Robot Arm Gearboxes

The next series of posts will be a catch up of the last year or so, trying to cover some of the experimenting I’ve been doing with 3d printed gearboxes for a robot arm.

This will include…

• Harmonic,
• Hypocycloidic, and
• Swiss joint (not really a gearbox)

The key requirements for gearboxes for my robot arm are…

• zero (or minimal) backlash
• high reduction ratio
• compact size
• low weight
• easy to make
