Problems solved by technology

[0003] At this stage, the multi-joint dexterous hand uses some connecting rod structures or other mechanisms to form fingers in series. In order to have great flexibility, it is necessary to add a separate motor to each joint of the finger and perform separate control, so that the manipulator The control is extremely complicated, and due to the use of a large number of control devices, the manufacturing cost is also greatly increased

Abstract

The invention discloses a transformable three-finger dexterous hand. The transformable three-finger dexterous hand comprises a deformation mechanism, underactuation fingers and a controller, the underactuation fingers are fixedly connected with the deformation mechanism, the controller is electrically connected with the deformation mechanism and the underactuation fingers, a plurality of gear setsare arranged in the deformation mechanism and drive the underactuation fingers to move, the underactuation fingers are provided with double parallelogram mechanisms for connecting finger tips with finger bases. The deformation mechanism composed of the multiple gear sets, the underactuation fingers connected through the double parallelogram mechanisms and the controller, the three-finger dexterous hand having multiple degrees of freedom, being simple to control and transformable, and being suitable for multiple grabbing pieces is formed.

Description

technical field [0001] The invention belongs to the technical field of robots, in particular to a deformable three-finger dexterous hand. Background technique [0002] Robotic dexterous hand is an important part of robot involvement and operation, and an important way to realize local fine operation of robots. Due to the urgent needs of engineering applications and the development of robotics technology, dexterous hand has developed into a special research field. Compared with simple end manipulators, the dexterous hand has strong versatility, rich perception capabilities, and can achieve precise and stable grasping that meets geometric closure and force closure. [0003] At this stage, the multi-joint dexterous hand uses some connecting rod structures or other mechanisms to form fingers in series. In order to have great flexibility, it is necessary to add a separate motor to each joint of the finger and perform separate control, so that the manipulator The control is extre...
