The machine in motion
What it is
The H1 is a full-size two-legged robot made by Unitree, a Chinese robot maker. Unitree calls it its first general-purpose humanoid robot. The company says it stands about 180 centimetres tall and weighs about 47 kilograms.
Each leg has five powered joints, each arm has four. Unitree says the arm joints can be extended. The robot carries a three-dimensional laser scanner, called LiDAR, plus a depth camera for seeing its surroundings.
What it can actually do
Unitree lists a moving speed of 3.3 metres per second. The company labels this a world record and says the hardware could pass 5 metres per second. Independent reports say Guinness World Records accepted the 3.3 figure for a full-size humanoid robot.
The joints are strong for a machine this light. Unitree gives about 360 newton metres at the knee and about 220 at the hip. Ankle joints reach about 59 newton metres and arm joints about 75.
Two Intel processors do the thinking in the standard build. A Core i5 runs the platform and a Core i7 is left for the owner’s own software. Unitree offers other options, including an Nvidia Orin NX module. Gripping hands are an extra, not standard.
Where it stands
Unitree sells the H1 through its own online shop. The listing shows 90,000 US dollars and asks buyers to contact sales for the real price. Customs duties are not included.
When the robot was first shown in August 2023, trade press reported a target price below 90,000 US dollars. The buyers are research groups, universities and companies building their own software. Unitree’s own page warns that the humanoid field is early, and advises private buyers to learn the limits first.
A second version, the H1-2, sits on the same page. It is about 178 centimetres tall, weighs about 70 kilograms and has 27 powered joints. It moves slower, under 2 metres per second, but its arms are far more capable.
What is unclear
Unitree publishes the battery size, 864 watt hours, but not how long one charge lasts. It gives no carrying capacity for the H1 itself. Arm load figures on the page apply only to the H1-2.
Sales numbers, delivery times and support outside China are not published. Unitree also notes that the shipped robot may look different from the website pictures.
