The MonsterBorg Raspberry Pi robot is a beast of a kit designed to be taken off road and can be programmed as a self-driving robot, used for education about self-driving systems, or raced around the garden as an RC off-roader. It makes a great platform for hacking about with robots by adding extra sensors or servos.
The MonsterBorg kit comes with the wires, screws, motors, hubs and wheels that you need to get it running. You need just add a Raspberry Pi, a micro SD card, 10 AA batteries, and an optional Pi camera. Screwdrivers are needed for assembly.
