The motor controller board has an onboard factory programmed PSoC style microcontroller. The raspberry Pi runs linux and a host of other mostly ROS connected software. The host talks to the Motor Controller board using a serial protocol.

We have another sensor board under development that also uses an Arm style IO intensive processor.
