Unitree Dex3-1 Force-Controlled Three-Finger Dexterous Hand

Unitree Dex3-1: The force-controlled three-finger gripper for maximum robotic precision

For developers, researchers, and pioneers in the field of advanced robotics and humanoid AI: The force-controlled, three-fingered Unitree Dex3-1 Dexterous Hand redefines delicate interaction. Designed as the ultimate end-effector upgrade, it brings unprecedented dexterity to complex manipulation tasks with its independently acting fingers. Thanks to high-precision force control, this robotic hand masters sensitive gripping processes as confidently as it does continuous industrial use in laboratory or real-world scenarios.

Highlights of the Unitree Dex3-1 Kinematics

• 7 active degrees of freedom (DoF): The hand features a total of 7 degrees of freedom, divided between the thumb (3 DoF), index finger (2 DoF), and middle finger (2 DoF), for anatomically precise movement sequences.
• Sensitive force control: Through sophisticated, force-controlled feedback, the gripping pressure adjusts dynamically to handle even fragile objects without causing damage.
• Humanoid grip patterns: The clever arrangement of the three fingers allows for both powerful enclosing grips and high-precision pinch and key grips.

Highlights for integration & lightweight design

• Lightweight construction at only 650g: Despite integrated actuators and sensors, the hand weighs just 650 grams, meaning the payload capacity of the supporting robotic arm is hardly affected.
• Seamless R1 compatibility: Perfectly matched as an optional upgrade for the Unitree R1, with the system capable of operating with two of these high-end hands as standard for maximum symmetry.
• Compact form factor: With dimensions of 175 mm × 88 mm × 77 mm, the hand integrates seamlessly with common robotic arms without appearing bulky or restricting workspace geometry.

Technical specifications

Important ordering note: The stated price and technical specifications refer to a single hand. For a full humanoid setup (e.g., on the Unitree R1), two hands are generally required. Please explicitly select between the left and right hand version when ordering.

Advantage for professionals: The Unitree Dex3-1 sets new standards for fine-motor robotic interactions. With 7 active degrees of freedom and highly sophisticated force control, you can eliminate rigid gripping sequences and enable your systems to perform genuine, adaptive learning. Thanks to the extremely low weight of just 650g, professional developers can maximize the net payload of their robotic platforms, while the open ecosystem guarantees precise customization for world-class research.
