Compliant Actuators

Updated: Jan 31, 2022

HASEL actuators from Artimus Robotics offer soft, compliant motion. They can be manipulated, bent, twisted, and conformed to a fixed available space and still operate normally.

Traditional electric actuators are made from metal components and offer no compliance. Metal actuators have an uncompromising rigid structure that requires a specific form factor to operate. If an object interferes with the motion path, the traditional actuator will usually fail catastrophically. The motion provided is also hard and insensitive, resulting in damage when actuating delicate objects.

HASEL actuators provide lifelike motion and are perfect for actuating in delicate environments. The structure is soft and forgiving, allowing compliance in tight form factors or unusual geometries. Additionally, HASEL actuators are robust, despite their delicate movements. They can be bent, twisted, or interfered with and still actuate their normal behaviors.

About Artimus Robotics

Artimus Robotics designs and manufactures soft electric actuators. The technology was inspired by nature (muscles) and spun out of the University of Colorado. HASEL (Hydraulically Amplified Self-healing ELectrostatic) actuator technology operates when electrostatic forces are applied to a flexible polymer pouch and dielectric liquid to drive shape change in a soft structure. These principles can be applied to achieve a contracting motion, expanding motion, or other complex deformations. For more information, please visit Artimus Robotics or contact
