RealMan Intelligent Technology Co. last week unveiled three new joint modules: the ultra-compact WHJ03, the high-torque hollow-core WHJ120, and the WHJ48V Wide-Voltage Series. The company said the new modules enable it to deliver a unified power system 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, claimed RealMan. The three new modules feature compact, integrated, and modular designs for robotics across consumer, commercial, and industrial applications, it said.
Founded in 2018, the company creates robotic arms and mobile robots that cater to retail, food service, commercial services, inspections, healthcare, education, aerospace, and industrial production.
Inside the three new joint modules
The first new module is the WHJ03, an ultra-compact, precision control module. It is a 3 Nm joint module measuring just 33 x 48 mm (1.2 x 1.8 in.), designed for desktop robots and consumer humanoids where space is at a premium.
The WHJ03 delivers 35% to 55% higher torque within the same volume and reduces size by more than 50% compared with mainstream alternatives, claimed RealMan Robotics. Featuring minimal backlash and low jitter, the WHJ03 provides smooth and precise motion for delicate tasks such as liquid handling and fragile object manipulation, while also supporting natural humanoid head and neck movements, it said.
Next is the WHJ120, which features a high-torque, hollow-core design. It delivers a rated torque of 120 Nm with a 16 mm (0.6 in.) hollow core, making it suitable for force- and power-limited robots and humanoids that require high torque and flexible cable routing.
The WHJ120’s hollow-core structure reduces mechanical complexity while supporting heavy-duty operations, asserted RealMan. Typical applications include shoulder, elbow, and waist joints in cobots, as well as shoulder, hip, and knee joints in humanoids, enabling compact designs capable of handling larger payloads.
Finally, the WHJ48V is part of RealMan’s wide-voltage series. Supporting input voltages of up to 60V, the WHJ48V Series delivers higher peak speeds, greater power density, and improved energy efficiency, while reducing current, heat generation, and cable losses.
Fully compatible with 24V systems, the series is well-suited for high-end humanoids, mobile robots (including quadrupeds and wheeled platforms), cobots, and exoskeletons. Beijing-based RealMan said it meets stringent requirements for dynamic response, endurance, and lightweight design.
RealMan address shortage of real-world data
Earlier this month, RealMan Robotics announced the open-source release of RealSource, its high-quality, multi-modal robot dataset. The company said it designed this dataset to address the industry’s shortage of fully aligned real-world data.
The dataset is built entirely on 10 real-world simulated environments within the company‘s Beijing Humanoid Robot Data Training Center. Opened in August, this training center brings together core technology R&D, scenario-based application testing, operator training, and ecosystem collaboration.
In October, RealMan debuted its RealBot Embodied Open Platform for teleoperation, real-time collaboration, and humanoid development at IROS.
