preparation example Construction

[0045] The preparation of the soft robot comprises the following steps;

[0046] Step A1, N-isopropylacrylamide referred to as NIPAM, N,N'-methylenebisacrylamide referred to as BIS, and 2-hydroxy-4'-(2-hydroxyloxy)- 2-Methyl propiophenone and DMSO for short are fully mixed together to obtain N-isopropylacrylamide solution for short of NIPAM;

[0047] Step A2, the carbon nanotubes are referred to as CNT, and the CNT is dissolved in PEDOT:PSS solution to configure a CNT suspension; then the ice bath is ultrasonically treated for a preset period of time to obtain a uniform CNT suspension;

[0048] Step A3, mixing the NIPAM solution and the CNT suspension, and ultrasonically treating the water bath for a preset period of time to obtain a NIPAM / CNT mixture;

[0049] Step A4, preparing a jellyfish-shaped mold with a sheet-shaped cavity with light materials;

[0050] Step A5, coating the NIPAM / CNT mixed solution in the sheet-shaped cavity of the jellyfish-shaped mold, and then irra...

Embodiment 1

[0059] (1) Preparation of NIPAM / CNT mixed solution: First, NIPAm (57.5 mg), BIS (0.783 mg), Photo-initiator (1.14 mg), and DMSO (40.6 μL) were thoroughly mixed together to obtain a NIPAM solution. Secondly, CNTs were dissolved in PEDOT:PSS solution to prepare a 5 mg / mL solution, and then sonicated in an ice bath for 10 minutes to obtain a CNT suspension. Finally, the NIPAM solution and the CNT suspension were mixed together at a volume ratio of 3:1, and the water bath was sonicated for 10 minutes to obtain a NIPAM / CNT mixture.

[0060] (2) Preparation of jellyfish-like microsoft robots: a jellyfish-shaped mold was cut out on an acrylic plate with a laser cutting machine, the thickness of the mold was about 200 μm, and the maximum diameter was about 0.7 cm. Apply the NIPAM / CNT mixture obtained in (1) evenly in the mold, and then cover the surface of the mold with a cover glass. Under the sealing effect of the liquid, the cover glass will be completely attached to the acrylic p...

Embodiment 2

[0067] The steps of (1)-(3) in Example 1 were used to prepare jellyfish-like microsoft robots.

[0068] Adjust the pulse signal to control the light source, so that the light source is "on-off" at a higher frequency, so as to achieve the purpose of improving the movement speed of the jellyfish-like microsoft robot. Its principle is as follows: the motion speed of the imitation jellyfish miniature soft robot in the present invention is related to the frequency of its deformation. When the frequency of its deformation increases, the speed at which it bends and drains water increases, so its movement speed also increases. Therefore, when the "on-off" frequency of the light source increases, the movement speed of the jellyfish microsoft machine increases accordingly. In the same way, when the frequency of "on-off" of the light source decreases, its movement speed will also decrease.

Abstract

The present invention proposes a jellyfish-like micro-swimming soft robot driven by visible light and its method. The soft robot includes a deformable soft limb structure; the shape of the soft limb structure can be changed according to the light intensity of the light it bears; When the soft limb structure is placed in the liquid and receives light, the shape change of the soft limb structure of the soft robot can drive the swimming action of the soft robot; the invention can realize the transportation of tiny objects driven by visible light, which makes up for the current microsoft jellyfish imitation. The disadvantages of complex manufacturing methods and the need to improve the feasibility of motion control methods are of great significance to the research of bionic micro soft robots.

Description

technical field [0001] The invention relates to the technical field of bionic robots, in particular to a micro jellyfish-like swimming soft robot driven by visible light and a method thereof. Background technique [0002] Underwater micro soft robot is an important branch of soft robot research. As an aquatic animal, jellyfish can swim freely in the water by periodically opening and closing to push the water body to generate a reaction force. This unique movement mode of jellyfish has attracted the attention of many researchers due to its super high energy utilization rate. [0003] The key to simulating the movement of jellyfish in microsoft robots is how to generate controllable driving forces. At present, the driving methods of jellyfish-like micro soft robots can be divided into three categories: electro-deformation driving, cardiomyocyte driving and magnetic field driving. [0004] Electrodeformation drive is to use high voltage to deform the dielectric elastomer, th...
