The Unitree G1 EDU Ultimate B (U4) is a next-generation humanoid robot engineered for advanced research, intelligent automation, and high-precision manipulation. Featuring an impressive 43 degrees of freedom and dual Dex3-1 force-controlled dexterous hands with integrated tactile sensors, the U4 enables refined, human-like interaction and adaptive control across complex tasks.

At the heart of the U4 lies a powerful AI architecture—100 TOPS of computing powered by NVIDIA Jetson Orin and an 8-core high-performance CPU—delivering real-time processing for AI modeling, sensor fusion, and motor control. With dual encoders at each joint and extra-large movement ranges, the U4 ensures superior mechanical precision and motion fidelity.

Designed for seamless environmental perception and responsive behavior, the robot is equipped with a depth camera, 3D LiDAR, a 4-microphone array, and a 5W speaker. Advanced connectivity with WiFi 6 and Bluetooth 5.2 allows effortless integration into networked systems, research environments, or human-machine interaction setups.

The U4’s 9000mAh quick-release smart battery supports up to 2 hours of continuous operation, while local air cooling enhances system stability under load. With full support for secondary development—including both hardware and software-level customization—and detailed developer documentation, the G1 EDU Ultimate B is a future-proof robotics platform for AI, machine learning, biomechanics research, and STEM education.
