UNITREE G1-D U2 Humanoid Robot

The UNITREE G1-D U2 is an advanced humanoid robotics platform designed for precise manipulation, service robotics, and AI development based on real-world observation and interaction. In this configuration, the robot features Dex3-1 three-finger force-controlled hands, increasing the total number of degrees of freedom to 31 and unlocking a whole new level of object handling capabilities. With its mobile wheeled base, humanoid upper body, and adjustable lifting column, the G1-D U2 is a versatile solution for everyday research, testing, and ambitious robotics projects.

Why choose the UNITREE G1-D U2?

• 31 total degrees of freedom for advanced, highly flexible movement

31 Degrees of Freedom for Next-Level Manipulation

Thanks to the Dex3-1 hands, the UNITREE G1-D U2 reaches an impressive 31 DoF, significantly expanding its motion capabilities. Each arm offers 7 DoF, while each hand adds another 7 DoF. The setup is completed by a movable waist with 2 DoF and a lifting column with 1 DoF. This gives the robot the flexibility needed for complex, multi-step tasks, precise object positioning, and operation in demanding environments where repeatability and stability matter.

Dex3-1 Three-Finger Hands for Precision Handling

One of the biggest strengths of the G1-D U2 version is its pair of Dex3-1 force-controlled hands. Each hand features 7 degrees of freedom, including a thumb with 3 DoF and two fingers with 2 DoF each, allowing for accurate gripping and manipulation of complex objects. Fine pressure control makes it possible to handle even delicate and fragile items with confidence. Built-in RGB cameras in each hand also give AI systems a live view of the contact point during grasping.

Adjustable Height and Wide Working Range

The robot is equipped with a lifting column offering 500 mm of travel, enabling operation at heights of up to 2 meters with 1 mm positioning accuracy. A specially designed wheeled base ensures smooth movement and stable operation on flat surfaces. This makes the G1-D U2 especially useful in laboratories, test environments, and service robotics applications where one system needs to adapt to many tasks. The adjustable total height range from 1260 mm to 1680 mm makes it easier to work with different shelves, countertops, and workstations.

Advanced Perception System

The UNITREE G1-D U2 comes with a multi-layer perception system that gives AI algorithms a rich understanding of the environment. A binocular HD head camera with 3840 × 1200 resolution supports scene analysis and spatial orientation, while dual HD wrist cameras with 1920 × 1080 resolution assist with precise manipulation. Additional RGB cameras integrated into the Dex3-1 hands provide close-up visual feedback directly from the grasp area. The system is complemented by a four-microphone array and a 5 W speaker for more natural voice interaction.

High Computing Power for AI and Robotics Development

The G1-D U2 platform is powered by an 8-core high-performance CPU and an NVIDIA Jetson Orin 16G module delivering up to 100 TOPS of computing power. This hardware setup is ready for demanding machine learning workloads and large robotic models, making it a strong choice for developers, researchers, and robotics enthusiasts who want to push their projects further. Support for secondary development and OTA updates also makes long-term software expansion much easier.

Built for Intensive Research and Testing

The G1-D U2 is powered by a 9000 mAh quick-release smart battery that provides up to around 2 hours of runtime, depending on how intensively the arms and hands are used. For longer development sessions or extended experiments, the robot can also operate via wired power. Altogether, it is a stable and reliable platform for manipulation research, service robotics, and human-robot interaction projects.
