Re: pneumatic cylinders and motors with wires
 

I'm worried about your cylinders bending. If a robot traveling 15 fps comes crashing into your arm, do you think the cylinder will survive?

I predict many broken attachments this year.

when the arms are not being used the arms are in the frame and up.

Right, but when they are "being used" is exactly when you'll be attracting the attention of the aggressive defenders.

At a minimum, it would appear to be a relatively straightforward change to put the gear motors on TOP of the ball rollers instead of down at the bottom. They might have a better chance of survival up on top. That is...IF there isn't some kind of space constraint in the retracted position with the motors on top.

Alternative: Bring 45 pounds of extra ball collectors. You'll need them.
