Fifty plus years ago I received a toy car for Christmas that had one electric motor powered by two D cell batteries. While the electric motor drove the rear wheels to propel the car forward, the car also included a unique steering system using a gear driven rotating "cam" which steered the car in a geometric path. The car came with a variety of cams, and by changing the cam, the car would travel a different path.
The car has long since disappeared and I could not locate another, so in today's world of micro controller and servo / stepper motor driven vehicles, I thought I would recreate my decades old electric motor driven / cam steered toy car in 3D printed form entitled "Robotic Cam Steered Vehicle" for the kids, grandkids, and of course, me!
Unfortunately, Thingiverse is still broken, but this model is available at the following locations:
Designed using Autodesk Fusion 360, sliced using Cura 4.4.0, and printed in PLA on an Ultimaker 3 Extended and an Ultimaker S5.
One final note, I receive no compensation in any form whatsoever for the design, equipment, parts and/or materials used in this model.
