2594 Robot Preview
 

This years robot, week 4, not yet finished. Still have motors and annodizing to do. We need to mount our electronics as well, in the back. Drivetrain and front brushes working, moves well. Tell us what you think.

Re: 2594 Robot Preview
 

Very nice! What kind of motors will be driving those blue brushes? I'd like to hear more about the delivery system. Its a well professional looking robot, and I like the drive train as well.

Re: 2594 Robot Preview
 

The blue brushes will be driven by the DENSO (window motors). As for the delivery system we don't have any finalized choice, but we have a few working ideas.

Re: 2594 Robot Preview
 

Does each pair of brushes spin independently? Or some as pairs? Or all together? Looks great!!!

Re: 2594 Robot Preview
 

The top three brushes and the bottom three brushes work as groups each run by its own DENSO. The top three will be trigger operated.

Re: 2594 Robot Preview
 

Yah, the brush system was one of the easier parts to design/build. The drivetrain was a monster... Just so you know, Van Tassel didn't mention it is 4-wheel drive, AND 4-wheel steering... Here is a pic that is a little closer in so that you can see, as you can tell it isn't fully assembled at this point, it was a few weeks ago. We are using that mount right there to pivot the two tierods that attach to the custom wheel brackets.

Re: 2594 Robot Preview
 

Beautiful design, I love both the drivetrain and the manipulator system!

One thing, I hate asking this question, but how are you mounting bumpers?

Re: 2594 Robot Preview
 

Although it looks very difficult with the drivetrain we actually have bumper brackets planned that should work, but not physically there yet...

Re: 2594 Robot Preview
 

I can't wait to see a video or two of this bot moving and shooting. Coming from a second year team, I am highly impressed.

Re: 2594 Robot Preview
 

I actually have multiple videos that i have taken off of cameras and cell phones. They are just of the robot driving though. The thing is that I don't know how to get them onto the site, or youtube. I need some help with that, if someone can help me convert formats or something like that I can get them up. Especially if you know how to get videos off of phones...

Re: 2594 Robot Preview
 

looks good, would be interested to see it actually working... Too me in my opinion it looks rather elaborate...

but if it works thats sick...

Re: 2594 Robot Preview
 

The driving works amazing and the brush system is currently being tuned. Even with the slick wheels we have almost perfect control with sliding, and we were even playing around sliding it with out feet and purposely doing drift and we EASILY got out of them when we wanted to. I really am wanting to get a vid up now...

Re: 2594 Robot Preview
 

Random question:
Are you gonna have really long brackets extending for the bumper mounts?

Re: 2594 Robot Preview
 

Bassically, there is a little more than that but same concept.

Re: 2594 Robot Preview
 

Ahh. Well it's good that you've got it all planned out. I was just a little concerned XD

Re: 2594 Robot Preview
 

A little more than that meaning something structural, right? Something like aluminum tube, say?

Re: 2594 Robot Preview
 

Yah, in my original design (I did the chasis/drivetrain) I couldn't do bumpers, so what i did was manipulate it so that we had some spots to mount. The exact spots and brackets i'm not so sure about but i am told that it should be fine by a couple team members on the mechanical team. I am trusting them that it does work or else we got a problem i guess huh? I am trusting that they are doing something that can take hits from other 120 pound robots, they are smarter than that, I hope... :D

Re: 2594 Robot Preview
 

That core frame looks like something that should be on Mars... ;)

Re: 2594 Robot Preview
 

Just make sure that <R08-M> is satisfied. (And the GDC says through Q&A that 1/8" plate on standoffs, unbent/untreated, won't work.)

Re: 2594 Robot Preview
 

KK thx, i will look into that right now just to make sure...

Ok. Good call. Like I said, I'm not personally working on the bumpers, but I will make sure that the people that are know this rule. I did design the chassis and drivetrain so that there was extra room, so it should be ok, but no harm in making sure. Thx again.

Re: 2594 Robot Preview
 

How could they say that without knowing the spacing and design of the standoffs? Eric, can you post a link to this specific ruling? It doesn't sound like the GDC to say something like this before an actual inspection of the robot in question.

Re: 2594 Robot Preview
 

That is by far the most creative robot I have seen this whole competition!! Good job!!

Re: 2594 Robot Preview
 

I hope the brushed designs work out well this year (for both our sakes)!

How much distance can you get out of the denso motors for shooting? It seems to me like it would have been preferable to swap your intake and shooter motors so the FP's would be firing balls.

Re: 2594 Robot Preview
 

I sure can.

Here's the original question: http://forums.usfirst.org/showthread.php?t=11349

Here's the followup question, where they actually provide guidelines: http://forums.usfirst.org/showthread.php?t=11503

They pretty much said that 1/8" plate on minimum standoffs won't pass, but taking that same plate and altering it for strength, say by making it into a C-channel, will. It's up to the inspectors, yes, but the initial ruling ruled out the standard method that teams might use.

