From August 8 to 12, 2025, the highly anticipated WRC World Robot Conference will be grandly held at the Boren Yichuang International Convention and Exhibition Center in Beijing Economic and Technological Development Zone. As an annual international event in the robotics field, this conference has attracted the active participation of many well-known enterprises and research institutions in the industry. Nous Robot brought the humanoid robot full-stack linear joint drive actuator to this exhibition, which attracted much attention from the industry.
In terms of the key components of humanoid robots — linear actuators, Nous Robot has specially developed leg and arm linear actuators with a maximum load capacity of 8000N for humanoids. These actuators adopt the same RVI reverse planetary roller screw structure as Tesla. This structure can not only greatly improve the load capacity of the actuator, but also does not generate heat under long-term high-load working conditions, enhancing its stability and durability, making it the ultimate solution for precision transmission of humanoid robots.

It is particularly worth mentioning that Nous Robot has launched the world's smallest planetary roller screw product. This screw has a diameter of only 1.5mm and a nut diameter of 5.5mm. Although it is small in size, its load capacity can reach about 10kg and its service life is up to 3 million times, making it the planetary roller screw with the largest load capacity of the same size currently. The advent of this product provides an excellent linear actuator solution for precise control in narrow spaces, effectively solving the problems of short service life of traditional rope drive, low efficiency of trapezoidal screw, insufficient link load, etc., bringing a brand-new solution for application scenarios with extremely high space requirements such as robot dexterous hands. At present, Nous Robot has become the preferred supplier of dexterous hand linear actuator solutions for several leading humanoid robot companies in China, and its product performance and quality have been highly recognized by the market.

Against the backdrop of the rapid development of the humanoid robot industry, the performance and cost of core components directly affect the development process of the entire humanoid robot industry. Nous Robot's innovative achievements have not only won market opportunities for itself but also injected strong momentum into promoting the large-scale development of China's humanoid robot industry. By participating in the 2025 WRC World Robot Conference, Nous Robot is expected to conduct in-depth exchanges and cooperation with more industry partners, jointly explore the unlimited possibilities of robot technology, and contribute Chinese wisdom and strength to the innovative development of the global robot industry.
