Dex3-1 ForceControlled ThreeFinger Dexterity Hand
Dex3-1 ForceControlled ThreeFinger Dexterity Hand is an official robotic hand developed for the Unitree G1 humanoid robot. Designed without tactile sensors, it provides accurate force-controlled manipulation for robotics research, AI development, and object handling tasks.
Each hand features 7 degrees of freedom, including 3 degrees of freedom for the thumb, 2 for the index finger, and 2 for the middle finger. This configuration enables smooth and precise grasping while maintaining a compact and lightweight design.
Built using Unitree’s self-developed technology, the Dex3-1 offers industrial-grade reliability and stable long-term performance. It is supplied as a single hand, with separate left-hand and right-hand versions available. A standard G1 humanoid robot typically uses two dexterous hands.
This product is available only as an official repair and replacement component and cannot be ordered separately as a standalone upgrade.
