https://youtu.be/D4A8Wu-qiP8.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!
