you have a copy of the manual on your bed) the URL for the IFI store is http://www.ifirobotics.com/0-index.htm and I don't know how long it'll take for them to get there, so hurry.
I hope some of the things covered in this post were already familiar to you.
If you need more help, CD is the right place! Good luck! :)

We have made a prototype shooter (including some CNCed parts) that will send the ball 60 feet! :ahh: The accuracy still needs a little working on, but it was hard to know on a windy day and outdoor testing space.
The gearbox design is almost done. CIM motors have been ordered. The wheels and frame construction has been decided. Frame design is starting. Wheels, gears, bearings, sprockets, and chain will be ordered on Wednesday.
The ball manipulation group is still working on conceptual pickup, conveyance, and feeding technique and volume allocation.
Overall, I'd say we're slightly ahead with the drivetrain and pretty much on track with the ball manipulation.
well weve gotten the kit frame and gearboxes build and mounted. weve got our bin fully designed and 75% done. and our cannon . .well its in that weird period where we know what it needs to look like and hows its going to mount and how its going to work, but not drawn out. so for a weeks worth of work I would say were ahead of the game.
We are now done with exams (we did work through them), but we are behind our schedule. Chassis building is in progress, one prototype tested, and the camera's getting coded while someone works on a scale model of the field. There are parts to be ordered and the website team is still brainstorming ideas.
Kim Masi
16-01-2006, 12:37
we put together the kitbot to house some of our prototype ball shooters, but we're not using it as our base. we're using box aluminum:)
the prototypes continue to develop, but we're having a lot of math errors in calculations. What does everyone think the perfect ball shooter will contain?
1 wheel? 2 wheels? how hard will it be to load?
we've had 2 tested prototypes so far with barely any success. But atleast we're learning. Right now, we're working on 2 more that will hopefully produce better results.
Our camera team continues to develop as they decode and find the target. We're really lucky for all our team did last year with the camera, so this year, the improvement on the vision system is helping us tremendously.
But Pelan, i am in agreement. Not far enough. Our mentor's goal is to have the robot finished in 3 weeks from today. Idk how that will work out, but we're trying ;)
so for most people the kitbot was not used and was discarded for custom designs. do the custom designs hit the maximums?
i know that the kitbot exceeds them. we had to cut the size down for ours.

16-01-2006, 14:21
we have the base done with two speed. we have the prototype shooter done and working very well. our 10 ball magazine done ready to go. only one thing left couple of front roller and a basket to hold them in. we figure by next Friday everything done and then getting a lot of drive and play time. this is where we find out what needs to be improved. (waiting for Fabric and pool noodles to come in to finish the bumpers)
We will have about 3 weeks of stick time. plenty of time to be ready.
my team has got the kit chasis nearly running and we have the basics of our design down and are in the process of tweaking it. farther along than I had dared to hope.
:D :yikes:
hmm making it in 2 parts is a good idea.
when we finish it it will probably be right before the deadline.
with ours the balls will have a conveyer belt carry them up and then a pneumatic shooter shoot them out. is this a good idea?
yay!!! this is my 50th post

We are building a life size field and training n00bs, while the veterans and some n00bs are working on the design.
i made the entire field in solidworks and our team leader made the platform out of plywood. we found that the kitbot barely makes it up the ramp without bottoming out

Our team prototypes everything first. So as of now it's all in cardboard and PVC. There are some details that need to be figured out with the design before we can put the kit bot chassis together. But we're basically on schedule and I'd say further along than last year so that's good. woot

We finished the kitbot chassis, we tossed on a couple of gears, and 2 CIM motors from last year, to set up 4 wheel drive. We did some testing, and we got it to push several cinder blocks, but the kitbot wheel slip way too much. We are searching for new wheels. Our camera is shy. It will look at the target, then stare at the ground. For our launcher, we have doodles and equations...
We are using the kit gearboxes, not using any other parts of the kitbot though.
Our progress:
Drivetrain design completed, Parts have been ordered and should be done by friday or saturday.
Payload concept is pretty much done, hasnt been designed in detail yet though.
Programmers having fun with the camera i think.
Field is partialy completed.

