This machine would spin two threads together. It was based on the Spinning Jenny in a textile mill that my great-great-great-great-granduncle built. The mill is still in operation at Upper Canada Village.
The Rhino Charger was a commercial computer controlled industrial robot. My version had the same basic movements, but was powered entirely by hand cranks (at the time I didn't have any suitable motors). The forearm and its counter weight was so heavy that it bent the steel axle in the elbow joint. This project taught me a great deal about how not to build a robot.
