Compliant Actuators

We are integrating actuators with humans

ECS - Equilibrium Controlled Stiffness

Control the input side of the spring to adjust the virtual stiffness and pre-load force

We designed a robotic tendon actuator for powered prostheses and orthoses

Equilibrium controlled stiffness

Adjust the structure of springs to change the stifness properties

A nut is actively driven into the helical pattern of coil spring. The spring stiffness and length are both adjusted at the same time.
