NAxis HHD Actuators

Pre-Order

An all-in-one, high-performance robotic joint module featuring a BLDC Motor, Hat Type Strain Wave Gearbox, and integrated Motor Driver, specifically designed to handle high static and dynamic loads at the output through its integrated cross-roller bearings. Engineered for seamless integration and ease of use, simply connect it to the NLink Adapter via Controller Area Network (CAN) Bus connection and leverage our Software SDK to precisely control and command its movements according to your needs.