We have design ideas, but we've had lots of fun shooting poofs at people with our prototype :rolleyes: What's even funnier is that our advisor is encouraging us to shoot balls at each other! Now that I've gotten way off topic... The animation team has their concept and have started animating, we haven't assembled the vision target, but that's ok because we haven't even assembled the camera yet either. I love my team and our pro-procrastination style :D

We're done :shifty eyes:.
Our prototype chassis should be completed tonight and I hope to finish milling the competition-legal chassis parts by tomorrow night. I'm a bit behind because a dumb error on my part shorted out the CNC machine and it took some time for our electrically inclined people to track down the three fried voltage rectifiers and replace them.
The manipulator design is about 75% complete, I'd say, disregarding the less-important shooting mechanism. The easiest parts are finished -- namely the superstructure -- and it's awaiting motor mounts, belting, pulleys, chain and sprockets. We will likely need to redesign our hopper as well so as to better mate it to this new manipulator.
I flip-flop back and forth between thinking that we're on or ahead of schedule and chastizing myself for working so slowly on finalizing a design.

Well, our team has ordered most of the parts we need and plan to order the rest by wednseday. We have a shooter, a archimedes (sp?) screw, a conveyor belt and ball collector prototyped. We're using part of the kitbot chasis too. We need a few belts to get in before we do the drivetrain and we need to get some alum stock for the rest of the chasis, but otherwise, I'd say we are about on schedule.

For now, we are waiting for the oh so great Fed-Ex to deliver tons of goodies from McMaster Carr.
The transmission designs are complete, and will start to be machined tomorrow. (Note: All New England teams... run and hide ;) )
Whatever is putting the power to the floor is being machined this week.
Whatever is helping us score points has been loosely designed, and will be finalized and manufactured in the upcoming week and a half.
Programming and driver practice is expected to take >3 weeks.

Either that, or someone hasn't heard of "Haste makes waste" and isn't going to have a winning robot. I'm willing to bet that most of these teams are using Kitbot as their drivebase.
We are still in basic design, but we have one component made: the flag holder, minus endcap. We are also prototyping like anything this week.

We have our camera assembled but so far that's it. I'm looking at starting our electrical system soon though.
For programming, we managed to get our camera to move some before our laptop yelled at us and stopped cooperating. We also figured out what sensors we needed and laid out what we think would be a good control board, it will be changed though.
Mechanical is building the chassis and transmissions from the kit (with modifications of course), and deciding what parts need to be bought.
Everything else is prototypes and drawings though.

Well at the end of the first week our team has succesfully built a chassis that will go over the ramp. Still keeping our low center of gravity we are using a chasis similiar to KOP chassis and a tranny similiar to that of the KOP or if worst comes to worst the KOP tranny is what we will use. We have succesfully mad a ball collection device that picks up balls rather quick. And are shooter is nice we can shoot and have made baskets into a 27" hola hoop. and that was at about 30 feet away. So at the beginning of the second week we are beginning the techinical design and Fabrication. And also we have just found out that we lost one of our sponsors yesturday so we are going to be even better then we have been in the past, we think they were holding us back after the dissapointing last year. Wee have enough talent to design the robot plus we have aa the parts from the kit and previous year. So my prediction for how we are doing is better then we have in the past. :cool:

One week in, and after strategizing the heck out of the game, 1293 has together our Kitbot frame and transmissions, with the gear tooth sensors mounted as well.
This week, the aim is to get Chomp ready for wiring.
(Yes, that would also be the first public mention of our 2006 robot's name.)
dang... we have already got our launch systems going.
bam! 12 feet per second. this launcher is pretty awesome. and EXTREMELY accurate (spray range average of about 5 inches)
unbounded we got the launcher to shoot at a maximum of 25 feet per second. so this thing is dangerously powerfull (we even went and fired it at the principal of the school, and OF COARSE he volunteered)
it really stinks that we havent been able to get our closed loop to work, the sensors seem to like to return null values :)
and the camera? *shiver*
we have gotten pretty far along as far as planning goes, and we have a separate team of brainiacs (non-programmer/building but smart types) who are contemplating the posible strategies. im hoping for a good competion seaon this year!
(i hope i stayed on topic.... im not really good at that as my english papers would say)
EDIT: hey spiffizzle... keep going on that design. it looks really nice so far.

