BIG TRAK (US) or Bigtrak (Europe) was a computerised toy vehicle created by Milton Bradley in 1979. This six-wheeled tank-like monster came with attractive decals, a front-mounted blue photon beam headlamp and an integrated programmable keypad that remembered up to 16 commands which it then executed in sequence. The US version was moulded in grey plastic while the European version was white. A companion unit was sold separately – the Big Trak Transporter – a trailer which could be attached to the rear that carried and dumped loads in response to Big Trak’s pre-programmed commands. Big Trak was relaunched in 2010 by Zeon Ltd who produced replicas of the original.