Re: 2594 Robot Preview
 

....too all the teams competing in Portland, I would watch out for NASKCO's robot......"the Skorpion!" ~ ....aka....Naskcorpion! ~

Looking great team 2594!...."NOW GET BACK TO WORK!" :eek: ...before I have to bring all my kids with me to help you....

....there " are only 9 days and 16 hours before it needs to ship.....

:ahh:

Re: 2594 Robot Preview
 

That is beyond sick.

That is perhaps one of the most unique and aesthetically pleasing designs I've ever seen. Good Job!

Re: 2594 Robot Preview
 

We were figuring we can do anywhere from three to five feet all the way to fifteen depending on how we decide we want to shoot, we think our objective is to get close, unlike alot of other teams we were watching on youtube that were going twenty+ feet. We see no need to try adn hit a small target across the arena... but hey, teams should know this, how often can a gameplan change when you actually go to regionals and you see taht yours doesn't work adn another one does...

Re: 2594 Robot Preview
 

I can't beleive you said this todd. To everyone that read "The Skorpion", todd must be tired because we have picked NASKcorpion, making a pun with our name (NASKCO + scorpion)...

Re: 2594 Robot Preview
 

I really advise you guys to take a look at all the Bumper threads and read them in detail. The rules are still confusing for a lot of teams. Looking at your frame you are going to need some serious thinking about how you are going to comply with the bumper rules. Good Luck!

Re: 2594 Robot Preview
 

Ok, I have just looked at the design that they have for the bumpers to go on, looked through the rule book twice, and it works. No rule violations as far as I can tell by looking through it twice. How the bumpers mount for now though, unfortuantly to all other teams, is currently classified. Sometime next week I will post pics, sorry. ;) ;) ;)

Re: 2594 Robot Preview
 

The Naskcorpion is showing some serious progress with 8 days left.


Everyone has had to really pulled together at the 11th hour (literally) to shift the steering inward by 5/8", inorder to accomodate the bumper bracket.


Everyone is focussed on getting this done asap, as there are only 8 days left before it has to ship!





Good times! Team 2594 is doing an excellent job under pressure. 8 days left!

Re: 2594 Robot Preview
 

affter looking at your design it looks solid but have one question are those wheels legal

Re: 2594 Robot Preview
 

The wheels you see are what came in the kit of parts. What your probably wondering is if the white hubcaps with the NASKCO logo are legal.......we haven't seen anything in the rules about hubcaps being illegal. They are pretty cool eh?!


Engineering teacher Roc Cox and our mad scientist Robert Canella working on the brush assembly

8 days left!:ahh:

Re: 2594 Robot Preview
 

I can think of one or two ways they could be. 1) They contact the floor. Not an issue here. 2) They involve modifying the wheel in such a way that traction could be affected. It doesn't look like either is in play here. Then again, I'm not an inspector or member of the GDC.

Re: 2594 Robot Preview
 

I love looking at the images of robots that teams post as weeks go by. I'll admit, I usually use them to gauge 1339's progress as compared to other teams, and to look for potential issues. This thread, however, has absolutely floored me. Your robot looks amazing, and completely aside from any issues related to competition, rules compliance, or scheduling, I am in awe. What a fantastically realized design! More power to you and your outstanding team.

Re: 2594 Robot Preview
 

got a video? id love to see it :D

Re: 2594 Robot Preview
 

....I would love to post a video as there is only 8 days left! :ahh: But, the software guys are still drilling holes (...yes! the software guys!)

...here is a front view of the Skcorpion.......


The NASKCO team (#2594 ~ Portland regional competition) greatly appreciates everyones encouraging words. They were working on the robot after midnight last night.

....crunch time.:P

Re: 2594 Robot Preview
 

Excellent work guys! Just make sure that you have a good bumper system by the end, otherwise you're pretty much dead! Also, how do you know if you have a good center of balance for that thing??

Re: 2594 Robot Preview
 

Nice robot! Good luck this season. :cool:

Re: 2594 Robot Preview
 

Ok, with the issue of the wheels, as eric pointed out we are using the KOP wheels and not affecting them in any way, and the hubcap locks in inside of the wheel so nothing touches the ground. Our hubcaps are printed out on a 3D prototype machine so they are legal in every way shape or form, that is unless the judges think it is so cool that they throw us for unfair advantage. :). Also, the main tube design is made out of a very light aluminum so that there is vry little weight. We are designing all of the electiracal parts to go on the bottom, so our center of gravity is theoretically very low. Unless for some reason we add a lead weight to the top that should be fine too. Thanks to all of the comments from all of the teams and mentors that we are getting, your guys' comments just keep motivating us to finish and do well. We are very excited to go to competition now and see all of the others.
One more question that I ahve been getting is about videos. I am currently trying to get some vids up there, but due to my lack of knowledge when it comes to that I am struggling a little bit. A note to everyone that would like to see a video. On monday I am giong to the district's tech teacher and he said he will help me get the vids up. SO... by noonish Mountain time hopefully I will have videos up for you guys.

