UNITREE R1 Edu U3 humanoid robot

UNITREE R1 Edu U3 (Crismon Hero) Humanoid Robot

The Unitree R1 Edu U3 is an advanced humanoid robot designed as a comprehensive research and development platform for robotics and artificial intelligence. With a height of 1210 mm, a weight of approximately 25 kg, and as many as 40 degrees of freedom, its design ensures very high mobility and precision of movement, while remaining compact and easy to transport. The EDU U3 version combines all the capabilities of the R1 Basic and EDU U1, expanding them with more powerful computing power, support for AI algorithms, two Dex3-1 three-fingered hands, and additional degrees of freedom for the head. All of this makes the device a complete tool for advanced experiments, simulations, and more.

Advanced kinematics and natural movement

The robot offers a total of 40 degrees of freedom, which translates to very realistic, smooth, and complex movements of the entire body. The Unitree R1 Edu U3 easily jumps, runs, walks on its hands, and even performs sequences inspired by martial arts. Each leg has 6 DoF, the waist has 2 DoF, each arm has 5 DoF, and the head has 2 DoF. On top of that, there are two hands—each with 7 DoF. The wide ranges of motion in the waist, hips, and knees allow for testing advanced algorithms for locomotion, balance, and manipulation in dynamic scenarios.

Precise joint design

The Unitree R1 EDU U3 features a refined joint design with internal cable routing within hollow axes, which enhances reliability and protects mechanical components during intensive use. The use of dual and single encoders ensures high position reading accuracy, and local air cooling helps maintain stable operating parameters even during prolonged testing. In addition, the arm’s maximum payload of 2 kg enables experiments involving grasping and manipulating objects.

Two Dex3-1 hands

The R1 robot in the Edu U3 version is equipped with two dexterous three-fingered Dex3-1 hands with force control (without touch sensors). Each has 7 degrees of freedom—the thumb has 3 DoF, the index finger 2 DoF, and the middle finger also 2 DoF. This allows the device to handle tasks requiring precise object manipulation even better.

AI-Ready Platform

The EDU U3 version introduces an expansion dock offering up to 100 TOPS of computing power. The platform has been designed with intensive development of AI algorithms, machine learning, and perception in mind, offering ready-to-use algorithmic support and full access to robot models, APIs, and developer tools. Added to this is compatibility with popular simulation environments, including Isaac SIM, which enables a seamless transition from simulation to real-world testing.

Perception, Communication, and Interaction

The robot is equipped with a humanoid binocular camera, which serves as the foundation for visual perception and computer vision algorithms. A built-in speaker and microphone array enable voice communication that is close to natural, while Wi-Fi 6 and Bluetooth 5.2 connectivity ensure stable data transmission.

A ready-to-use ecosystem for research

The Unitree R1 EDU U3 is designed as a complete solution for laboratories, universities, and R&D; teams; its smart lithium battery with a quick-mount system provides approximately 1 hour of operation, and the included charger allows the robot to be quickly restored to working order. The package is complemented by extensive technical and ecosystem support, which facilitates the implementation of the device even in highly advanced research projects.
