The boards on each arm look like they may actually take a *speed* as their input to control the motors, since they have an input from an encoder on each motor shaft (motors are missing). I wonder if these are custom boards or if they're off the shelf speed controllers. Anyone have any idea what the PC104 boards are? The top one has connectors for the controllers, which could be serial, and connects to the bottom one via a ribbon cable rather than via the normal PC104 connector, so it seems like the boards are designed to work together. Perhaps the bottom one is the main board and the top one is to break out the peripherals from the bottom one? There doesn't seem to be a lot of logic on the top board. The metal monolith-shaped thing on the far side of the top board looks like it could be a power supply. I also don't see any connections coming out of the IMU. -- Sean Lynch http://sean.lynch.tv/
