To control the motor, [Gerald] is using an Arduino Nano coupled with a ULN2003 Darlington array which live on a routed PCB he made with his school’s Qbot MINImill.

In terms of the hardware, this robot uses an Arduino Nano as the brain, two motor drivers to control the DC motors, a wireless transceiver module to receive signals from the transmitter device ...
