CubeMars’ official feature on the AK70-9 and AK80-9 V3.0 makes a simple pitch: compact, powerful all-in-one modules for smooth motion, high torque and precise position control - aimed at robotic joints, medical devices and advanced automation.
What the Video Shows
The video presents the two actuators as a matched pair of modular building blocks: integrated motor, gearbox, encoder and driver in sealed housings, sized for joints where reliability and clean integration matter more than customization.

Engineering Context
MedTech brings constraints that generic industrial servos handle poorly: clean integrated housings, quiet operation, and control loops smooth enough for patient-adjacent motion. A 9:1 planetary stage in both units keeps the modules short, which helps when joints must stack into a compact kinematic chain.