Team 1676 had a prototype 1 shooter! :yikes:
~ kit bot wheels
~ small sim motor
~ 1:1 gear ratio
~ Approximately 2000 rpm
~ 1.2 inches of ball compression

Results:
~ Really far.
~ Really fast. :D
Cool! We are at the same step, except we went thru the prototypes 5 times..
Our structure was built out of the kop frame materials.. *SHIVERS*
We started with one KOP gear box, followed by two, followed by a repositioning, followed by using a drill motor.. THEN finally using the exact same set up as the one in your picture XD, except with 1 wheel.. Then we tried it with two... then...
._.;; hopefully we'll be able to finish our real launcher instead of playing around with those stuff.. :)
We are way behind.. T_T

we have one prototype of a mechanism to pick up our balls from the ground that works like a dream. we are now prototyping the frame for that with smaller drums to be put on a ghost chasis that wont be used for more than prototyping. we will then make the final one. were doin pretty good. we are usin the kitbot with the kop transmission cause we are a rookie team and just tryin to get stuff figured out.
My team has mocked up a thrower and collecter, but there is still some debate on how to transport the balls into the hopper.
Our kitbot is built and drive train is finalized.

We have our 'bot fully designed. We'll be using kitbot chassis, and should have a ball launcher and chassis built by the end of the weekend. All the rest of our fabrication is on hold pending receipt of parts from various suppliers. I estimate two weeks from Sat. untill completion, giving us two weeks of drive time.
We may order additional parts and create a practice bot after ship date.0
Programming...progresses. I should have a functional auton. by monday, and a stellar one by ship.

yeah the prototype above uses most of last years transmissions parts and also there are gonna be alot more improvements but this was just proof of concept. the final version is gonna be with more rpms and with a belt drive to conserve space.

A little update as to how far we have gotten...
we have integrated physics caluculations into the code, so that the shooter can actually track the goal.
and it scores 9/10 of the shots.
oh boy a great victory for the programming team tongight! we have autonomous shooting!

I was wondering my Rookie Team was far behind. My teacher insists that we are right on schedule but it is hard to tell, knowing that there is so much to do and so little time left.
We have experimented on the devices to try and discover a system that would effectively shoot the 7.5 inch ball. We discovered that pneamatics would not be powerful enough and using springs was good idea but also did not work out so well in the end. We also tried using a pinball machine design, where a "hammer" would hit behind the ball and launch it forwards, but it again turned out not to be powerful enough. We are now trying to build a system with wheels and a motor to shoot the ball out similar to softball machine at batting cages.
For the electrical stuff, we have laid out the most of the electronics and created the circuits and have screwed everything down to the plywood.
We have built the chasis for the robot and started to play around with the camera, but are running into some technical difficulty.
We have yet to look into a hopper system and a system for picking up loose balls.
Thanks

good point.
unfortunutely we arent able to get mor alum so we are stuck using kitbot.
we are still working on trying to make the motors work and i just found out that wheels cant be chemically treater for traction.
my school has problems with their robot
which brings up another question: have you had problems with your robot/prototype? i mean something like blowing up or smoking. our motors started to smoke
we had that problem with our gearboxes too...i figured out that the lock washer you put on the shaft to hold on the pinion was binding with the other gears...so we removed the lockwasher and just used the newer set screws that were included in the parts bag... try that and they shouldnt smoke.

So far I've been programming like a mad man to get the camera up and running. I've gotten it to drive one of our old bots toward the goal and stop at a certain distance from it. Our ball shooter prototyping is done now and we'll begin working on the real one soon. I'm not too sure how progress is coming on our chassis but its atleast a day behind schedule :( I'll be starting to work on an inertial navigation system today :o
my team has so far completed a entire mock up and working model of a old baseball pitching machine. so far we have been able to easily through the balls at 30-35 feet. we also have our camera pretty much worked and programmed out. so we are on a good course. now if we could only get the real robot to preform just as well we might actually win something. i will hope to post pics. of our mock up for the benefit of others. until have a great time building. and remember to "aim low"!!!!!!!!!! :cool:

This happened to some of us last year, too. We tried trimming the circlip down so that it didn't rub, but ended up just taking it off. We went through the season without a problem. In fact, we just stripped the transmissions for the first time since we assembled them last January, and they were perfect inside -- no visible wear. These are nice transmissions (although our left-hand transmission still growls just like it did a year ago).
Well what worked for our team last year was to have a fully functional prototype by the 2nd Saturday. At this agressive schedule we would be able to improve the final build and have time for our drivers to practice. I would suggest to any rookie team to remember the "KISS" terminology and use what's given to you as much as possible to keep you on a productive schedule.

