Jizvonius, how would holding the arm at it's full position - say, at a 40-50 degree angle up - be much different than holding it straight out? I understand that the torque will be a little bit less because of the angle, and the center of mass is closer to the pivot, but is it that big of a difference on a 5-foot arm?

From what I can tell it is a very sketchy thing to use the fisher-price motors to power an arm that needs to able to stop at various angles to retrieve, manipulate, and place tetras from loading stations and onto different height goals.
