What do you think of team 61 robot
 

Give some feedback on what you think of team 61 robot for this year.. If you have any questions i will be greatly glade to answer them.. Although i can't tell you everything i can tell you some stuff about it.. We have our own secrets two you know!!!!:D

o ya our robot you can find it in the gallery or click on the link below

it looks pretty coolio..heh i like the drive train, but i cant really figure out what those bars are gunna be for unless you still need to add some kind of grabber thing on the end of it, but anyways it looks cool, compared to all we have is drawings on CAD at the moment...:rolleyes:

Ok...
So what's it do?

Its designed for plowing through the boxes and being the KING OF THE HILL.... The arms are used for blocking and for moving boxes so we can hold on to them some what.. when the arms are extended through the front or rear they are 5' apart and from either side they are 7' 2".. They are made out of steel.....

well, since you have the old bosch and old chippy on that bot, it looks like you still have a lot of work converting your old 2002 bot

thats our robot right there we just have to put the motors on the arms and we are done......

Good Strategy...but....
 

What are you going to do if the boxes aren't there when you get there?

Have you got good backup strategy in case plan A can't be achieved?

Yes we do but its still kind of being worked out...

did some one say we are converting our old robot for this years competition?

Yeah some one did, but i hate to break it to you, its a brand new robot, brand new everything (well almost) Thanks tho :D

What's not brand new?

if i told you i would have to kill you... =)

Yes we would........................... :D

Isn't that the same base as last year?? As in drive train, and body and everything inside?

http://www.valleytech.k12.ma.us/Robo...2%20Gears1.jpg

Last years drivetrain: Note the smaller drill last year.

http://www.valleytech.k12.ma.us/Robo...op%20View2.jpg

Last year body: note the nice paint job, note the steel in the front, note the back of the robot solid wood.
Look for the drill holes from last year if you think this is last year base.


Look at 2 year ago base: This look more like this years robot.

Look at 3 years ago robot:

http://www.valleytech.k12.ma.us/Robo...s/roboti73.jpg







Do you see a pattern. We stay with something that works. We build a new base every year. We make changes as we go like this year we build strong rail system for the tracks. Different tracks this year, it is hard to tell but yes they are different. Look at the motors they are new because of the new drills we got. So if you think in any way we do not follow the rules you would be wrong. We like to be able to put our robot together quickly.


Why change the design every year. This way we can spend more time on the task at hand.

Nothing says we can't use the same design we just can't use anything from the last year parts unless noted in the rules.

Take at look at our web site and you will see all the different robots each year. We don't have picture on the web from our 1994 robot but you would see the same style as we have now the only different is it was 36" wide instead of 30".

I wanna know how much those huge metal beams weigh.

Greg

i dont see this robot as doing very well for king of the hill, i might be mistaken but if the arms dont have contact with the platform i see your robot spinning around when someone goes after the end of your arm

the two beams with the centers in them weigh in at 35Lbs.


Just think if you get these long arms spinning like a top and someone tries to come close what do you think is going to happen.


the low center of gravity and the way the tracks are we have pretty good traction on the top of the ramp.


the point is not to be at the top until the end of the match. Full speed with arms out will push a couple of robots off the edge.

the arms and a strong robot will be good to knock over anybody stack even if they try to stop us. remember if your robot is touching any part of your stack that stack does not count. if a robot pushes into your own stack then you lose those points.


This is just some of the thing a strong robot can do. The field is open due because our robot can go under the bar so it would be hard to block


for those fast robot that knock the center stack down quickly our arms are wide enought to push them back up and over the ramp.

Not if they have a firm hold. Track systems are good on top of the ramp and on the carpet. The ramp slopes however poses a problem. One of the reasons for having a track drive is for more points of contact. At the top and the bottom of the ramp you lose the advantage contact points, and you are no different than a four wheel drive robot. So, if a robot on top has a firm hold close to the edge of the ramp, odds are your tracks are no advantage. Note: the center idle wheel could also cause you to teeter at the top.

Explain exactly what you mean by this.

Greg

DId you say 7' 2"?

