This toy was inspired by the Odd Rods stickers of my youth:

This is a single motor 2 function remote controlled toy robot. It can move forward or spin in place for steering. It is a modified version of this design:

The wheel base is slightly longer so it has tracks with more sections. The internal parts are the same except for the frame.
It is controlled by the transmitter and receiver from a Coke can RC car. It uses a yellow TT motor with dual shaft output. It is powered by 3 AA batteries. The hardest part of the build is the electronics.
The parts that have to turn freely on 3mm screws will probably need to be drilled out with a 3mm or 1/8 inch drill. The 3mf file is a Bambu studio project file for the multi colored head.
The tracks are print in place.
Hardware needed:
Coke can RC car
The hardware required is 3MM screws of various lengths:
