Walking Gear Robot

https://youtu.be/jNjbDgXy1e8

The Walking Gear Bot, through the clever use of planetary gearing, converts simple rotation to a walking motion. It uses a single 6V electric motor equipped with a speed reducer. This motor can be bought on eBay for less than $5. You will also need 4 AA batteries, a couple of jumper cables or wires, and a paperclip. No soldering required. See the video to watch this robot walk.

There are 11 involute gears in this mechanism, and 36 printed parts overall. Here is the full list of parts: quantities and filenames:
