Worker M1, or 劳动者 M1, is what Gelanruo calls the industry's first fifty-kilogram-class heavy-load humanoid, and the whole design follows from that one number. It stands 187 cm and weighs 86 kg so that it can carry 50 kg in its two arms, and the company is careful about what carrying means at that load: robust load-bearing walking, coordinated dual-arm torque output and dynamic load posture compensation, which is the part that keeps a machine upright when the mass it is holding shifts. The joints are integrated high-output units with load-impact buffering, efficient thermal balance management and large instantaneous torque, peaking at 430 newton metres, and every joint carries dual encoders to keep arm end accuracy at 1 mm or better even under load. Safety is treated as a system rather than a feature: hardware-level redundancy, fault self-diagnosis and alarming, and millisecond emergency braking. The published joint ranges cover the waist at minus 90 to plus 90 degrees, the hip from minus 45 to plus 90 in pitch and minus 35 to plus 90 in roll, a knee with a minus 35 to plus 35 axis plus a 0 to plus 110 axis and an ankle from minus 55 to plus 30 in pitch. It moves at above 1.2 metres per second on a 22 Ah battery good for two hours, and the company positions it on real industrial working conditions with open secondary-development interfaces and multi-industry customisation. One caveat worth knowing when reading the company's own specification table: its C1 column repeats M1's numbers exactly, including the 50 kg payload, which is physically impossible for the 38 kg C1, so the heavy-load figures belong here and only here.
