Unitree Dex3-1 Force-controlled, dexterous three-finger hand (tactile version)

Unitree Dex3-1 (Tactile Version): The tactile three-finger robotic hand for advanced AI sensing

The evolution of robotic manipulation reaches the next level: The Unitree Dex3-1 (Tactile Version) expands upon the proven, force-controlled three-finger hand with high-resolution tactile feedback. Developed for top researchers in the fields of machine learning, reinforcement learning, and humanoid AI interaction, this end-effector simulates the human sense of touch more realistically than ever before. Through the synchronous interplay of active force control and multidirectional sensing, the hand masters even highly complex, slip-prone, or fragile objects with complete autonomy and precision.

Highlights of the Unitree Dex3-1 tactile sensing

• 33 integrated tactile sensors: High-resolution sensor arrays on the fingertips and contact surfaces detect even the slightest changes in pressure, surface textures, and sliding movements in real time.
• Closed-loop control: Enables direct sensory feedback to the control system to dynamically adjust the gripping pressure to the object millisecond by millisecond.
• Advanced AI training data: The tactile version provides valuable physical interaction data that is essential for training advanced AI models and neural networks.

Highlights for kinematics & construction

• 7 active degrees of freedom (DoF): Divided into 3 DoF for the thumb, 2 DoF for the index finger, and 2 DoF for the middle finger – the optimal configuration for natural-looking biological hand movements.
• Feather-light weight of 650g: Despite the impressive density of sensors and internal wiring, the weight remains minimal, ensuring the full dynamics of the supporting robotic arm are maintained.
• Plug-and-play for humanoid platforms: Perfectly dimensioned (175 mm × 88 mm × 77 mm) and prepared for seamless integration with the Unitree R1 humanoid robot, both mechanically and via software.

Technical specifications

Ordering and configuration note: The stated price and all technical specifications refer to a single hand. Two units are required for a complete humanoid dual-arm setup (e.g., on the Unitree R1). Please explicitly specify the configuration as either a left or right hand in your shopping cart.

Advantage for professionals: The Unitree Dex3-1 Tactile closes the gap between pure force control and genuine physical perception. Thanks to the 33 integrated tactile sensors, you can train demanding AI models with real haptic data to prepare robots for unforeseen everyday and industrial interactions. With its extremely light profile of only 650 g and native system compatibility, you minimize your integration effort and secure a forward-looking hardware foundation for groundbreaking research and development results.
