The Milton Bradley Big Trak (also stylised as bigtrak) is a programmable toy resembling a futuristic utility vehicle that could have been used by Moon astronauts or colonists. It has six wheels (two drive wheels), a “photon beam” headlamp and a keypad on top.
Users could program in a sequence of up to 16 commands, with multiple presses of the movement and directional directives combining into single commands, such as “move forward 10” or “turn right 90 degrees”.
