Re: FIRST Team 2980's 2012 Open Source Robot

Cool thread, I'll be following your build progress!

I'm curious, what kind of shop and manufacturing capabilities do you have available? Using the first stage out of the plastic FP gearbox in the kit of parts is an easy workaround for not being able to buy AM planetaries if you have the ability to manufacture transmissions. Here's an example.

I would echo this statement... you can run into a lot of problems if you rely on gravity/momentum to move a game piece. We have a rule for our design team this year: the ball must be compressed against a roller/belt at all times when it is in the robot. That's not to say your design won't work, but you want to make sure you test it enough to ensure it is reliable and won't get jammed.

Highly recommended! Try to get a quick prototype set up for some of the ideas you're not certain about to see if they'll work.
