Embodiment 1

[0032] Example 1 as figure 1 and figure 2 As shown, it includes 2 interconnected motion units, and the motion unit includes a first hydrogel and a second hydrogel; the first hydrogel is a warping section 2 and a second arching section 5, so The second hydrogel is the first arched section 3 and the tail section 6. That is, the first movement unit includes the head section 2 and the first arch section 3, the second movement unit includes the second arch section 5 and the tail section 6, and the first arch section 3 and the second arch section 5 bonding. The warping head section 2, the first arching section 3, the second arching section 5 and the tail section 6 are all magnetically controlled double network cross-linked hydrogels, that is, adding nano-ferric oxide particles and performing the same magnetic Dual-network cross-linked hydrogels programmed for processing.

[0033]The magnetic programming treatment is an operation in which the gelation process of the double netwo...

Abstract

The invention provides a segmented magnetically programmed magnetic control hydrogel software robot comprising at least two interconnected motion units. Each motion unit comprises a first hydrogel anda second hydrogel. One end of the first hydrogel of one motion unit is bonded to the second hydrogel, the other end of the first hydrogel of one motion unit is bonded to the second hydrogel of the other motion unit, the first hydrogels and the second hydrogels are both magnetic control double network crosslinked hydrogels, and the direction of magnetic axes of the first hydrogels is opposite to the direction of magnetic axes of the second hydrogels. By changing the period of a cycle magnetic field, the first hydrogels and the second hydrogels produce different deformations in different directions. By programming the distribution direction of nanometer iron oxide in the hydrogels, differentiated design is carried out on the magnetic control hydrogel software robot, the flexibility of the magnetic control hydrogel software robot is greatly improved, and different action states of different portions of the robot can be effectively controlled.

Description

technical field [0001] The invention relates to the field of soft robots, in particular to a magnetically controlled hydrogel soft robot with segmented magnetic programming. Background technique [0002] As an emerging research topic, soft robots have attracted much attention because they have higher degrees of freedom and greater flexibility than rigid robots. Most soft robots use silica gel, hydrogel, etc. as their main materials. Because of their high toughness and high bending strength, they are far superior to ordinary rigid structure robots in complex working environments. As a kind of soft robot, magnetically driven soft robot is obviously superior to other driving forms of soft robot in terms of wireless control, motion complexity and response speed, and has become a current research hotspot. [0003] In terms of magnetically driven soft robots, the Chinese invention patent discloses a magnetically driven soft crawling robot. In this patent, conductive superelastic ...
