Self-driven three-order megaminx and control method

Abstract

The invention provides a self-driven three-order megaminx and a control method, and relates to the technical field of educational toys, the self-driven three-order megaminx comprises a control module,a power supply module, a wireless communication module and steering engines which are arranged in the megaminx, and each driving block corresponds to one steering engine and is connected with a rotating shaft of the steering engine; a coded disc is arranged on the driving block, the current angle of the coded disc is read through a groove-shaped correlation photoelectric sensor, and then the rotating angle of the driving block is determined and sent to the control module in real time. The control module is used for recording the rotating track of each driving block in real time, controlling the steering engine to drive the driving block to rotate along the reverse direction of the rotating track of each driving block, and further driving the magic surfaces where the driving blocks are located to rotate to realize reverse order recovery; through cooperation of the groove-shaped photoelectric correlation sensor and the photoelectric coded disc, self-driven restoration can be rapidly achieved without auxiliary cooperation of an external megaminx solving robot, the cost is greatly reduced, and the user experience is improved.

Description

technical field [0001] The present disclosure relates to the technical field of educational toys, in particular to a self-driven three-order five Rubik's Cube and a control method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Five Rubik's Cube is also called Dodecahedron Rubik's Cube, each face of which is pentagonal. The mathematical arrangement algorithm of Five Rubik's Cube is very complicated. If you don't know the arrangement rules, it will never be a product that can be recovered by just turning a few times for beginners. , so many people think that playing Rubik's Cube is a difficult thing. [0004] The inventors of the present disclosure have found that in the prior art, the Rubik's Cube solving robot is mostly used to restore the Rubik's Cube, which has the following problems: (1) Most of the existing Rubik's Cube solving ro...

Problems solved by technology

[0004] The inventors of the present disclosure have found that in the prior art, the Rubik's Cube solving robot is mostly used to restore the Rubik's Cube, which has the following problems: (1) Most of the existing Rubik's Cube solving robots arrange a manipulator around the Rubik's Cube to control the rotation of the cube surface, When it is necessary to rotate the upper and lower cube faces, it is often necessary to rotate the upper and lower cube faces through a flip mechanism, and the form of the manipulator is often a very precise six-axis manipulator to clamp each cube face of the Rubik's cube to rotate the Rubik's cube, but using these structure, the connection structure between the Rubik's Cube and the manipulator is unstable, not only is it not easy to clamp the Rubik's Cube, but also greatly increases the cost of the manipulator; (2) The structure of this kind of manipulator is fixed and does not have a fault-tolerant structure. When the Rubik's Cube is stuck , the Rubik's Cube is easy to explode under the extrusion of the manipulator, which affects the effective restoration of the Rubik's Cube; (3) In addition to the flipping mechanism, in order to enable the Rubik's Cube to enter the interior of the Rubik's Cube solving robot for restoration, there is also a lifting mechanism for transporting the Rubik's Cube. The overall size of the Rubik’s Cube robot is large, it takes up a lot of space, and the cost is high; (4) For the special-shaped Rubik’s Cube such as the third-order and fifth-order Rubik’s Cube, the robot needs to design a separate control algorithm and manipulator for solving the Rubik’s Cube. Simply using a six-axis manipulator cannot Realize the effective fixation of the rotating five Rubik's Cube
