MaLPi Hardware Version 2

Machine Learning on a Raspberry Pi (also a subtle reference to the Stargate shows)

This was the second version of MaLPi’s hardware. Based on an acrylic chassis that came with motors for each of the four wheels. I added a Raspberry Pi and camera, along with a motor hat to control the motors.
