Cole and Gabriel finished the PC board to control each joint of the legs. They tracked down the problem to a MOSFET that was backwards. Easily fixed, and after that the board worked perfectly. They also installed the new two and three pin connectors that came in. Here’s the completed board – a fine piece of work!
On the left is valve assembly that will be used to drive one leg. There are 4 valves total in this assembly, two for the knee and two for the hip.
