Unitree R1 Robot
The new R1 series, designed for research, education, and development, offers advanced mobility and intelligence in a more accessible form factor. EDU models include a powerful add-on computer for demanding projects.
The agile design provides impressive movement capabilities—from 24 to 26 degrees of freedom (DOF). The robot's design allows for a wide range of maneuvers, providing a solid foundation for implementing specialized functions and processes. The Unitree R1 is integrated with large, multimodal visual-lingual models and offers full access to control interfaces for both joints and sensors.
The R1 EDU series features enhanced articulation and research-grade features:
R1 EDU (U1)
R1 EDU (U2)
R1 EDU Pro A (U3)
R1 EDU Pro B (U4)
R1 EDU Pro C (U5)
R1 EDU Pro D (U6)
What are the differences between the R1 robots?
The Unitree R1 Basic is a compact humanoid robot measuring 127 cm in diameter and weighing 35 kg, designed as an entry point into humanoid robotics. It features dual 3D LiDAR, depth cameras, and agile motion control, providing a robust platform for education, demonstrations, and fundamental research in locomotion and perception.
The EDU variants expand upon the basic R1 model. Like the G1 EDU, it includes a second computer for development, with 40 TOPS (Trillion Operations Per Second) for the R1 EDU U1 or 100 TOPS for the EDU U2 to U6.
