Compared with other buggy designs, Trekker's makers concentrated on speed of roaming by swapping the usual stepper motors for dual, geared induction motors to help it get around.

As well as a pen slot, Trekker boasted obstacle sensing via 'bump sensors' that looked like an insect's feelers, an LDR light sensor, white line follower, beeper and nose mounted reed switch for magnet detection. It also looked racier than most of its contemporaries with its shape owing more to radio controlled cars than turtles or robots.

Its brain is a BBC Micro Computer which is attached by a long ribbon cable. The cost in 1985 was £139.95
