Product overview
About Unitree H1-2
The Unitree H1-2 is a full-size biped humanoid of about 178 cm and 70 kg. Unitree's H1/H1-2 product page lists it with 27 degrees of freedom: seven per arm and six per leg. Each arm is rated for about 7 kg, with a peak of about 21 kg, and the page gives a moving speed below 2 m/s.
Hands are optional, and Unitree names the Dex5-1 as one option. Power comes from a 15 Ah, 0.864 kWh pack with a 67.2 V maximum voltage. Compute is an Intel Core i5 platform computer, with an Intel Core i7 for user development and optional Orin NX modules, up to three devices in total. A Vietnamese national AI database reports about 2 hours of runtime and a swappable battery; Unitree's page does not state runtime.
The product page gives no price, and the H1-2 is not listed on Unitree's shop. Sales and cooperation inquiries go through Unitree's booking page, and an authorized distributor lists the H1-2 as in stock.