So far everything is working well. We're a little behind so we should have a completely functioning robot by Monday night.
what's wrong with the kitbot frame?
we used it last year and played heavy defence, i saw no major wear.
(pictures are located at our website (http://www.warp7.ca/new/gallery.php?PHPSESSID=d112a0bfa522a1f56344342bda07 cf26) )
so far we have:
-a prototype shooter working on a large cim motor, but it's not fast enough and it could only score a goal from about 12 feet away and the max distance is a bit more than 30 feet. , it needs improvement.
-we built full size feild parts, center goal corner goals and ramp.
-we're arguing on design
-our custom wheels are being made, they'll be welded and ready to go by next week since we can't weld it with out mig welser, we'll need a tig welder.

I don't know if anyone did this, but if you watch the assembly video from 2005 it says that the set screws will bind, and that you need to replace them with the included replacements...

Yes, but even after you replace them, if that lockwasher is still in place, it will give you trouble. Eventually, through vibration or whatever, it will loosen, fall off, and 50% of the time, bind your gearbox. As Rick said, take it off. It will not make a difference. But yes, disregarding my rant, the setscrew must be replaced.
EDIT--------------------
Not sure if the 2006 ones need it replaced though. Would have thought they'd have fixed that bay now...

I believe that we connected it right. The positive wire from the 120amp cut off switch connects to the 40amp fuse then straight to the victors, right? :confused:
well right now we have disconnected the fuses so that it doesn't run for now. we ordered two more victors and are still waiting for those to come in.

Please tell me you aren't drilling/cutting/filing metal above them? That will kill them really really nicely. Although the RC seems to withstand metal shavings in its pins, the speed controllers don't like them from what I hear.

Note that this is not a real world maximum capacity. I would love to run cosmos (an add-on in SolidWorks) on the simulation and see where the balls lie in natural rest position. I could prolly get 150 at least in there. Maybe 160 *doube the amount available during one match*. :D
The way I put them in was to stack them nicely.
When is the last time you saw balls stacked nicely (re: neatly) in a FIRST robot that looked like a box???

MrBamboo
21-01-2006, 11:29
why does it matter, realistically even a really good harvester is not gonna hold on to more than oh say 40-50 balls at any given time of the match. Something that can hold that many loosely is more than good enough. Considering any ball you score is up to the opponent alliance to put back into field, chances are you'll never get close to having all 80 balls of the field. Plus if you did have all the balls, it's fairly obvious to the other team they can put all their defense on just your robot to stop you from scoring, instead of trying to block several.

No matter how much you do you will never be on schedule. So we are far enough.
I have to agree with that, with only six weeks to build you are always behind schedule :eek:

Let me clarify a bit. This mentor is ME. I am a structural engineer so I don't belong near wires =) While testing out the light and seeing how the camera was tracking, some unprotected portions of the light wires shorted and...well...some melted wire, glowing leads, partially burned fingers (mine), and lots of smoke later, many lessons were learned! Not one of my better moments... :ahh:

