This linear actuator is designed for linear joints on humanoid robot limbs. It integrates drive system, transmission structure, force sensing and position feedback as a single unit, equipped with large-lead planetary roller screw, four-point contact bearing, high-performance frameless torque motor, high-precision inductive encoder and high-precision tension force sensor.
-
High Thrust Density
It provides a maximum thrust of up to 8 kN with compact and lightweight dimensions, meeting the weight reduction demands of humanoid robots.
-
Dual Full Closed-Loop Sensing
Position and force dual closed-loop control enables precise flexible motion, landing buffering and external force detection.
-
Highly Integrated Monolithic Structure
The motor, screw, sensors and bearings are entirely encapsulated inside the cylinder, simplifying wiring layout and improving overall assembly efficiency.
-
Superior Dynamic Response
The combination of frameless torque motor and large-lead screw delivers fast extension and retraction, suited for high-dynamic gaits including walking, running and jumping.
-
Shock Resistance & Durability
The planetary roller screw paired with heavy-load bearings withstands impact loads from robotic gaits, extending the service life of the whole actuator.
