The GearBot is a simple, single actuator 3D printed toy with a transmission entirely made up of gear mechanisms. This bot includes a working clutch mechanism, along with some other basic types of gears. If you are interested in gear mechanisms, I would suggest checking out this Basic Gear Mechanisms Instructable. I hope you have fun building this, and even more fun designing your own!
GearBot is entirely driven by gear systems, which are a type of mechanical transmission. Gears are essentially circular wheels with teeth around their circumference, and the teeth mesh with other gears to transmit power. As gears rotate, their teeth contact the teeth on other gears, thus forcing the other gears to rotate as well. GearBot is a simple system composed of multiple gear systems drive the robot forward.