Well our team is on schedule compared to usual. First week is spent deciding what we want our robot to do. Second week is spent working on brainstorming. Third-fourth week is spent on designing the robot and machining parts at the same time. Fifth week is spent finishing building the robot. And finally the last week is tweaking the robot and practicing.
By the looks of it this year we’re going to have one crazy robot. We plan on being able to shoot a ball from our robot about every half second (can’t tell you how just yet but wait and see). The robot should have good pushing potential but were looking to just be able to maneuver around them and just unload our robot as fast as possible. The ramp is an obstacle we’re not looking forward to. I don’t know how many teams out there would agree with me but we think the ramp isn’t that important. We don’t have a name for the robot yet this year but people are thinking about naming it Gemini (hint hint) although a few people would like it to be called “Kachunk Chunk” or “Spinning Blades of Doom”.
But right now were going over a lot of calculations to make sure our robot will do exactly what we want it to do. We figure that if we spend two weeks designing the robot and looking over everything three or four times before we build then we shouldn’t have to do much work later.
We did do a prototype so see how accuracy is affected by certain variables. The shooter threw the ball about a dismal 3 feet but that’s all we needed. We also made a machine to help us decide on what material to use for our belting in the conveyor system, we have hope for the material you use to hold down rugs to hardwood floors (works very good and is pretty durable). Nothing is set in stone except for our overall design, no specifics yet but we’re almost there.
Overall our robot is shaping up. I have high hopes for this one. This should be a very interesting game, were going to need to change the battery after every match. That camera sucks up so much power, and with all these motors running our battery should have some fun. Until I can release more details, this is it for now.
Good luck to all teams!
Matt Torrisi
22-01-2006, 18:41
well we came up with this really cool see-saw design to move the balls to the shooter, but as a consequence we couldn't use the kit bot, which though primitive is really strong if put together right. for motors we are gonna end up using either cim motors with DeWalt transmissions for the most power. if the finance goddess blesses us, we might put 4 cims for extra power. we like push power :D especially with the defence quarter thing. we did that last year, so we are just waiting on parts
i made a shooter merely using the old bot for a platform and the softball launcher design. separately we got the camera to work after much tinkering.
are we the only team having problems with the camera locking onto ceiling lights as well as the target?
DjAlamose
22-01-2006, 18:57

You are not the only team that has this problem. This should be a problem for all teams. This is because the florescent lights give off a green hue as well as other hues. The camera will pick these up and then target them. At most places where the competitions have been held (I know for sure at Great lakes and Buckeye) the lights there give off a red hue. It took us a while to figure that one out last year.

also the CMUcam is pretty good at seeing UV light, and the florescent lights give off quite a bit of that (hence they're modified for use in tanning salons)

I totally agree, how could anyone already have there whole robot built. To really design a good robot you need a few good weeks of brainstorming. We just started to build only at the beginning of this week, we have a lot done but still have more than a week of build left.

So we are now about half way through the build season. How far is your team?
We are running really behind this year. We have a lower frame, alot of parts on order and a bunchload of CAD drawings. We are waiting for a bunch of parts which are being made out of house because we have very limited machine tools.
Hopefully next week we will have a completed drivetrain and launcher.
We could be further... it's been driven, but the major ball shooting components have yet to be completed. *shrug*
Like most teams, we're running a little behind, but it's no big deal yet. Ball shooter, drive train, ball storage, etc have all been designed and prototyped, and the students are now madly building it all. I suspect the final drivetrain will be done this weekend for testing and programming.
Is it Feb 21st yet?

1293's making progress. The drivetrain is getting assembled, and should be able to be driven (if we throw on our practice bot electricals) by the end of business on Saturday. We could probably have gotten it by this point if we'd received our wheels and other materials before last Saturday, but such is the way of shipping. I'm not worried there.
The scoring team has pretty much nailed down the plan, and the CAD drawings are coming fast and furious. I'm not working with them too much, so I can't go into further details.

The shooter design is done... sorta. The hopper and ball pickup is entirly up in the air. We have a couple of designs for each, but we're divided on which to chosse. So, in a nutshell, we're having a tough year since we have maybe five kids working on the robot and a couple of mentors.

Our design an dprototyping is done and majority of the parts are being sent to the fabricator and welder. Since we cant do much machining we are having it done for us. We can shoot make it up the ramp and have picked up balls with our prototypes. Hopefully we will get parts tonight and assemble the majority of the drivetrain and out lower construction so our programmers can have fun while we work on the ball collector hopper and shooter. Also we are working on building are cart (well actually fixing and modifing), and our control panel operators controls. My prediction is end of the fourth week at most 5th week. Then practice everyday for the remainderr of ther build season.

