Robby the Robot is a wheeled robot who can be controlled remotely or move around autonomously.
He consists of 4 motors, an L293N dual H-Bridge motor driver, an ESP32 Wifi microcontroller for brains and a rechargeable 7.4v lipo battery.
For moving autonomously his sensor package varies, but usually he will have 1 or 2 sonar sensors to detect obstacles.
