Unitree G1 Edu Advanced-U2 is the 29-degree-of-freedom variant in the Unitree G1 Edu series. Compared with the 23-DOF Standard-U1, it upgrades the waist to 3 degrees of freedom and each arm to 7 degrees of freedom. The unit ships with an NVIDIA Jetson Orin NX (16 GB, 100 TOPS) computing module and full secondary development support.
Unitree G1 Edu Advanced-U2 Key Specifications
Total degrees of freedom: 29 (6 per leg, 7 per arm, 3 in the waist). Peak knee joint torque: 120 N·m. Maximum arm payload: about 3 kg. Weight with battery: about 35 kg. Standing dimensions: 1320 x 450 x 200 mm; folded dimensions: 690 x 450 x 300 mm. Battery: 9000 mAh, quick-release, about 2 hours of runtime. Charger: 54V / 5A. Warranty: 18 months.
Computing and Sensing
The Unitree G1 Edu Advanced-U2 pairs an 8-core CPU with the NVIDIA Jetson Orin NX module, adding 100 TOPS of AI computing power for perception and control tasks. Sensing hardware includes a 3D LiDAR and an Intel RealSense D435i depth camera. A 4-microphone array and a 5 W speaker support voice interaction, and Wi-Fi 6 plus Bluetooth 5.2 provide wireless connectivity. Dual encoders on every joint and local air cooling keep the platform stable during continuous operation.
On the Unitree G1 Edu Advanced-U2, joint movement ranges are: waist Z ±155°, X ±45°, Y ±30°; knee 0–165°; hip pitch ±154°, roll −30° to +170°, yaw ±158°. The arm span is about 0.45 m and the calf-plus-thigh length is about 0.6 m.
Compatible Accessories and Related Unitree G1 Models
The Unitree G1 Edu Advanced-U2 uses the same G1 Battery (9000 mAh, quick-release) and G1 Charger (54V/5A) as other G1 models. Related configurations include the Unitree G1 Basic and the Unitree G1 Edu Standard-U1. Full manufacturer specifications are available on the official Unitree G1 page.
