Calvin: a differential drive balancing robot.
Calvin is a work in progress. This site offers a view into the development progress involved in his creation. He's taught me a lot. Maybe you'll learn something too.
Development Log & Notes
A log of the work, along with some notes.
Engraving Plastic
Making label plates for Calvin's power switches with an engraving bit and a lot of trial and error in Fusion.
Chassis Parts
Machined motor plates, pressed bearings, and a new filament to solve the warping problem on the printed frame.
Printing Jigs
The frame was out of square because I tapped the holes by hand. A couple of printed jigs fixed that.
