In 1987 LEGO released several Activity Cards with examples to be used with the Interface A. One particular Activity Card, the 9700b8, proposed a robotic turtle that could be used to draw lines like the Logo Turtle (in fact, Interface A was used used with a LEGO variant of the Logo language) or even a lne follower!
I don’t have the exactly parts to build a 9700b8 robotic turtle but have enough TECHNIC bricks already available at that time so created my own robotic turtle… the Python Turtle 🙂
I think Dr. Seymour Papert would like this turtle.
