Abstract

The present invention provides a soft artificial muscle driver applied in deep sea, comprising shape memory alloy wire (SMA), fluid filler, flexible tube, ceramic sheet, sealant, wire and metal tube, and the shape memory alloy wire is arranged on the In the flexible tube, the fluid filler is arranged in the flexible tube, the flexible tube is set between two ceramic sheets with holes, the metal tube is fixed at both ends of the shape memory alloy wire, the ceramic sheet, The flexible pipe and the metal pipe are connected by sealant, and the wires are led out from both ends of the shape memory alloy wire. The invention utilizes the characteristic of the shape memory alloy material to drive deformation through temperature change phase transition, and realizes a deep-sea pressure-resistant shape memory alloy wire (SMA) linear driver.

Description

technical field [0001] The invention relates to the technical field of robot drivers, in particular to a soft artificial muscle driver. Background technique [0002] The traditional underwater deep-sea robot structure is usually assembled by motors, pistons, joints, hinges and other components, with sufficient power, high power and mature performance. However, there are also many disadvantages, such as bulkiness, low safety factor, poor environmental adaptability, low reliability, low transmission efficiency, and large noise. In the deep sea environment, the extreme water pressure and temperature environment have brought great challenges to underwater robots, and brought great burdens to traditional hard watertight shell systems, motors and transmission mechanisms. [0003] The thick and hard pressure-resistant shell greatly increases the technical complexity, structural size and overall quality of the underwater robot. The soft body, excellent flexibility and strong envir...
