IS THAT A PENGUIN SWERVE DRIVE I SEE THERE?
what a wonderfully, beautifully, elegantly designed robot! does your helix roller idle against the ball with those brushes, like 148's does? wonderful robot guys!!

woah I didn't know they left the tags on the orbit balls, I would think they would be ripped off.

lol nice job. Amazing there was a team like that at the pittsburgh regional. They had an amazing robot. Nice drive train and wiring guys.

lol... i would expect them to rip em off too!:ahh:

Yes it is swerve drive! In the past we have gone exclusively with 6-wheel dropped center chain drive, so a belt-driven swerve drive has been a real learning experience. I was the one tasked with modeling the drive module in solidworks, it took about 12 hours to finish, and is composed of about 30 different parts.

As for the brushes, the core does stop spinning when we are not collecting or shooting. It saves power, and the brushes have enough friction to keep the balls from rolling back down.

Here are a few pictures that our friends on team 1726 took of our robot. The second-to-last one is my beautiful wheel module.

Thank you for your kind words

you guys where amazing at LA and where a crazy chalange to play against in the finals. I cant wait to play you guys again next year!

Nice robot, can we get a pic of your intake rollers also?

Re: pic: 1717 Fills a Goal
 

Oh and do you have a kicker roller that leads balls into your shooter

Re: pic: 1717 Fills a Goal
 

I just uploaded a shot of them picking up a ball on the practice field. Keep an eye out for it.

Re: pic: 1717 Fills a Goal
 

Yeah, it is a lexan roller with tread on it, FP motor I believe with a planetary transmission.

Re: pic: 1717 Fills a Goal
 

Here is another picture of the lower part of the robot, showing the intake roller and brush assembly. I should have spent more time to get better pictures...oh well....

I took a video of Team 1717 during their practice in the pit.
(I hope you guys don't mind that I posted this. I was definitely impressed by your drive system and had to show some colleagues of mine)

That robot is absolutely beautiful!!! IMO that is the best looking robot this year and possibly ever in FIRST

Re: pic: 1717 Fills a Goal
 

Thank you very much, this means a lot coming from 1771. You guys have a great looking, black, helical, turreted robot too. We teams with the numbers 1 and 7 have a lot in common. Your laser chassis is pretty impressive as well. My fellow students in the machine shop had to work pretty much constantly to turn out the hundreds of parts in time to go to anodize during the build season. The robot ended up looking great.

Thanks again, hopefully we will see you in Atlanta.
