Which group Unitree Dex3-1 belongs to and how it is built
A subcategory encompassing robotic hands with multiple degrees of freedom, designed to perform complex grasping, regrasping, manipulation, and object interaction tasks. Unlike simple grippers, dexterous hands enable more advanced finger coordination and a broader variety of grasp types.
Force-controlled dexterous robotic hand components are advanced manipulator end-effectors equipped with force, torque, or contact sensing, designed for safe and precise object handling. They are used in humanoid robots, research platforms, and tasks requiring delicate or adaptive grasping.
A class of robotic hands with three working fingers. Designs of this type represent a compromise between mechanical complexity, manipulation capability, and ease of control. They are used in lightweight manipulation systems, research platforms, and select humanoid applications.
