Unitree R1 Ultralight Agile Humanoid Robot
25kg, 1.21-meter ultralight humanoid robot packing 26 high-torque QDD joint degrees of freedom (expandable to 40-DoF), binocular depth vision, and whole-body reinforcement learning agility.
Key Engineering Highlights
- Breaks the $6,000 price barrier for a full-body 26-DoF bipedal humanoid platform
- 25kg low-inertia frame executes continuous cartwheels, handstands, and rapid push-recovery out of the box
- Upgradable to 40 total DoF with multi-finger dexterous hands and 100 TOPS onboard edge compute
