Description

Technical Field

[0001] The invention belongs to the technical field of robots, and in particular relates to a robot based on a pseudo three-dimensional Hilbert curve. Background Art

[0002] Currently, when the fluid resistance is large or the fluid resistance changes greatly in the working environment, the movement of the robot often requires a lot of energy to offset these resistances, and a precise control system is required to reduce the impact of the fluid resistance changes and move to the specified position, which will increase costs.

[0003] Therefore, it is necessary to design a robot that is less affected by the environmental fluid resistance. Summary of the invention

[0004] The object of the present invention is to provide a robot which is less affected by the resistance of the environmental fluid and can move.

[0005] To this end, the present invention provides a robot based on a pseudo-Hilbert curve, comprising a robot body and a controller. The robot body is composed of sixty-three telescopic units connected end to end according to a second-order pseudo-three-dimensional Hilbert curve. The telescopic units include a telescopic rod, a first telescopic rod bracket, a second telescopic rod bracket, a cube connecting block and a driver. The first rod end of the telescopic rod is fixedly connected to the cube connecting block through the first telescopic rod bracket, and the second rod end of the telescopic rod is fixedly connected to the second telescopic rod bracket. The cube connecting block is a hollow structure, and the driver is placed in the inner cavity of the cube connecting block, wherein the second bracket of the telescopic unit is used to be fixedly connected to the three-dimensional connecting block of another telescopic unit, the telescopic rod is connected to the driver through a wire, and the controller controls the extension and retraction of each telescopic rod by controlling the driver.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The present invention combines the pseudo three-dimensional Hilbert curve in mathematics with a robot. It is composed of sixty-three telescopic units connected to each other, which can realize the movement of the robot body. At the same time, because the space formed by the robot is a non-closed space, it has multiple uses. For example, when the fluid in the environment contacts the robot, it will pass through the internal space of the robot. Therefore, the robot is less affected by the resistance of the environmental fluid during operation. In addition, the non-closed space inside the robot can be used to carry objects, so some operations and transportation of objects can be carried out.
