Big Trak (not to be confused with the new edition from 2010 called 'Bigtrak') is a programmable electric vehicle created by MB (Milton Bradley) Electronics in 1979, and looks like a futuristic kind of Sci-Fi tank or utility vehicle.
"BIG TRAK's computerized Control Center - with its intricate electronic memory - can accept complex programs of up to 16 separate commands. Big Trak can go out of the room and return to you; it can maneuver around furniture. Detailed instruction booklet (with sample programs) included."
The vehicle has an optional trailer (the BigTrak Transport trailer) accessory which could be purchased separately for $13 USD (in 1979) to pull around small objects.
