Strong-Arm Revo 2 Basic Edition Hands – natural grip and better interaction

The standout feature of the G1-D U4 version is its five-finger Strong-Arm Revo 2 Basic Edition hands, which deliver a more human-like way of gripping and interacting with the environment. Each hand offers 6 degrees of freedom and 11 joints, enabling smooth finger motion and complex manipulation. With control repeatability of 0.1°, the robot is well suited for tasks that require high precision and stable object handling. The 160 mm hand size makes it easier to use tools and everyday objects designed for people, while integrated RGB cameras provide direct visual feedback for AI systems.

29 degrees of freedom for flexible movement

The UNITREE G1-D U4 features a total of 29 DoF, covering the arms, hands, waist, and lifting column. This configuration provides excellent motion flexibility and supports repeatable, precise manipulation sequences. The 7-DoF arms paired with five-finger hands allow the robot to handle objects more naturally, while the wide waist rotation range of ±155° on the Z axis makes it easier to reach items positioned to the side or at lower levels without moving the entire platform.

Adjustable height and impressive working range

The robot is equipped with a telescopic lifting column with a 500 mm stroke, allowing smooth height adjustment from 1260 mm to 1680 mm with 1 mm precision. This makes it easy to work across different levels, from lower-positioned objects to higher workstations up to 2 meters. It is a great choice for educational labs, robotics classrooms, AI demonstrations, and testing environments.

Up to 100 TOPS of AI computing power

The UNITREE G1-D U4 is a powerful platform for data collection and AI-driven tasks. It is powered by a high-performance 8-core CPU and an NVIDIA Jetson Orin 16G module delivering up to 100 TOPS of computing power. This setup makes it suitable for running advanced artificial intelligence algorithms, visual processing, and robotics applications. OTA update support also helps keep the software ready for future development.

Advanced perception and voice communication

The robot uses a multi-camera vision system that includes a binocular HD camera in the head, HD cameras in the wrists, and RGB cameras integrated into each hand. This setup enables precise spatial orientation, improved object recognition, and better grip tracking. The system is complemented by audio hardware with a 4-microphone array and a 5 W speaker, allowing natural two-way voice interaction.

Reliable power for continuous work

The G1-D U4 is powered by a smart 9000 mAh battery that provides up to around 2 hours of operation on a full charge. The Quick Release battery system makes swaps fast and convenient, helping reduce downtime between tasks. The robot can also operate using a wired power supply, which is especially useful during long demos, testing sessions, or classroom use where uninterrupted operation matters.

A great platform for humanoid robotics learning and demos

The UNITREE G1-D U4 is especially recommended for humanoid robotics education, technology showcases, and dexterity algorithm testing. Its five-finger hands, high motion repeatability, and stable wheeled base make it an exciting platform for hobbyist robotics, research projects, and interactive demonstrations where human-like hand movement and precise control really matter.