With that span and the side area by the bars only being 6' wide a see a small problem with going under the bar.

looks to be a very simple robot. which is good, as simple robots are easier to fix, and they seem to break less often than complex ones. The tracks will give you guys plenty of power and traction. I dont know how well those arms will be at blocking robots, bu they look like they could be hepful in herding boxes/ stacks around. Nice job. Good luck

Thank you Mr.Norton for explaining every thing, there are some doubters out there in this crowd

That is with the arms fully extended. Think about it if we were 7'2" to start we wouldn't fit in the box!

Yes but if we come up the ramp at full power we will just go through you..... And i know that our driver has no problem doing that we have destroyed other robots in the past!!!!! :D

Um yeah, Last I checked I don't think you are literally supposed to destroy your opponent, but what do I know.

Yes well stuff happens at time!!!! :D

yah...i thought that too...

Well we are not out there to destroy anyone just to have some fun and we are going to be the KING OF THE HILL and thats the way we have come up with staying on the top...

Not since I've been in FIRST. Ive seen a few collisions that caused some breaking, but not intentional damage..

Yeah, which would lead to DQ's if the refs believe is necessary

Could you post a pic of your robot with its arms fully extended out? I'm having a tough time trying to imagine how you will guard the top of the ramp- Thanks

lets hope you dont do that because you prolly wouldnt be able to compete after that would happen.

you cant just intentionally go all out and try to destroy

Well we don't go out and damage robots intentionally we have never destroyed a robot with intention.... We just go out and fight until the end!!!!!!

this is our arms open they are 7' 2" from tip to tip............

http://www.chiefdelphi.com/forums/pi...&quiet=verbose

Now do you think we can guard the top of the ramp.......

(last year) Below is a picture from the PA robot challenge.....

http://www.valleytech.k12.ma.us/Robo...20goal%201.jpg

Oh yeah- now I remember you guys- you were one of the few teams who could actually push us around last year.. your tread system sure is amazing

as long as you can rotate these arms, you'll probably be able to do a good job on the hill

we test one of the arms on Friday with the motor and it works sweet.... and it has lots of force....


and for the ones who think we don't have a lot of power look at this picture it will change your mind.....

http://www.valleytech.k12.ma.us/Robo...ng%20Robot.jpg

Very intesting strategy... but as I told the person from my team who wanted to play king of the hill.

"WHAT ABOUT THE BAR?"

Greg

61 has a great drive system. the only team i saw who could push them around consistently last year was 180 SPAM.

One thing we can always count on <knocks on wood> is that FIRST is going to implement a game that requires a decent drive system. Once a team 'masters' or develops a drive train, they tend to stick to it. It will be interesting to note how many second generation swerve drive teams will be present this year :rolleyes:

<curses being a rookie team with no fabrication machines>

Hey guys it seems like you have gone for another beast again. Question what is up with all the wire in the picture is that for the swinging arms? Lastly do you have any securing device to make sure your on the ramp? Well we will see you guys at Regionals who knows we might be partners (me begins to think of possibilities) Regardless friend or foe we will see us on the ramp;)

I would just like to make something clear, by saying almost every thing is new what i ment by that is our robot pretty much looks the same and it looks like last years robot but every thing is new. except for the way our robot looks. So for any misunderstandings out there I just wanted to clarify that. Sorry for the confusion

Spam team did not push us around. It would be more like a even power robot. If you go back and look at the two times we play them. we took a goal away from them and block them from getting back to there home base. and the second time our partner could not move so we left spam alone to try to get the most point for both teams.

those wires are for the main motors we are using the 30 amp breaker until we get our 40 amp breaker. The wire you see is for the arms. we have two pulley that pull the arms in and out.

We are using the Van door motor for one of those arm. We gear it down so the power in the one arm can move a robot without us moving the base. just in case someone wants to block there stacks.

If you saw are robot last year, we go the same speed. with a little more power. We do have those new drills. and 40 amps.



What about the bar. you guy can go under the bar and do what ?drop our stacks. by then your stacks would also be down. it would come down to who is on top with those points.

People think you need to be at the very top . Just think if there is a robot on the ramp do you think you can power the robot up and over the top. the robot on the top of the ramp looking down at the other robots will have the power of gravity plus there power of the robot.


watch and see what happens. I would say a lot of the point will be gone in the first 15 second. it will be up to the other robots to defend those points. So power this year might come into play.

