RealMan RM Series Arm

RealMan's ultra-lightweight humanlike robot arms, with the controller built into the arm itself.

The RM series comprises lightweight collaborative robot arms from Beijing-based RealMan Intelligent Technology, which the company markets as “ultra-lightweight humanlike arms.” Its flagship models are the 6-axis RM65 and the 7-axis RM75. Taking the B variant as an example, the RM65-B weighs about 7.2 kg, has a rated payload of 5 kg, and a working radius of about 610 mm; the RM75-B weighs about 7.8 kg, also has a rated payload of 5 kg, and repeats position within ±0.05 mm. Its defining feature is a controller built into the arm body itself, running on 24V DC power, giving it a high payload-to-weight ratio — which makes it easy to mount on a mobile base, a wheeled humanoid, or a dual-arm platform. Many Chinese embodied-AI companies and universities use it as the arm on their dual-arm or mobile-manipulator systems.

ExampleMounting two RM75 arms on a lift column and a mobile base is enough to assemble a dual-arm mobile manipulator for collecting teleoperation data.
