The most important part of any robot arm is actuator (servo, servo motor). And the most important part of any actuator is a gearbox. In this video I tried to develop the cheapest gearbox possible: there are only 3D printed parts, screws and nuts. There is no any bearings or other metal hardware, which makes it light and inexpensive.
All 3D printable files are available for my 10 USD/month (and higher) Patrons ([ Ссылка ]
).
Special thanks to my special Patrons: Matthew Harrison, RobotDigg Shanghai and Shounak Bhattacharya!
