There are a lot of designs for self-balancing Rpi robots, like here:

@MatthewCroughan thinks it's easy to bolt on a webrtc screen and mic and camera on the front, which would mean we could be running a table-top, head height (for those sitting) telepresence robot to run freely across the board-room executive table.

Alternatively, one could use the gyros in an android tablet and send the signals and control inputs by bluetooth to an ESP32 motor controller.

We've got a drawer full of these, which does 2A and up to 15V for driving DC motors using a PWM over an H-bridge:

We can either use the old fashioned form-factor of the arduino, which would fit the board, or retrofit from something from something that can make a good PWM (ie not an ESP). Maybe @cheapjack with his new 555 timers could do the job of converting from an analog signal to a PWM duty cycle.
