The robot dexterous hand is a robot end effector that is highly imitative of the human hand. It adopts a five-finger anthropomorphic structure design and simulates the joint movement of the human hand through more than 15 degrees of freedom to achieve fine operations such as grasping and pinching. It is the core component of the robot to perform complex tasks. It belongs to the gripper type device in the robot end effector. Different from the traditional two-finger gripper, it has multi-modal perception and intelligent control capabilities, can adapt to irregular objects and complete precision operation tasks.
