Weihan Power

北京微悍动力科技有限公司

Weihan Power, registered as Beijing Weihan Power Technology Co., Ltd., is a wholly-owned subsidiary of RealMan Intelligent Technology (Beijing) Co., Ltd., also known as Rui'erman, established around September 2023 as RealMan's dedicated core-components arm for robot joint actuators, with a stated target production capacity of roughly 50,000 units per year and reported openness to raising independent financing in the future. The subsidiary is based in Beijing.

Weihan Power's product focus is high-power-density integrated joint modules for robot actuation. An earlier generation of its modules achieved CR L3 safety certification and a rated mean time between failures of 50,000 hours, while reducing size and weight by 30 to 50 percent compared with conventional joint designs and delivering torque the company describes as at least double that of comparable products. In January 2026 the company introduced its HPD series of integrated joint modules, built around what it calls a hat-type structural design combined with reinforced torque transmission and an ultra-thin hollow shaft layout. The HPD series delivers an average torque improvement the company puts at around 30 percent over prior designs, carries a rated operating lifespan of 10,000 hours, spans a size range from industrial-scale joints down to dexterous-hand base joints, and supports customer-specific interface configurations. The company positions the HPD line for use across industrial robots, collaborative robots, humanoid robots, and other high-precision equipment.

Weihan Power's joint modules have been demonstrated in a range of RealMan-affiliated robot applications, including a tea-serving robot built on RealMan's RealBOT wheeled-humanoid platform, a W1 unmanned warehouse storage system designed for continuous 24-hour operation, and an AI-guided massage robot that combines visual positioning with force sensing. As a component supplier operating inside a robot-arm and cobot manufacturer's corporate structure, Weihan Power occupies a similar niche to other Chinese joint-module makers spun out of robot-body companies to supply both their parent's product lines and third-party robot builders with actuator hardware.
