Embodiment

[0025] Example: such as figure 1 and figure 2 As shown, a bionic inchworm soft robot includes a head part 1, a soft robot torso part 2, a tail part 3, a bending module 4, a cover plate 5 and a shape memory metal 6, wherein, as Figure 2-Figure 4 As shown, the torso part 2 of the soft robot contains a spiral groove 201, and the radial expansion of the body of the soft robot after being inflated can be prevented by winding fiber wires in the groove. The shape memory metal 6 is installed in the installation groove 203 at the bottom of the robot torso, and then fixed and sealed by the cover plate 5. After the power is turned on, the memory metal bends and deforms, thereby driving the soft robot to bend. The existence of the memory metal changes the rigidity of the soft robot. Furthermore, after the gas is passed into the central airway 205, the torso part 2 of the soft robot will bend and deform when a certain pressure is reached, thereby also realizing the bending deformation ...

Abstract

The invention relates to the technical field of bionics, in particular to an inchworm imitated soft robot. The inchworm imitated soft robot can be driven through combination of a pneumatic manner anda shape memory alloy and comprises a head component, a trunk component and a tail component. The head component and the tail component are arranged at the two ends of the trunk component. The trunk component comprises a trunk body, a head installation module and a tail installation module, and the head installation module and the tail installation module are arranged at the two ends of the trunk body. The trunk body is in a regular long strip shape, the cross section of the trunk body is in a semi-circular shape, and the periphery of the semi-circle of the trunk body is provided with a spiralgroove. The head installation module is connected with the head component, the tail installation module is connected with the tail component, and the rectangular bottom of the trunk body is provided with an installation groove used for installing memory metal.

Description

technical field [0001] The invention relates to the technical field of bionics, in particular to an inchworm-imitating soft robot, which can be jointly driven by pneumatic and shape-memory alloys. Background technique [0002] Inchworm (chǐ huò), the larva of the inchworm. Belonging to arthropods, Insecta, Lepidoptera, insect larvae collectively referred to as Geometridae. The inchworm has a slender body, bends and stretches like an arch bridge when moving, and can straighten obliquely like a branch when resting. [0003] Robots are widely used in many fields such as industry, national defense, and detection. The structural rigidity of traditional robots makes them less adaptable to the environment and unable to adapt to unstructured environments. Bionic soft robots are inspired by nature, have unlimited degrees of freedom, can change shape and size in a wide range, can better adapt to complex environments, and have broad application prospects in industry, military, medic...
