As I expand my horizons with Charlie, I am thinking about using other sensors or such like with him. Additional bumpers? Another distance sensor, or something else?
Looking at the PivotPi PCB, it looks like a board that, more or less, provides a lot of additional connectors to interface with various devices, servos and such like.
Is the Pivot Pi compatible with the GoPiGo-3 - that is, can I stack them and get the best of both worlds?
