Turning the Big Trak into a Turtle

[Diablo]

Children of the 80s may remember the Big Trak, a six-wheeled programmable toy designed to explore distant planets on the other side of the living room and the vast expanse of a two-car garage. The Big Trak was re-released a few years ago and [Nathan] took quite a shine to this improved version. He was so enthralled he decided to upgrade it even more to support the LOGO programming language.
The 30-year-old version of the Big Trak had a membrane keypad where commands such as ‘drive forward 5 units’ and ‘turn 90 degrees’ can be saved and run from memory. This is very similar to the LOGO programming language with and turtle graphics and nearly identical to the Roamer LOGO robot.
To control the Big Trak, [Nathan] upgraded the electronics to a ChipKit Uno and a BeagleBone. A LOGO interpreter written in Python and uploaded to the BeagleBone. After this, [Nathan] was nearly set. He did add a WiFi interface to control his Big Trak wirelessly, a nice touch we think.
You can check out [Nathan]‘s twenty-minute build video where he goes through the entire process of upgrading his Big Trak after the break.
