Embodiment 1

[0063] As shown in the figure, the software actuator imitating a frog tongue in this embodiment includes an inflatable tube, a support tube, a flexible film tube body, a metal wire, an end fixing piece, and an adhesive piece for grabbing 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 sides along its axial direction, and the connecting sides are parallel to each other; based on this structure, when the flexible film tube body is not inflated, it is strips.

[0064] Typically, the wire for this application is in a coiled form. 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 crimped structure of metal wire, it can usually crimp the flexible film tube, as shown in the figure. In this example, the inflation tube can be a rubber tube, a...

Embodiment 2

[0092] In order to expand the application of the actuator, on the basis of the previous actuator, the following design was made Figure 12 A soft robot that imitates a frog jumping is shown. The frog-like jumping soft robot of this embodiment includes a jumping support assembly and a robot body. There are two jumping support assemblies. The jumping support assemblies are respectively arranged on the robot body and can drive the robot body to move. The jump 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 sides along its axial direction, and the connecting sides are parallel to each other; based on this structure, when the flexible film tube body is not inflated, it is strips.

[0093] In this embodiment, the metal wire i...

Abstract

The invention discloses a soft actuator simulating a frog tongue and an application of the soft actuator, and aims to solve the problems that existing soft robots are generally complex in control flow, difficult in structural design and high in cost. The soft actuator comprises an inflation pipe, a supporting pipe, a flexible film pipe body and a metal wire; the flexible film pipe body is preparedfrom a film; and a connecting edge is arranged on the flexible film pipe body. The soft actuator simulates the predation action of a frog, by the aid of the stretching and curling characteristics ofthe metal wire, through control on the change of pressure, corresponding motions of the actuator are realized. Furthermore, on the basis of the structural design of a sticky object, the actuator can realize the action of sticking objects. On the basis, the actuator is further used for realizing the novel motion manners of bionic frog jumping and swimming in water. The soft actuator has the advantages of simplicity in control, low manufacturing cost, high telescopic efficiency and the like, and a new way is provided for development of future soft robots.

Description

technical field [0001] The invention relates to the field of soft robots, in particular to a soft actuator, specifically a frog tongue-like soft actuator and its application. The inventor proposes a new soft actuator based on the research on frog movement, and the bionic frog jumping mechanism and bionic frog swimming mechanism based on the soft actuator. It has the advantages of simple structure, easy control, and low cost, and is 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 molluscs in nature. This type of robot can realize movement modes such as creeping, twisting, crawling, swimming, etc., can change its shape and size arbitrarily in a wide range, and can be stretched and contracted in a variety of different environments. Based on the advantages of soft robots, it has become a research hotspot. [0003] ...