27-01-2006, 16:25
To put this in perspective...
At this time in 2004, my team was sitting around in a computer room, tossing around ideas, after physics of the frictiony ball surfaces made our original one impossible. I think this was also the week where the frame was started in construction, and CADing began.
At this time in 2005, we had a prototype claw, later abandoned for a more effiencent one, a CADed arm which was built and changed drastically in the 72 hours leading to the arrival of the FedEx guy*, and we knew what our drivetrain would look like. Our code master was hard a work trying to get the camera to work, and when he gave up, turned to encoders.
Right now, we have 5 prototypes in the shop, 3 of them fuctional, a sixth recently taken apart for testing purposes. We have the drivetrain to a T, V1 of the frame is constructed, and our electronics board is together. Our much larger than previous years coding team is hard a work, and after a rough start with the camera, is making progress in leaps and bounds. We know exactly what our shooter will look like, and have only one or two refined choices for other systems.
That doesn't mean much though, we're still behind schedule. :D
*Yes, there's a reason why I said 72 hours instead of 3 days. :eek:

Shooter:
The shooter itself was prototyped, and failed. :(
Going with another design while we'll further prototype, later.
The rest of the shooter mechanism is in design.
Much more to prototype before its final configuration.
Programming/Auto/Controls:
Err... This is ALWAYS our downfall.
Mostly, we know what we want to get feedback on, but how we're going to get that feedback is still in the air. In the meantime, we're dealing with resolution issues, and how design some of the mechanical system to work within that resolution. Most sensors in-house, or shall I say, in the KOP. Uhg...

So we are now about half way through the build season. How far is your team?
We are running really behind this year. We have a lower frame, alot of parts on order and a bunchload of CAD drawings. We are waiting for a bunch of parts which are being made out of house because we have very limited machine tools.
Hopefully next week we will have a completed drivetrain and launcher.
robot, he he, what robot? today became stress day because we don't even have a working launcher yet.

Team 1676
20mm item extrusion chassis!
Welllll... We have a prototype shooter, a frame kindasorta(notreally) built, a design on the way (that will hopefully be finished by this weekend), plenty of idle hands... and a freshman with a broken finger.
Anyone want to trade freshmen?
Edit. A freshman with broken fingers. Plural, people. Gosh.

Well, 279 is about where it always is. We get the drivetrain portion of the robot done quicker than the rest and then add the game objective portion to it.
The drivetrain is coming along, I haven’t taken a look at it in a while but by the sounds of it, we should have a moving machine by tomorrow :D .
The Game Objective portion of the bot is halfway through the design process. The ball shooter is all designed finally! We are making parts for it tomorrow so expect another teaser. Also the ball collecting portion of the bot is coming along. We should have a final design after tomorrow’s meeting. We had some issues with how fast we wanted things to run, and then we decided that if we moved a ball 48 inches in 1sec that it would be too fast and unnecessary. But we seem to be ahead of where we usually are. Progress is progress :rolleyes: .
Electronics/Programming
Have no idea how far they are. They decided to use last year’s code for the cam and it works better I guess. But they don’t have a list of sensors of controls yet so I don’t think there is much they can do :ahh: .
CAD
Umm I didn’t know we had cad…. :eek:
Scouting/Spirit
Saving that for the two weeks between build and regionals. :]
I think that’s it. I truly feel that we are ahead of schedule for once! Besides, who needs driver practice anyways?

he he, uh Reds Robotics doesn't allow freashmen. :p you have to go through a year and half of eduction in electronics and robotics. Beginning Electronics(resitor, led's, and etc.), Advance Electronics (Demulitiplexer/mulitplexer, binary code, and etc.), and finally robotics(like the bobot but cheaper, make the chassis yourself and give the robot different behaviors according the currant lab give like make it follow the wall, or drive away from the edge, and solve maxes, stuff like that. :)
WE GOT OUR ROBOT TO MOVE!!! YAY!!!
unfortunately its first action was to proceed to run me over and try to flatten me.
3 weeks later and only the kitbot works???
i think we are in trouble.

306 Update 1-31-06: At the halfway point, we have a driving base and a completed ball pickup+assorted essentials. We have a shooter, turret, and hopper in the works for this coming week. Programmings going to need some time this year...

So, is any team out there done with their robot yet?
Or is there any team that hasnt built anything yet? :eek:

If you haven't built anything yet you might as well pack it up and start planning for next year.

