Nick,
The best I can do right now is link to our website photo album. There are a couple of good pictures that I think will show how the intake system works.

Basically, it's similar to how teams picked up balls in 2010. The front roller grabs the ball and pulls it into the lower bar and the rear roller. This picks the ball off the ground, so we can continue to move around and collect balls. The rear roller is un-covered PVC which allows it to spin on the ball when the ball hits against the bumper. Both rollers are connected by round belting and are spun with a 550s (which also power the wheels on the arm).
The wheels are there for traversing the barrier and pushing up the ramp, if needed.
The arm rests on the gas struts that assist the motors and have been designed to have the wheels ride about 1/2" above the ground during normal operation.
When we lift the arm to dump into the hopper, the ball is pinched between the lower bar and the rear roller. This hold the balls until we spin the rollers to drop the ball into the hopper.
PM me if you want more detailed pictures, I can send you some screen shots of the design.
