Compact Robotic Hand for Precision Manipulation and Research
Product Overview
The DexRobot DexHand021S 3-Fingered Dexterous Hand is a compact and lightweight robotic end effector designed for precise manipulation, adaptive grasping, and research-oriented robotic applications. Featuring a three-finger anthropomorphic layout, DexHand021S offers a balance between dexterity, control simplicity, and mechanical robustness.
Compared with multi-finger dexterous hands, the 3-finger configuration reduces system complexity while maintaining the ability to perform power grips, pinch grips, and precision handling. This makes the DexHand021S ideal for robotics research, humanoid platforms, service robots, and intelligent manipulation systems where flexibility and ease of integration are critical.

How It Works
The DexHand021S uses three independently controlled fingers to grasp and manipulate objects of various shapes. Each finger can adjust its position and grip force to conform to the object surface, providing stable and adaptive grasping.
The control system coordinates finger motion for precision handling while allowing simplified programming compared to multi-finger hands. When integrated with a robotic arm or humanoid platform, the dexterous hand enables tasks such as object pickup, tool handling, and fine manipulation.
