Abstract

The invention relates to the technical field of variable-rigidity soft robots, in particular to a variable-rigidity soft module with a bionic glass sponge skeleton structure and a clamp holder, and solves the problem that an existing soft module is poor in rigidity change. The variable-rigidity structure of the module is sleeved on a flexible heating layer, a central limiting layer is arranged inthe flexible heating layer, an elastic main body wraps the side wall and the two ends of the variable-rigidity structure and fills the flexible heating layer, at least one air cavity is formed in theelastic main body located in the flexible heating layer, and the variable-rigidity structure is of a bionic glass sponge skeleton structure. The soft module can be used for designing a soft clamp holder, and the function of grabbing objects of different sizes, different weights and different shapes is achieved by combining the soft body passive deformation capacity and the variable rigidity capacity of the soft module. The design of the variable-rigidity soft module of the bionic glass sponge skeleton is achieved, and the soft module can be further applied to manufacturing of variable-rigiditysoft holders, robot hands, variable-rigidity soft arms and the like.

Description

technical field [0001] The invention relates to the technical field of a variable stiffness soft robot, in particular to a variable stiffness soft robot module and a holder with a skeleton structure imitating a glass sponge. Background technique [0002] In recent years, with the development of new materials and rapid prototyping technology, there has been an upsurge of research on soft robots worldwide. Soft robots involve the disciplines of bionics, robotics, soft materials, and control, and are inspired by imitating molluscs and structures in nature. Soft robots have the advantages of light weight, suppleness, easy deformation, and interactive safety, but low stiffness characteristics affect their load, precise motion, and operational performance, which is a key factor limiting their applications. In order to improve their performance, scholars have studied various variants. Stiffness methods and technologies have also become one of the most popular research directions i...
