Unitree Dex5-1 Tactile Hand for Unitree H1/H1-2 (Left)

Description

• Unitree Dex5-1 Tactile Hand (Left)
• Designed for Unitree H1/H1-2 humanoid robots
• 20 Degrees of Freedom with Independent Finger Replacement
• 94 Tactile Sensors per Hand Supports advanced tactile feedback
• High-Speed Reflexes with Micro Force-Controlled Joints
• Ultra-Precise Fingertip Control with 1mm repeat positioning accuracy

TheUnitree Dex5-1 Tactile Hand for Unitree H1/H1-2 (Left) is a next-generation robotic hand engineered for high-performance humanoid applications, designed specifically for compatibility with the Unitree H1 and H1-2 robots. Featuring 20 degrees of freedom and individually replaceable fingers, the Dex5-1 sets a new benchmark in robotic dexterity. Each joint is designed for smooth backdrivability, eliminating the rigid, “stiff-hand” sensation and providing the fluid responsiveness required for reinforcement learning (RL) environments. Its four-finger lateral swing (22) enhances grip reliability, adapting intelligently to curved and irregular surfaces.

Built for both speed and sensitivity, the Dex5-1 integrates 94 tactile sensors per hand and supports secondary algorithm development, giving researchers and developers complete control down to the millimeter. High-power density hollow-cup motors, micro force-controlled transmission, and ultra-low damping joint design ensure lightning-fast reflexes and seamless motion. With fingertip positioning accuracy of 1mm, gripping strength of up to 10N, and a load capacity of up to 4.5 kg, the hand offers both power and finesse.

From its ultra-small joint gap design that prevents snagging, to its 1000Hz communication rate and real-time perceptual feedbackincluding position, torque, stiffness, and IMU datathe Dex5-1 is engineered for high-fidelity interaction. Whether in academic research, advanced robotics training, or real-world manipulation tasks, the Unitree Dex5-1 delivers unmatched tactile control and adaptability.
