Young humanoid wanted to work on his
MPMA series. He decided that if both tracks could only rotate forward but were powered by one motor each, he would have a robot that could turn but still have dual-motor power. To accomplish this, he directed each motor into a differential unit. The second output for each of the two units cycled a pneumatic switch. The third motor was attached to a floating worm gear (thanks to TooMuchCaffeine's design) which powered three pumps with one output, and a third switch with the other. MPMA V2 was disappointing. Its base was weak, it was not very maneuverable and its compressor was slow (possibly due to a damaged motor). Young humanoid never implemented a use for the third pneumatic switch.
