UNITREE R1 Edu U4 Humanoid Robot
The UNITREE R1 Edu U4 is an advanced humanoid robot built as a complete R&D platform for robotics, AI, and hands-on experimentation. Standing 1210 mm tall and weighing approximately 25 kg, it combines a compact, portable design with impressive agility, precision, and a full 40 degrees of freedom. The EDU U4 version expands on the capabilities of the R1 Basic and EDU U1, adding more computing power, AI algorithm support, two Dex3-1 three-finger hands with force control and tactile sensing, plus additional head degrees of freedom. The result is a powerful platform for ambitious research, simulation, and real-world robotic interaction.
Why choose the UNITREE R1 Edu U4?
- Advanced humanoid robot with 40 DoF for highly natural movement
- Two Dex3-1 three-finger hands with force control and tactile sensing
- Expansion dock with up to 100 TOPS computing power for AI applications
- Built for robotics research, AI development, simulation, and manipulation tasks
- Humanoid binocular camera, speaker, microphone array, Wi-Fi 6, and Bluetooth 5.2
- Compact, portable form factor with approx. 1 hour operating time
Advanced kinematics and natural movement
With a total of 40 degrees of freedom, the UNITREE R1 Edu U4 delivers smooth, realistic, and highly dynamic full-body motion. It can jump, run, perform handstands, and execute movement sequences inspired by martial arts. Each leg features 6 DoF, the waist has 2 DoF, each arm has 5 DoF, and the head adds 2 DoF. The robot also includes two dexterous hands with 7 DoF each. Wide joint ranges in the waist, hips, and knees make this model a fantastic choice for testing locomotion, balance, and manipulation algorithms in demanding scenarios.
Precision joint design for demanding use
The UNITREE R1 Edu U4 uses a refined joint design with internal cable routing through hollow shafts, helping improve reliability and protect mechanical components during intensive operation. Dual and single encoder configurations provide accurate position feedback, while localized air cooling helps maintain stable performance during extended test sessions. The robot’s arm payload of up to 2 kg also opens the door to a wide range of grasping and object manipulation experiments.
Two Dex3-1 hands with force control and haptics
The Edu U4 version comes equipped with two agile Dex3-1 three-finger hands designed for more advanced interaction with objects. Each hand offers 7 degrees of freedom: the thumb has 3 DoF, while the index finger and middle finger have 2 DoF each. Thanks to force control and tactile sensing, the robot is better suited for tasks that require delicate handling, precise contact, and more realistic robotic manipulation.
AI-ready platform
The EDU U4 introduces an expansion dock delivering up to 100 TOPS of computing power, making it ready for serious AI development. The platform is designed for machine learning, perception, and advanced robotics algorithms, with access to robot models, APIs, and developer tools. Compatibility with popular simulation environments, including Isaac SIM, allows you to move smoothly from virtual testing to real-world deployment.
Perception, communication, and interaction
The robot is equipped with a humanoid binocular camera for visual perception and computer vision projects. A built-in speaker and microphone array support natural voice interaction, while Wi-Fi 6 and Bluetooth 5.2 provide fast and stable wireless connectivity. This makes the R1 Edu U4 a versatile platform not only for movement and manipulation, but also for multimodal human-robot interaction.
Built for research, development, and ambitious hobby projects
The UNITREE R1 Edu U4 is a complete solution for labs, universities, R&D teams, and advanced robotics enthusiasts who want a serious humanoid platform. Its smart lithium battery with quick-mount design provides around 1 hour of runtime, and the included charger helps get the robot back into action quickly. Combined with a mature ecosystem and broad development potential, it is a strong choice for experimental robotics projects at a high level.
