Safety
Security researchers found a flaw in the Bluetooth setup of several Unitree robots, including the H1, that could let a nearby attacker take control and spread to other Unitree robots. Unitree later said most fixes were done.
A crash, recall, injury or investigation
What the source says
“The exploit impacts Unitree’s Go2 and B2 quadrupeds and G1 and H1 humanoids.”
What it means
H1 and H2, from Unitree Robotics, is at stage 4 of 5 on our ladder: paying customers. Safety events don't move a stage on their own, but they stay on the robot's record.
Human help: The maker hasn't said whether people help it remotely.
More on H1 and H2
- Unitree's shares started trading on Shanghai's STAR Market. It raised about $905 million.
- The US Federal Communications Commission (FCC) barred new models of foreign-made advanced robots from getting the approval needed to be sold in the US, unless exempted. Unitree said its existing robots already have FCC approval.
- Unitree showed the H2, the next version after the H1, in a promotional video. It is about 180 cm tall and weighs about 70 kg (154 lb).
- A video showed an H1 hanging from a crane during a test, thrashing about and making the crane crash, narrowly missing nearby technicians. The person handling it said the robot's whole-body control software was running while its feet were off the ground.
- Unitree sold 5,500 humanoid robots in 2025, across all its humanoid models, about a third of humanoid sales worldwide. Most went to research and education buyers.
- The H1 had a list price of $90,000 for the basic version.
