Unitree R1

Humanoid Agent AI Avatar

The Unitree R1 is the most accessible full-body humanoid robot ever produced by an established manufacturer — named a TIME Magazine Best Invention of 2025. Compact, agile, and intelligently designed for human-scale indoor environments, the R1 brings genuine humanoid robotics within reach of educators, developers, and innovators who were previously priced out of the market. It walks, runs, cartwheels, recovers from falls, speaks, and responds to voice and visual commands — all from an onboard multimodal AI model.

Ideal for: University STEM education, hobbyist and developer prototyping, human-robot interaction research, public demonstrations and events, AI companion and social robotics, and entry-level reinforcement learning development.
