Problems solved by technology

[0009] Among these driving forms, the magnetic drive needs to design complex magnetic field and magnetic force changes in advance; the fluid or pneumatic drive type needs to use pumps and compressors to generate compressed fluid, which is poor in portability, and its response time is slow, with medium and high frequency characteristics. Poor; heat-driven methods, mainly using shape memory materials or hydrogel materials, generally have problems of low efficiency and slow response
At the same time, optical drive, chemical drive and other methods also have problems such as poor performance and narrow application range.

Abstract

The invention discloses PVC gel driven flexible mechanical tongs and a preparing method thereof. A multi-layer PVC driver is arranged in a flexible outer frame. A flexible sensor is arranged on the top of the flexible outer frame. The multi-layer PVC driver is formed by stacking a plurality of single-layer PVC drivers, and object grabbing is achieved through the layer number of the single-layer PVC drivers and voltage applying. The PVC gel driven flexible mechanical tongs have the grabbing function and the sensing function at the same time, and on the basis of PVC gel driving, the drive form is simple.

Description

technical field [0001] The invention belongs to the technical field of manipulators, and in particular relates to a flexible manipulator driven by PVC gel and a preparation method thereof. Background technique [0002] According to different driving mechanisms, the main driving types of soft robots are as follows: electric drive, magnetic drive, chemical drive, thermal drive, light drive and air drive. [0003] (1) Magnetic drive: Control the movement and deformation of small structures through complex magnetic field design and magnetic force changes. [0004] (2) Thermal drive: Shape memory alloys, shape memory polymers, or materials driven by thermal expansion are used to manufacture network structures, and temperature changes are generated by heating to regulate the phase state or expansion force of materials to achieve the effect of driving deformation. [0005] (3) Wire drive: control the bending motion of the soft mechanical mechanism through the stretching of the wir...