Agree

okay can you verify your statments to me, first it looks like you are gonna purposly going out to destroy other robots, i say this because most people would not go out and say that they are gonna plow right through other robots and that your team has no problem with destroying the other robots, and then your secods statement looks like you are contradicting your previous statement, i am not trying to start a fight, i am just a little confused

I have not talk with this student yet. But Team 61 plays by the rules. We will not go out and destroy anybodys robot.

Our robot is to move things around. if you look there are no weapons on our robot. I will have a talk with Walter about his statements I am sorry about this.

I didn't mean brake robots i meant push them around and when you start pushing robots around and you defend your spots whether its on the hill or from other robots plowing the tow of buckets over.... Any thing can happen..... I am sorry for the way that i worded that it came out the wrong way....... Well I think team 180 spam had a great robot last year...... The only time they were able to push us around or pull us was when our track broke...... Well i hope to feel better soon so i can post some more and go work on our robot....... Talk to you all later......

Breaking robots
 

I'm actually going to agree with Walter here. If you read the rules, it states that robots should be made to endure. Ramming is going to be a very large part of this game, and any robots out there should EXPECT to be rammed if they are at the top of the ramp. If their robot breaks, it is their fault, because controlling the top of the ramp is 61's strategy. Unfortunately, 61 is NOT in our regional, lets just say they would not be pushing us off the top of the ramp, ever. . . .

Many teams have said just that. We have not run into a robot yet that has stop our power. They have slowed us down but not have stop us.


Power is going to play a big part this year.

http://www.chiefdelphi.com/forums/pi...&quiet=verbose


Just beware of the power. and by the way we are only 9" high the center of gravity is great only 3 " off the ground.


There is not much that can go wrong on this robot. So we have to find some other way to spend or time in the pits. :D

Looking forward to seeing team 61 at Regionals.;)

EGO??

stole the words right out of my mouth- seems like everyone is saying "You can't push us around" .. Theoretically, everyone will be pushed around except for one robot, so the bragging rights belong to last year's pusher- Beatty..

Even Beatty got beat so noone should brag until they bring home the hardware. This is a new season so as far as I care a rookie could be the most strongest bot. Right now this is all a bunch of talk we will find out tomorrow (in Quincy) and at the Regionals whether teams that have been talking can walk the walk. 99% of the time they can't.

well, i'd probably put it at 75%, but otherwise I would agree.
And even the best bots break every now and again.

since when is aluminum invincible?

there's a difference between team spirit and being pompous. i've seen a few teams that are being very arrogant in their comments, and making very absurd predictions. for example, not being able to be pushed around. unless you can take another robot from another team and ram your bot, you don't know. human power is nowhere near that of a bot. another example is their bot being "perfect" and not needing to work on it. there's ALWAYS room for improvement.

lastly, i would like to say that your bot looks nice, but i'm sure it has its weakspots just like any other bot.

*jeremy

Time to cry =( Ya'll will find out! Mr.Norton will be posting soon =(

please try to hold back crys or joy

The only problem we see this year are the bins. Were in the rules say you can't try to go under the bar just because there is a bin in front of you. We hit a bin at Qunicy mini-meet and we stop short of making the bin go under the bar. are robot has enough power to push the bins under the bar. some of the bins will bend and others will go in many pieces. Is it the fault of the robot trying to get to the other side or is it the fault of this year game using something that will break under high loads.

I really hope they have a lot of bins.

One other thing I hope the other robot protect there robot good. one arm start at 7" off the ground and the other at 8 1/2" off the ground. we did not play against any of the robot at this meet because of the thought of breaking them before they had to be shipped.


So please protect and cover everything up.

Our robot is made to push a lot of bins, if another robot comes in contact with the arms, the arms will go through the robot if the robot is not protected.

We have to cut more gears because the gears we are using out of Stainless steel 1/2" twisted. You can see the out put power of this robot has. We will be trying to use stronger steel.

it is nice to have a machine that cut your own gears. We have gone through 4 set of gears already because of the power problem.

we will see everybody down in FL.

