It was a six-wheeled tank with a front-mounted blue photon beam headlamp, and a keypad on top. The toy could remember up to 16 commands which it then executed in sequence (such as "go forward 5 lengths", "pause", "turn 30 degrees right", "fire phaser" and so on. There was a "repeat" instruction allowing simple loops , but the language was not Turing complete , lacking branching instructions; the Big Trak also lacked any sort of sensor input other than the wheel sensors. There is now a small but dedicated Internet community who have reverse engineered the BIG TRAK and the Texas Instruments TMS1000 microcontroller inside it (see external links). The US and GB/European versions were noticeably different. The US version was moulded in gray plastic and labelled BIG TRAK whereas the GB version was white and labelled bigtrak with a different keypad. Bigtrak also included an optional trailer accessory. Once hooked to Bigtrak, this trailer could be programmed to dump its payload. Soviet clone In the Soviet Union , a clone was made under "Elektronika IM-11" designation. The early production version was named "Lunokhod ". It featured an obstruction sensor disguised as a plastic front bumper, which would stop the program when the toy got stuck. However, there was no provision for an accessory, and its motion sensor was based on a cheaper reed switch instead of an opto-isolator . A later version, named "Plane...
