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.
This work was mainly inspired by the cable-pulley based actuation of the Ambidex robot 
What makes it special