By the definition of the word I don't beleive our robot will be 'done' until reigonals are over. :D

Well, from what I hear, you're not finished until the robot is put back in the crate and shipped home. I've seen a few stories here of last minute tweaks done during competition...
As for being finished, our team is not entirely done. We have the mechanical part of the robot pretty much complete, and all we have to do is mount our electronics and wire everything up to see how it works. Of course after that there are those unexpected problems that you never anticipate, so we'll probably be spending a bit of time coming up with solutions for potential issues.
Then after that, the remainder time should be spent practicing and creating extra parts if needed (you never know when that important peice might break).
There really isn't an end here is there? It just keeps going and going and going...
237 has been finished since the end of week 3...
now could someone please explain this robotics thing you guys seem to be so crazy about to me?
My team isn't done yet. Is that really bad? :O

Not bad, by any means!
I think most teams aren't finished!
No worries, you still have a little bit of time left :D
1089 has a driveable base.
I'm under the impression we should be finished some time this weekend.
We aren't done. My guess is the robot won't be done until mid-next week, like usual. Poor planning usually is the result for this, but this year it's been partially do to leadership problems (we have 5 club officers; only 2 of the 5 that started this year still remain officers). Some too much work, some not really motivated, etc., etc.
We do have our whole design done though, and have all components at least started. The problem is putting them all together and giving us enough time to get the code working with the robot.
1978 hasn't built anything yet (Barry Goldwater High School from nearby here in Arizona). Their kit arrived 3 weeks late (last week Monday) due to registration problems, and was missing a few parts, plus they did not have enough funds to buy basically any additional parts for the robot. We've given them some materials to help, and it looks like they have a design reasonable to finish in the time they have. We'll help them as needed; I hope they get something built in time for competition.

We've had the worst luck with ordering parts...our frame peices were 6 days late, and 3 orders we made were never confirmed...we're behind from our set schedule, but on track with previous years. My only concern is that our design in more complex than we've ever done before...we might be working long hours on competition Thursday...

my team...well...um... we opened the box and umm... we put together the kitbot sort of and umm... :confused: i dont know what else we did
how far have other teams gotten?
Were done. 4 weeks. kick $@#$@#$@# robot.

We got off to a rough start, changed our design quite a few times, communication issues. Finally looks like a Robot........OK, maybe not ;)
Team 1208 is definitely behind its projected schedule. As usual.

Our team is almost done with the chassis (I hope) but we are far from all the little things coming together. The shooter is in pieces as we just disassembled what we had done to paint the robot.
Our software guys mounted the camera on our robot from last year and have autonomous code running so that they can learn how it works (will later be adapted to our new bot - 2 wheel drive old bot, 4 wheel new).

Team 1011 is less than 2 days from shipping and we took the bot apart to paint. How is that for audacity...LOL! We have shooter, collector and dumper and only came in 8 pounds heavy at our first weigh-in. No kit bot for us. We used steel! We are rebuilding today, driving tomorrow and fine tuning programming issues and off to dryage Tuesday! Good luck all, and see you at Phoenix or Las Vegas!

Well...
We were going to be done by saturday, wired by sunday night, and driving monday and tuesday...
Then we checked our weight- at 9:00pm Saturday night we were projecting a weight that was 20+lbs over the limit. So, saturday night we started hemorraghing weight, and today we attempted to re-design...but everyone was exhausted and non-functional from the night before (loooong night). Right now we are starting from the base up (no pun intended)- we are maintaining our drivetrain and base, and our collection method. Tomorrow we will build a corner goal delivery method(goal #1), a BASIC shooter(goal #2), and various other things...(goal 3). Wiring will probably be designed in fix-it window and done on location @ Drexel...
Wish us luck!

Our team is now chillin'. We finished all major aspects during the weekend. The robot drives and shoots accuratley. So yea we happy. only thing we still need to do is rewrite some acceletation curves for the turret.

Well, we got a good amount done. up until this point the majority of what we've been doing is setting ourselves up for success. This includes improving organization and places to put tools and stuff to increase productivity. By the way, it has worked very very well, so anyone that doesn't have good organization, get some. It's amazing!
We've set up our driver station and our high school students all are given laptops by the school so we set up everyone who is even thinking about programming up with Labview and we have some pretty awesome ideas for our robot. We've already prototyped some kicking mechanisms and we have built a mock field to practice strategy.
Hawaii DOE has Furlough Fridays oh fun and that means that we dont get to enter campus on fridays it really delays us :mad:
