About AK80-9 V3.0 Robotic Actuator

AK80-9 V3.0 packages the motor, planetary reduction stage, position sensing and power electronics into a single joint module. The integrated driver accepts commanded position, velocity or torque through its communications interface and closes the control loop locally. Its 9:1 transmission increases output torque while retaining the backdrivability and compact dimensions required for legged robots and wearable mechanisms.

Robot builders mount the actuator directly into structural joints and coordinate several units from a central controller. MIT control mode supports combined position, velocity and torque commands for dynamic motion, while standard servo modes cover conventional joint positioning. CubeMars sells the actuator with cables, control documentation and integration accessories for research prototypes and low-volume robotic systems.
