Cool school robot project for dis-infecting rooms

The author make a robot that goes around with UV light and can be turned on/off remotely to dis-infect a room. Nice build with mostly standard parts. It uses 2 Micro:bits (one for the robot, one for the remote) to control it and move around. Oh and ALOT of batteries. The instructions could use a bit more fleshing out, but the general idea is there.
