China's NeodraDynamics shows a 4-metre hydraulic humanoid rated to lift 500 kg

NeodraDynamics, a Beijing startup founded in 2024, put its Neo1 humanoid on show at the China International Industry Fair: a 4-metre, roughly 1.2-tonne machine with 41 degrees of freedom, 39 of them driven by small hydraulic cylinders and two by electric motors in the forearms. The company rates each arm at 300 kg and the pair at 500 kg, gives the five-finger hands 500 kgf of grip force and a 1.7-metre working radius, and says partner JD Industrial will put the robot into its supply chain and industrial sites to test how it performs.

The bet is that the heavy end of industrial work wants hydraulic force density rather than the electric precision most humanoids are built around. Boston Dynamics moved its Atlas to electric actuators; NeodraDynamics argues what the industry retired was an old control paradigm, not hydraulics itself, and that its micro cylinders weigh about 1.1 kg each while moving loads measured in tonnes. That claim is only as good as the tolerances, which the company has published three different ways: its September release states fingertip repeatability of ±0.05 mm, its fair material says 0.005 mm, and its own product listing says 0.01 mm.

Three precision figures without a common measurement basis

The three figures are not directly comparable: the materials do not establish a common measurement basis or say which motion, measurement point or load each describes. They therefore do not demonstrate a tenfold performance difference under the same conditions. The 500 kg payload is a two-arm rating on a body that weighs 1.2 tonnes, so the robot is not carrying its own weight in the way a smaller humanoid does.

The jobs it names are not humanoid-shaped

Neo1 is aimed at what the company calls "4D" work — dangerous, dirty, dull, difficult — with a claimed operating range of −50 °C to 250 °C and use to 10,000 metres of depth: nuclear maintenance, mining, port handling, deep-sea repair, disaster debris, high-altitude construction. Those jobs exist and are dangerous. Most of them are done today by cranes, excavators and teleoperated machines that lift far more than 500 kg and need no humanoid form to do it, so Neo1's real competition is heavy equipment, and its case has to be that arms with fingers add something a crane cannot.

The next checkpoint is the JD Industrial testing. If a hydraulic humanoid can hold a precision figure during a measured industrial task, the specification sheet stops being the story.
