In this video, we showcase the real-world application of the CubeMars AK80-6 KV100 robotic joint module in a cutting-edge academic research project. The research team at Georgia Institute of Technology (Georgia Tech) utilized the CubeMars AK80-6 KV100 quasi-direct drive actuator as the core power source to successfully develop an advanced bilateral exoskeleton robot. The system is designed to provide smooth, precise, and efficient power assistance for rehabilitation and human mobility enhancement.
Exoskeleton robots place extremely demanding requirements on joint actuators. To achieve natural and seamless human-robot interaction, actuators must provide not only high torque density to support human movement but also excellent rotor transparency to accurately detect the user's motion intention. Traditional motors with high-ratio gear reductions often suffer from backlash and friction, making them difficult to meet the requirements of highly dynamic rehabilitation applications.
To address these challenges, Georgia Tech selected the CubeMars AK80-6 KV100 as the hip and knee joint actuator for the exoskeleton system. With the following key technological advantages, the AK80-6 KV100 perfectly matches the project requirements:
The AK80-6 KV100 adopts a low-ratio reduction design, significantly reducing system inertia and friction. This quasi-direct drive characteristic enables high force-control bandwidth, allowing the actuator to respond quickly to impedance control algorithms and ensuring smooth, safe, and natural human-robot interaction.
Despite its compact size, the AK80-6 KV100 delivers up to 15 Nm continuous torque and 38 Nm peak torque. This allows the exoskeleton robot to provide powerful assistance while maintaining a lightweight structure, reducing the metabolic cost for the user.
With a highly integrated design combining the motor, driver, and encoder, the AK80-6 KV100 greatly simplifies internal wiring and mechanical integration of the exoskeleton system, helping research teams accelerate prototype assembly and development iterations.
Through this video, you can directly observe the outstanding performance of the Georgia Tech exoskeleton powered by CubeMars actuators, including:
Gait tracking tests during user walking movements.
Smooth actuator output and rapid response under dynamic loads.
Coordinated operation of the bilateral exoskeleton system for rehabilitation assistance scenarios.
Whether for exoskeleton robots, quadruped robots, humanoid robots, or other robotic platforms, CubeMars is committed to providing high-performance miniature actuator solutions.
