# Backdrivable actuator for exoskeleton

## Abstract

The invention relates to an actuator, optionally for an exoskeleton, comprising a motor for providing speed and force to a reduction assembly; a two-stage reduction assembly comprising an input pulley and an output pulley; the two-stage reduction assembly configured to perform a speed reduction and a force increment; where the motor, the input pulley and the output pulley are coaxially located and/or in the same plane and/or inside each other within the actuator.
