Embodiment 1

[0053] Figure 4 It is a circular structure of the present invention, and it is a schematic top view of a negative electrode and a plurality of positive electrodes. like Figure 4 As shown, the shape of the solution carrying structure 1 is circular, and the channels therein are also circular. An electrode 4 is placed in the middle of the solution carrying structure 1 , and the electrode 4 is ensured to be in contact with the liquid metal 2 . There are multiple electrodes 5 surrounding the circular channel, and the rest of the composition is the same as that of the embodiment (1).

[0054] Coordinated control and continuous switching of multiple electrodes 5 can realize local arching of the liquid metal 2 and movement around the circular channel. If multiple electrodes 5 are turned on at the same time, the liquid metal 2 can also realize arching movement in multiple places.

Embodiment 2

[0056] Figure 5 It is a rectangular structure of the present invention, and it is a schematic top view of a negative electrode and a plurality of positive electrodes. The shape of the solution carrying structure 1 is rectangular, and the channels therein are also rectangular. An electrode 4 is placed on the left end of the solution carrying structure 1 , and it is ensured that the electrode 4 is in contact with the liquid metal 2 . There are multiple electrodes 5 arranged along the rectangular channel, and the rest of the composition is the same as that of the embodiment (1).

[0057] Through coordinated control and continuous switching of multiple electrodes 5, local arching of the liquid metal 2 and translational movement along the rectangular channel can be realized.

Embodiment 3

[0059] Image 6 It is a rectangular structure of the present invention, and it is a schematic plan view of the layout of two negative electrodes and multiple positive electrodes. The shape of the solution carrying structure 1 is rectangular, and the channels therein are also rectangular. Electrodes 4 are placed on the left and right ends of the solution carrying structure 1 , and the electrodes 4 are guaranteed to be in contact with the liquid metal 2 . There are multiple electrodes 5 arranged along the rectangular channel, and the rest of the composition is the same as that of Embodiment 1.

[0060] Through the coordinated control and continuous switching of the two electrodes 4 and the plurality of electrodes 5, the liquid metal 2 can be partially arched and moved along the rectangular channel and reciprocated left and right.

Abstract

The invention relates to a software robot. The software robot comprises a bearing structure (1) made of electrical insulating materials, liquid metal (2), a solution (3), at least one first electrode (4) and at least one second electrode (5). A solution tank for storing the liquid metal (2) and the solution (3) and a plurality of pore passages for arranging the first electrodes (4) and the second electrodes (5) are formed in the bearing structure (1). The liquid metal (2) is stored at the bottom of the solution tank, and the solution (3) is stuffed on the liquid metal (2). The first electrodes (4) are connected with a power supply negative pole and immersed into the liquid metal (2), and the second electrodes (5) are connected with a power supply positive pole and immersed into the solution (3) and do not make contact with the liquid metal (2). According to the embodiment of the software robot, the numbers and the positions of the first electrodes and the second electrodes are adjusted, the shapes of the liquid metal are changed through hydrogen generation of the software robot, and thus movement effects with different dimensions are formed. The software robot has the effects of being simple in structure, free from mechanism rotating parts, strong in driving force and stable in performance.

Description

technical field [0001] The invention relates to the field of robots, in particular to a soft robot. Background technique [0002] Soft robot is a new type of flexible robot, which can imitate the movement of insects or soft organisms in nature to drive and control artificial flexible materials. This kind of soft robot can drill into the human body or work in narrow spaces where traditional robots are difficult to enter, so it can be used for post-earthquake rescue or battlefield reconnaissance and other occasions. [0003] Researchers at Harvard University and the Massachusetts Institute of Technology have developed soft robots that rely on air propulsion. However, this kind of soft robot also has certain defects. It needs external devices to realize air supply, suction and control, and it is still difficult to put it into practical use. [0004] At present, researchers have proposed a new soft robot material - room temperature liquid metal. Room temperature liquid metal ...
