So the new bidirectional 10A speed controller arrived this evening. A quick soldering job to fit it in (and a burnt fingernail), the arm now works as I hoped it would though there are still question marks over the arm length/forks required. The video below is Shu! flipping 400g of steel right at the very end of the arm, which needs a bit of reshaping to make it more flush with the floor.
Replaying the video in slow motion, I think I may swap out the 67:1 motor for a 131:1 motor simply for the extra torque. Once the shell is completed, I'll be disassembling the entire electrical system and reposition the LiFePO4 batteries to the back of the robot for extra counterbalance.
