Akash, you can post it there.

Thanks for sharing this!

The idea behind the pneumatics was when the robot stopped picking up balls and wanted to shoot, the pneumatics would pull the ball intake backwards, blocking the gap for the ball intake (and thus aiding the movement of balls the elevator up to the shooter.
The empty cell exchanger would work if you can get it close enough, and calculations based on robot bumper dimensions. Unfortunately, close enough was about two inches away in real world tests on the field. If there wasn't the rule prohibting expansions outside of the bumper perimeter, we could have made the fingers about two inches longer and it would have worked great.
The only reason why there aren't too many sub assemblies is because I used folders to organize parts in Solidworks and used patterns whereever possible. There will most likely be more sub assemblies in our 2010 robot, as 2009 was the first year we modeled our entire robot and was a learning experience for us.
