RealMan Robotics Launches Next-Generation High-Power-Density Joint Modules

RealMan Robotics has unveiled three next-generation joint modules: the ultra-compact WHJ03, the high torque hollow-core WHJ120, and the WHJ48V Wide-Voltage Series. This launch marks a key milestone in the company’s strategic expansion in core robotic components, delivering a unified power solution for robots ranging from lightweight desktop arms to heavy-duty industrial systems. The High-Power-Density (HPD) servo joints deliver high torque density, fast dynamic response, high precision, reliability, and cost efficiency. These three new modules address diverse industry needs through compact, integrated, and modular designs, enabling high-performance robotics across consumer, commercial, and industrial applications.
WHJ03: Ultra-Compact, Precision Control
The WHJ03 is a 3 Nm joint module measuring just 33 x 48 mm, designed for desktop robots and consumer humanoids where space is at a premium. It delivers 35-55 percent higher torque within the same volume and reduces size by more than 50 percent compared with mainstream alternatives. Featuring minimal backlash and low jitter, the WHJ03 ensures smooth and precise motion for delicate tasks such as liquid handling and fragile object manipulation, while also supporting natural humanoid head and neck movements.
