Embodiment Construction

[0024] The present invention will be further elaborated below according to specific embodiments.

[0025] Such as Figure 1-6 The light-driven bionic octopus soft underwater robot, power system and control system are shown. The power system includes a bionic arm and foot, and the bionic arm and foot includes at least three sequentially connected arm and foot units. There are at least three power tubes in the unit. In this embodiment, there are three power tubes in each arm-foot unit, and the position where the three power tubes are implanted in the arm-foot unit is 120° from the line connecting the center of the arm-foot unit section. The number of brachiopod units is four. The power tube is a cylindrical cavity made of photoresponsive material. In this embodiment, the photoresponsive material is liquid crystal gel LCG-70 with photothermal properties.

[0026] The power tube is filled with unsaturated mercury vapor, and the power tube is also provided with a temperature sens...

Abstract

The invention provides a light-driven bionic octopus soft underwater robot which comprises a power system and a control system, the power system comprises a bionic wrist foot, the bionic wrist foot comprises at least three wrist foot units which are connected in sequence, each wrist foot unit comprises a cylindrical silicon elastomer, at least three power tubes are arranged in each wrist foot unit, and the power tube is a cylindrical cavity made of a photoresponse material. According to the light-driven bionic octopus soft underwater robot, bending and deformation in any direction or angle canbe achieved, the flexibility is high, and the operation space is large.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of marine equipment, and more specifically, to a light-driven bionic octopus soft underwater robot. Background technique [0002] Currently, underwater robots can be fabricated using liquid crystal gels (LCG) with photo-thermal properties. Liquid crystal polymers (LCE), liquid crystal elastomers (LCN), etc. are swelled by liquid crystal molecules (LC) to synthesize new photothermal materials LCG that are more sensitive to light stimulation, and convert light energy into heat when exposed to light. As a result, a small change in the temperature of the material is caused, and then the phase transition is excited to cause the material to bend and deform; the LCG is made into strips and placed in water; the bionic sea cucumber is irradiated with ultraviolet light or laser at a specific chopping frequency, which can make it realize the invertebrate Common multiple underwater movement mo...
