It is possession people just refer to it as dribbling as the inspiration came form this video for most http://www.youtube.com/watch?v=K3Nb9NAxdeE

Hmm. A banebots RS-545 (just for testing; we know it's not 2010 legal) to a 4:1 transmission with 16:22 sprockets, so ~3000 RPM -- at a 2.5" roller diameter, this is roughly 3 feet per second faster than our drive train.

This (intake mechanism worksheet) may help.

We want to have both options in the event that we're dribbling one ball and going in the direction of another. Thus we'd avoid possessing two balls at once. We feel this will inadvertently happen more than one might expect.

Re: Roller/Gatherer Test

Well, if the roller can't keep up with the drive train, then you'll never keep the ball close to your bot as you drive away from it.

We're doing the same thing but with PVC pipe instead of a pool noodle.

You guys all realize your final mechanism has to be inside your frame, right? See <G30>.

The noodle fuzz? Yea, we know. Just thought I'd give you a heads up about it.

Re: Roller/Gatherer Test

Yes, like stated in my first thread, just a test bot, once put into actual robot it will be inside the frame

I am aware of that rule. I'll show you guys a blueprint of sorts if you would like to see it.

That one's easy ... the roller's inside the frame no problem. On the field, back up to a ball and spin the roller so that the ball has a back spin, then keep the roller tip at the same speed or greater than the drive train as you drive in the opposite direction.

Just checking. It's really a downer for an inspector to have to not allow a robot to compete.

Re: Roller/Gatherer Test

That works amazingly! Have you tested to make sure you can't have possesion of 2 balls at a time?

Re: Roller/Gatherer Test

well thats mostly from drivers ability, but i do believe that 2 balls might not fit but we would have to check that tomorrow
