Abstract

The invention relates to an inchworm bionic structure based on magnetic drive flexible film drivers and a manufacturing process. The structure comprises a silica gel film at the top layer, a foot structure is arranged below the silica gel film, the magnetic drive flexible film drivers are arranged below the head and abdomen of the silica gel film, the magnetic drive flexible film drivers and the foot structure are bonded with the silica gel film through an adhesive material, and the magnetic poles of the magnetic drive flexible film drivers at the head and the abdomen are opposite. The manufacturing process comprises the following steps of firstly preparing the silica gel film, then preparing the foot structure, then preparing the magnetic drive flexible thin film drivers, and finally preparing the inchworm bionic structure. According to the structure and the method, through the magnetic drive characteristic of the magnetic drive flexible thin film drivers, controllable driving of theinchworm bionic structure under adjustment and control of a magnetic field is achieved; and the manufacturing process of the structure adopts technological means based on photoetching, molding and spin coating, so that accurate and controllable manufacturing of part of structures is achieved, and the organic unification among simple driving conditions, rapid response and large deformation is achieved.

Description

technical field [0001] The invention belongs to the technical field of bionic manufacturing in micro-nano engineering, and in particular relates to a bionic structure and manufacturing process of an inchworm based on a magnetically driven flexible film driver. Background technique [0002] The thoracic and caudal feet of the inchworm can tightly grasp the attachment surface without damaging the attachment surface, and have high adaptability to the material and shape of the attachment surface; Quickly and freely switch between types to provide driving force for crawling; inchworms rely on two pairs of feet and trunks to achieve arbitrary climbing and walking on branches and trunks, with high mobility and good concealment; many advantages make inchworms a Key research objects in the field of bionic soft robotics research. [0003] At present, the mainstream drive methods used in the bionic field of inchworms are electric drive and thermal drive. Among them, the electric driv...
