Walking Gear Robot

https://youtu.be/jNjbDgXy1e8 The Walking Gear Bot expertly converts simple rotation into a walking motion through the clever use of planetary gearing. It uses a single powerful 6V electric motor equipped with an efficient speed reducer, which can be purchased on eBay for less than $5. You will also need four AA batteries, two jumper cables or wires, and a paperclip. No soldering is required. Watch this robot walk by viewing the video. This mechanism consists of 11 precise involute gears and 36 printed parts overall.

While in operation, keep away from little children as their fingers can be caught in the moving parts and cause minor injuries. Print Settings Printer Brand: MakerGear Printer: MakerGear M2 Rafts: Yes Supports: No Notes: We cannot stress it enough -- for smooth operation, all the gears must be printed on a raft. These involute gears are designed with mathematical precision. If they are printed directly on a heated platform, they melt a little and no longer mesh well with each other. The Walking Gear Bot is built around complex involute gears. We have created this video tutorial to show you how to design precise involute gears in Blender 3D. The robot uses five strong 16-tooth gears, four sturdy 24-tooth gears, and two robust 36-tooth gears.
