Re: articulating arm help

This isn't quite an elegant solution, but you might consider adding a window motor to the system geared/matched to the RPM at one of your rotating joints in addition to the BB motors you're using to rotate the arm. The window motor's worm gear could help to lessen the need for the BB motors to operate at/near stall to hold your arm in place.
