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
