Embodiment 1

[0063] As shown in the figure, the frog tongue-like soft actuator of this embodiment includes an inflatable tube, a support tube, a flexible film tube body, a metal wire, an end fixing member, and an adhesive member for grasping objects. In this embodiment, the flexible film tube body is made of polypropylene film, and the flexible film tube body is provided with a set of connecting edges along its axial direction, and the connecting edges are parallel to each other; based on this structure, when the flexible film tube body is not inflated, it is strip.

[0064] Typically, the wire of the present application is in a crimped shape. In the present application, the metal wire is arranged on the inner wall of the flexible film tube body, and the flexible film tube body is driven to move by the metal wire. Based on the crimp-like structure of wire, it can crimp the flexible film tube under normal circumstances, as shown in the figure. In this example, the inflation tube can be a ...

Embodiment 2

[0092] In order to expand the application of the actuator, on the basis of the previous actuator, the following are designed and produced Figure 12 Shown is a frog-like jumping soft robot. The frog-like jumping software robot of this embodiment includes a jumping support component and a robot body. There are two jumping support components. The jumping support components are respectively arranged on the robot body and can drive the robot body to move. The jumping support assembly of this embodiment includes an inflatable tube for connecting with an air source, a support tube, a flexible film tube body, and a metal wire. In this embodiment, the flexible film tube body is made of polypropylene film, and the flexible film tube body is provided with a set of connecting edges along its axial direction, and the connecting edges are parallel to each other; based on this structure, when the flexible film tube body is not inflated, it is strip.

Abstract

The invention discloses a frog tongue-like soft actuator and its application, aiming at solving the common problems of complicated control process, difficult structure design and high cost in existing soft robots. It includes an inflatable tube, a support tube, a flexible film tube body, and a metal wire. The flexible film tube body is made of a film, and a connecting edge is arranged on the flexible film tube body. This application imitates the action of frog predation, utilizes the characteristics of stretching and curling of metal wire, and controls the change of pressure to realize the corresponding movement of the actuator. Furthermore, based on the structural design of the sticky object, the actuator of the present application can realize the action of sticking and picking up the object. On this basis, the inventor further utilizes the actuator to realize novel bionic frog jumping and water swimming movement modes. The soft actuator of the present application has the advantages of simple control, low manufacturing cost, high expansion and contraction efficiency, etc., and provides a new approach for the development of future soft robots.

Description

technical field [0001] The invention relates to the field of soft robots, in particular to a soft actuator, in particular to a frog tongue-like soft actuator and its application. Through the research on frog movement, the inventor proposes a new soft actuator, and a bionic frog jumping mechanism and bionic frog swimming mechanism based on the soft actuator, which have the advantages of simple structure, easy control and low cost, and are expected to be applied. In the corresponding field, and promote the development of soft robots. Background technique [0002] In recent years, researchers have used soft materials to make soft robots by imitating mollusks in nature. This kind of robot can realize motion modes such as creeping, twisting, crawling, swimming, etc., can change its shape and size arbitrarily in a wide range, and can greatly stretch and shrink in various large environments. Based on the advantages of soft robots, it has become a research hotspot. [0003] Abroa...
