The proof of concept is built using a toy car that is designed to adhere to walls and ceilings. 

The circuits and battery were removed.  An MX1508 motor driver and Arduino pro mini are wired in with external power to enable autonomous motion.

The next step will be to add  VL53L0X lidar to add logic to it's movements and a  battery that supplies enough current for the motor drivers but is not so heavy that the negative air pressure cannot support it.
