Abstract

The invention discloses a magnetic response bionic crawling soft robot and a preparation method thereof, and the bionic crawling soft robot comprises a magnetic elastic body and a magnetic response driver; the magnetic elastic body is in a grid shape, the grid comprises a transverse elastic body and a longitudinal elastic body, magnetic particles are arranged in the longitudinal elastic body, and the magnetic particles are magnetized in a first magnetic field so that the magnetic elastic body can be shaped into a curve state; the magnetic response driver is used for applying a second magnetic field to the magnetoelastic body so that the elastic body can be changed from the horizontal state to the curve state. By means of the technical scheme, the problems that a soft robot is difficult to manufacture, and complex magnetic fields in different directions and different sizes need to be applied during crawling are solved, and popularization of the soft robot is facilitated.

Description

technical field [0001] The present application relates to the technical field of bionic robots, in particular to a magnetic response bionic crawling soft robot and a method for preparing a magnetic response bionic crawling soft robot. Background technique [0002] Most of the existing crawling robots are traditional rigid robots, which are generally composed of a power system, a transmission system and an actuator, and have the characteristics of fast movement speed and high output power, but this rigid robot has poor flexibility and environmental adaptability. On the contrary, due to the low elastic modulus of the materials used, soft robots can withstand large deformation, have the advantages of simple structure and strong adaptive ability, and have attracted more and more researchers' attention and developed rapidly. [0003] Soft robots are mainly made of active soft materials with stimuli-responsive properties, which can imitate the complex movement patterns of animals ...
