What and Why

PulleyDrive is a side project exploring speed reduction/torque amplification using the principle of pulleys. This project was supported by the “ProjXpo” program under MIT Innovation Initiative.

Previous Works

This work was mainly inspired by the cable-pulley based actuation of the Ambidex robot [1]

What makes it special

  1. Zero Backlash
  2. LightWeight
  3. High Stiffness
  4. Not Expensive
