High Performance Actuators
IHMC’s High Performance Actuators are powerful, light, and transparent, giving robots the (degrees of) freedom to do extraordinary things. Available in a range of sizes, there’s one for every use case.
Take a look inside.
Cycloidal Transmission
Strong. Safe. Silent. Each actuator is driven by a brushless DC motor and in-line cycloidal transmission. This affords our actuators quasi-direct drive performance at high gear ratios, low backlash, high torque density and efficiency, low backdriving torque, and resistance to impact.
Durable Construction
Highly athletic motion = high internal forces. Featuring numerous steel retaining features and high-load bearings, these actuators can take a beating and keep running strong.
Speed and Power
Dynamic on demand. Our actuators can supply high power and high precision, Useful for door opening, manipulating objects, human-speed walking, and martial arts. All of which have been tested on Alex.
