Unitree H2
Unitree H2 is a bipedal robot with 31 degrees of freedom.
Summary
The Unitree H2 is a bipedal robot with 31 degrees of freedom, designed for research, education, and entertainment applications. It can walk at 1.389 m/s and climb stairs.
The Unitree H2 stands 180 cm tall, is 45.6 cm wide, and 21.8 cm deep, with a mass of 70 kg. It features 31 degrees of freedom, with 6 per leg, 7 per arm, 3 at the waist, and 2 at the head. The robot is constructed from aluminum, plastic, and titanium, and uses PMSM actuators with air cooling. Its power system includes a 15 Ah li ion battery with 972 Wh energy, supporting 180 min of runtime. The compute unit is an Intel Core i5, providing 2070 TOPS of AI compute. Navigation is performed using vslam, and it supports voice interaction with 4 microphones.

Specs
79 of 195 measures disclosure, not the robot: it counts the specs the maker and the directories we read had published when this page was last checked, so a robot with fewer published specs is not a worse robot. Makers also measure differently — height with or without the head, payload rated or peak — so two sources can both be right and still disagree, which is why every value carries a chip naming who stated it.

No value below has been independently measured or filed with a regulator — every number is a claim by the maker or by a third-party directory, and the chip on each one says which.

[statement 6abb5ab7b02736b83e920109] an OPTIONAL Jetson AGX Thor module offered on the EDU variant, not this robot's own AI compute — the same page states H2's compute is PC1 (Intel Core i5) and PC2 (Intel Core i7), and that row's NOT text forbids an accessory's figure — review-flagged, then judged against the page context around the quote.
