Re: Official Team 2526 Robot Model!!
Figure out a way to brace the arm from swinging side to side too much. Turning with the ball lifted might well provide a heck of a lot of air drag causing significant problems.
A couple approaches...:
-Simple vertical rails on the side of the arms might help minimize swaying of the arm.
-Line the parts of each arm joint with aluminum plate (3/16 or 1/4, is my suggestion), and run a larger bolt size through that.
If you want help with the calculations, contact a local college with any sort of engineering at it... I'm sure you'd be able to get a professor to donate a couple hours of time doing/showing how to do the calculations to determine which cylinders you'll want.
Definitely make design changes so that you can get those arms in your starting box... You might need to be creative (but smart) with a method of having the claws start folded vertically, and then drop down and lock in place.
