In this case, the protrusion 200 may have elasticity, but the present invention is not limited thereto.

An angle Θ formed between the protrusion 200 and one surface of the body 100 may control a moving direction of the moving device. That is, in the case of the mobile device according to the first embodiment of the present invention shown in FIG. 2, since the angle Θ formed by the protrusion 200 with one surface of the body 100 is an obtuse angle, the mobile device is shown in FIG. However, if the angle Θ is an acute angle, the moving direction of the moving device may be opposite to the direction shown in FIG. The moving method of the mobile device will be described later in more detail.

The elastic part 300 may be formed of a material having elasticity, and may connect the first area 110 and the second area 120 of the body 100. 1 and 2, but the surface-shaped elastic portion 300 is shown, the elastic portion according to the present invention may be a ring-shaped elastic portion 300, such as, for example, a spring. That is, the present invention is not limited to that shown in FIGS. 1 and 2.

The elastic part 300 may relax the body 100 due to its elasticity. For example, when the body 100 is the shape memory alloy described above, the shape memory alloy in a low temperature state may be relaxed by itself by the elasticity of the elastic portion 300.

If fluid (for example, air) is not injected into the fluid injection unit 1320, the fluid (for example, air) that is present in the body 100 may escape and the body 100 may be retracted. In this case, the second region 120 of the body 100 may move in the direction of the arrow, and the first region 110 may stop without moving due to the direction of the protrusion 200 formed in the body.

As such, since the fluid is periodically supplied to the fluid injection unit 1320 and the supply is stopped, the moving device may move in the direction of the arrow shown in FIG. 12.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