Sooo....what you saying is you robot hit robot...no....robot hit you robot...no...I dont now. :D

sorry i was stuck in norton neanderthal mode

team 61 you r robot gods i bow down to your mastery of the electrical arts and yo u r superb electrical skills




--Its only funnny till someone gets hurt then its hilarious--

Not really necessary to post this kind of message

HELLO!
 

If you have gone through 4 sets of gears why don't you start using chains and sprockets. Is it because the gears work so well hmmm???

Well, first of all, let me say that is a fine looking robot.

Now for some questions. (I didn't read the whole thread, so if it has been answered, please point me in that direction)

1. If a robot comes charging up the ramp and it hits one of your extend-o-rama arms at the very end, can those arms take it? Are they designed to snap after so much forcer? Or will they just bend/throw your robot off to the side?

2. How is your turning? I see you have treads, so that would give you a 0' (in theory) turning radius, but do you skip or any other problems thanks to friction? And what about going up on an angle on the ramp? Are you OK at that, or are your treads off the ground when you hit it at an extreme angle?

3. It seems like you have a guide-wire extend-bobber that retracts it. If a box (or a robot flying over the ramp) comes and hits it, will that be damaged, or is it bomb proof?


4. It seems as if the slightest bit of bend in your arms will not allow you to retract them? Do you see that as a problem?

Well, that is enough to say now. Hope to see you people at a competition!!

Arms are made out of steel and won't bend or snap.

We spin on a dime and do not skip around. We go up and down the ramp no problem.



Cable was strong enough last year to tow 2 goals and an upside-down robot all at the sametime.

Don't foresee arms being bent.

Both arms are made out of 1/4" square tube Steel. The arms alone weigh in at 50lbs. I do not think these arms will bend.

Second these arms are made to take a strong impact and yes hard enough at the ends of those arms the robot will turn. What make it nice is if they do come in contact with another robot the arms will center itself when they hit the side walls of the ramp. When the humans controllers have control it is very easy to bring in those arms.



I guess you have never seen or robot in the past. We have always used tanks. We turn on a dime. to program this robot it is very easy because it will do the same thing every time. That is why we can make it up the ramp as quick as we do. it is not because we have a very fast robot, but it is because we waste no time at all on turning or moving.

If you look at the picture you will see how easy it is for us to go up the ramp. Not only do we hit the ramp at full speed we have are arms out and ready. We have been doing ramps in the past and we have no problem going up, down, or side ways on those ramp.

That is the weak link. but it is in the back of our robot and we have spares. It is a solid piece of alum. no box will hurt it. It would take a hard impact right at that spot to hurt it.

About the arms It would take a lot to bend them and if someone does bend them we get a big Big hammer and bend it back into shape. But the arms them self will be able to move any robot by itself if our robot has enough traction to stop it for moving backward. The arm is run by a winching device.

The arms are always in high tension with the cable.

The problem is that we twist the output shaft. We do use sprocket and chain on the weaker parts.


The gears work to good these are custom gears. They mate perfect. It is when you ask of them to do something that the steel can't handle.

We are know finding out what is the hardest metal to use. So we don't run into this problem. I would like to see any other robot rip a track that is rated for 1400lbs of torque

that is what happen when a robot stops and the motors are still going. We almost took the walls down that are on the side of the ramps because we were still getting the bugs out on the program.

We, also, used treds for a few years, but we found out as soon as you try to go up a ramp, all that touches are the front/rear spots, which is very-very small. Do you forsee this as a problem if you decide to get into a pushing match while on the metal grate?

We have test them out when we had to fight for the ramp a couple of years ago and then grab the bar to pull yourself up.


This works very good.

It scares me a little...
 

Please don't not take any offense to this comment. I think your bot might be a little too powerful. And a little too risky. The first thing it did once on the field was obliterate a box. That can happen once but not twice. Plus if your arms protrude out of the boundaries the refs might disable your bot.

But overall great bot, just becareful not to get disabled;)

I had something about the bin


Can you answer this


We don't take any offense to that. We built our robot to be strong.


The question I have for you is I did not see anybody else use the auto mode. in the meet.

This is what we did well Hit four stacks within 5 seconds. Most of the time we were alone because other could not get up there that quick.

This is without any deals playing straight up.

We won 7 out of 10 matches in the seeding rounds