Thanks alot for the great comments and feedback. Good Luck To all from NASKCO!!! :D

2594 Up and Running
 

We got our robot operational on Saturday night, or should I say Sunday morning? Well, it works, about as well as we were hoping it would too. Now it's time to tweek the programming and get some practice in. Good luck to everyone. :D

Re: 2594 Robot Preview
 

Ok, it is monday at about 3 in teh afternoon. We are testing the programming tonight and so hopefully I will get videos and pics uploaded by tonight at 9 so that you can see the balls shooting, and I can too. :) This of course is a goal and definetly not a guarantee. I promise nothing.:p

Re: 2594 Robot Preview
 

HERE IT IS!!! Robot as of now, (last touched at around 3:00 Sunday morning...)


Our beautiful wiring mess... Not that bad actually...


Sorry, it's sideways...


To all that where curious how we are doing our bumpers, and yes, as far as we can tell it is legal. (basically a fender on a car.


There have been many teams wondering about brushes, so here is our design, and it is tested and works well.


And how the balls are picked up, the opening is about 7.5-8 inches wide.

I meant for the pics to be blurry, so you guys can't see all of our secrets. JK, SORRY FOR SOME OF THE BLUR, NOT A PHOTOGRAPHER...Will have video a.s.a.p. I will try to get new video tonight of the testing that goes on adn edit it onto this post. Thanks for all of the awesome info and comments. Good luck to all.

[EDIT] 2/9/09 @ 9:00pm. Ok, no vids yet, testing was delayed to other problems, Will post asap.

Re: 2594 Robot Preview
 

Awesome idea, I can see a robot like this being in the game animation :D

can't wait to see it in action, get on that footage!

Re: 2594 Robot Preview
 

very nice:D

Re: 2594 Robot Preview
 

How tall is that robot?

Re: 2594 Robot Preview
 

54" from floor to top. bumper perimiter is 27.75"x 35"

Re: 2594 Robot Preview
 

New logo:


Old logo:



What do you think about the change? The new logo takes on the new NASKCOrpion name that we are using with this year's robot. We are still using the old design, just curious about the new one. New design is the NASKCO just for the schools. NA for NAmpa High School (the red bulldog). SK for SKyview high school (the blue hawk). CO for Columbia High School (the yellow wildcat).

[EDIT] HEY!!! TO ALL THAT WERE WAITING, THE VIDEO WILL BE UP TONIGHT, I HAVE THE FOOTAGE OF THE TUBE SHOOTING!!! YAH!!!!!!!!!!!!!!!!!!!!

Re: 2594 Robot Preview
 

FINALLY, SOME LINKS TO VIDEOS!!!

Already pointed out and answered. http://www.chiefdelphi.com/forums/sh...7&postcount=40

Re: 2594 Robot Preview
 

A little update to everyone that has been following our progress:

We took the rear drive motors off and put them on the brushes so that we can get more torque out of the final ball launching area, this now makes our robot 2 wheel drive but still four wheel steering.

We are currently building an extension piece to go on the tip of the tube so that we can get more reach on the shooting. We are setting up our programming so that we can go anywhere from sitting right on top of the trailer and barely drop the balls in to shooting around 10 feet.

New videos:

Our new site too... It is pretty good for two website designers that have never done anything related to websites before four weeks ago...

Re: 2594 Robot Preview
 

http://www.youtube.com/watch?v=xDHkYPW5RfA

for all of those people that wanted to see the 4-wheel steering 4-wheel drive in action. This video is somewhat outdated due to the fact that we are now only 2-wheel drive, but the results are very similiar. Good luck to all teams.

I know that it is blurry, it was taken on my cell phone.

Re: 2594 Robot Preview

Its amazing how much aluminum it takes before it adds up to anything......6.9 #'s ....Nice!

We mentors, teachers and students have been working to a tight schedule.

Hopefully we can get the steering problem fixed right after breakfast tomorrow morning.

Re: 2594 Robot Preview
 

Does that mean you built a practice robot or you keep it out of the crate and put in your 40 lbs?

Re: 2594 Robot Preview
 

I am not sure what you mean. But, our final robot was our prototype. After seeing everyone build their prototypes out of wood, we think we should do that next year. Then we can get some immediate results, instead of waiting for the final package to be finalized.

Here is our Team with our robot, the Skorpion. (not everyone is present)


And here is picture of our students teacher, the team coach with our robot on the night before it had to ship. Everything came together at the last moment......thanks to everyone involved!:D
