Problems solved by technology

[0003] Traditional bionic robots are generally composed of rigid modules connected with less degrees of freedom. Although they can meet the needs of precise movement, their rigid structure leads to poor environmental adaptability, and movement in complex environments or narrow spaces will be restricted. In some special occasions not applicable

Abstract

The invention relates to the driving field of soft robots, in particular to a starfish-simulating soft robot driven by a shape memory polymer and a control method. According to the robot, the shape memory polymer is taken as an actuator and a carbon nanotube is buried in a flexible silica gel as a wire to connect the actuator to a control terminal. A flexible silica gel outer sleeve is embedded onto the outer side of the robot, so that the soft robot achieves starfish-simulating movement in water.

Description

technical field [0001] The invention relates to the driving field of soft robots, in particular to a starfish imitation soft robot driven by a shape memory polymer as an actuator and a control method. Background technique [0002] Soft robots are mainly made of soft and elastic polymers, which theoretically have infinite degrees of freedom and the ability to continuously deform, so that soft robots can obtain infinite robot shapes, so that they can reach every point of complex spatial structures . Compared with traditional rigid robots, soft robots can conform to obstacles through their own deformation, and apply soft payloads without causing damage. It will have broad application prospects in many high-tech fields such as medical testing, emergency rescue and disaster relief, and spy investigation. [0003] Traditional bionic robots are generally composed of rigid modules connected with less degrees of freedom. Although they can meet the needs of precise movement, their r...
