Embodiment Construction

[0047] An electrothermally driven soft gripper for bionic gecko toes, including a base and three bionic fingers of the same size;

[0048] The base includes a disc-shaped seat body 101; the front of the disc-shaped seat body 101 is extended with three insertion slots 102, and the three insertion slots 102 are symmetrically distributed around the center line of the disc-shaped seat body 101; A pair of outer threading holes 103 and a pair of inner threading holes 104 are opened between the bottom of the socket 102 and the back of the disc-shaped seat 101;

[0049] Each bionic finger includes a strip-shaped artificial muscle layer 201, a strip-shaped flexible heat transfer layer 202, a strip-shaped variable stiffness layer 203, and a strip-shaped flexible contact layer 204; the back side of the strip-shaped artificial muscle layer 201 is opened along the width direction. There are two V-shaped grooves 205; the inside of the bar-shaped artificial muscle layer 201 is embedded with ...

Abstract

The invention relates to a manipulator, in particular to an electric heating driving-type soft gripper capable of simulating gecko toes and a preparation method thereof. The electric heating driving-type soft gripper solves the problems that when a traditional manipulator grabs the objects with complex shapes, grabbing is not firm, and when soft and fragile objects are grabbed, safe grabbing cannot be achieved easily. The electric heating driving-type soft gripper capable of simulating the gecko toes comprises a base and three bionic fingers with the consistent size. The base comprises a disc-shaped base body. Three inserting grooves are formed in the front face of the disc-shaped base body in an extending mode, and the three inserting grooves are symmetrically distributed around the center line of the disc-shaped base body. A pair of outer side threading holes and a pair of inner side threading holes are formed between the groove bottom of each inserting groove and the back face of the disc-shaped base body in a penetrating mode. Each bionic finger comprises a strip-shaped artificial muscle layer, a strip-shaped flexible heat transfer layer, a strip-shaped variable rigidity layer and a strip-shaped flexible contact layer. The electric heating driving-type soft gripper capable of simulating the gecko toes is suitable for industrial robots.

Description

technical field [0001] The invention relates to a manipulator, in particular to a bionic gecko toe electrothermally driven soft gripper and a preparation method thereof. Background technique [0002] With the advancement of industrialization and the rapid development of the economy, problems such as labor shortage and increased labor costs have attracted more and more attention, and manipulators have emerged as the times require. The manipulator is an important part of industrial robots. It greatly liberates manpower and can replace manpower to complete many complex and tedious labor tasks. It is the backbone of social production. [0003] Traditional manipulators are usually made of rigid materials, and most of them are driven by motors, hydraulic pressure, pneumatics, etc., and have the characteristics of high rigidity, large output load, and high motion precision. However, in practical applications, the traditional manipulator has the following problems due to its own ma...
