Further, referring to fig. 3, 4 and 5, a self-reconstruction mechanism 7 is further provided on the frame 3, and the self-reconstruction mechanism 7 can realize self-reconstruction of the modular spherical robot. The self-reconstruction mechanism 7 includes a second driving mechanism, where the second driving mechanism specifically includes a steering engine 71 installed on the second circuit board 32, the steering engine 71 is a 90-degree micro steering engine, a steering wheel 72 of the steering engine 71 is connected with a mounting frame 73, four first magnetic attraction pieces 74 are uniformly distributed on the circumference of the mounting frame 73, and polarities of the two adjacent first magnetic attraction pieces 74 facing outwards are opposite, for example, the polarities of the four first magnetic attraction pieces 74 facing outwards are N, S, N, S in sequence in a clockwise direction. The steering engine 71 is used for driving the four first magnetic attraction members 74 to rotate 90 degrees clockwise or counterclockwise at the same time. The outward side of the first magnetic attraction element 74 forms a magnetic control area (i.e., a main acting area of magnetic force on the outward side of the first magnetic attraction element 74) in the spherical shell 2. The above-mentioned self-reconstruction mechanism 7 further includes four second magnetic attraction pieces 75 hinged at the top of the skeleton 33, the four second magnetic attraction pieces 75 are located in the four magnetic control areas in a one-to-one correspondence, and the second magnetic attraction pieces 75 can turn around their hinge shafts with the skeleton 33, so that the outward polarity of the second magnetic attraction pieces 75 is changed.
In this embodiment, the outward polarities of the adjacent two first magnetic attraction pieces 74 are opposite, the included angle between the adjacent two first magnetic attraction pieces 74 is 90 degrees, and the steering engine 71 can drive the four first magnetic attraction pieces 74 to synchronously rotate by 90 degrees. For the second magnetic attraction piece 75, at the previous moment, the inner side of the second magnetic attraction piece 75 is attracted to the outer side magnetic force of the corresponding first magnetic attraction piece 74, and at the next moment, after the steering engine 71 drives the first magnetic attraction piece 74 to rotate 90 degrees, the inner side of the second magnetic attraction piece 75 is repelled to the outer side magnetic force of the corresponding first magnetic attraction piece 74, and under the action of the repulsive force, the second magnetic attraction piece 75 can turn around the hinge shaft of the second magnetic attraction piece 75, so that the polarity of the second magnetic attraction piece 75 facing to the outer side is changed. Therefore, through the cooperation of the first magnetic attraction piece 74, the second magnetic attraction piece 75 and the steering engine 71, the outward polarity of the second magnetic attraction piece 75 can be changed, and the region, corresponding to the outer side of the second magnetic attraction piece 75, on the spherical shell 2 can form a magnetic connection point, so that in practice, the outward polarity of the second magnetic attraction piece 75 can be changed to realize the connection and separation of the two spherical robots at the magnetic connection point. Referring to fig. 11, a schematic structural view of two spherical robots in a connected state, and referring to fig. 12, a schematic structural view of a plurality of self-reconstruction forms of a modular spherical robot which can be realized by the present embodiment is shown.
In this embodiment, the number of the first magnetic attraction pieces 74 and the second magnetic attraction pieces 75 is four, in practice, the number of the first magnetic attraction pieces 74 may be designed to be other even number, such as 2, 6, 8, etc., and meanwhile, according to the requirement of the number of the magnetic connection points on the spherical shell 2, the number of the second magnetic attraction pieces 75 may be designed to be any value not exceeding the number of the first magnetic attraction pieces 74. Of course, after the number of the first magnetic attraction pieces 74 is changed, the rule that the polarities of the adjacent two first magnetic attraction pieces 74 facing outwards are different still needs to be satisfied, and when the included angle between the adjacent two first magnetic attraction pieces 74 is α degrees, the angle through which the steering engine 71 rotates once should also be α degrees.
Specifically, referring to fig. 2 and 9, a hinge seat 331 hinged to the second magnetic member 75 is provided on the frame 33, and the hinge seat 331 is specifically two hinge lugs arranged at intervals, and hinge holes are provided on both hinge lugs.

With this structure, the integrity of the second magnetic attraction member 75 can be ensured, and at the same time, the second magnetic attraction member 75 can be ensured to be turned over smoothly.
Further, there is an installation inclination angle between the straight line where the length direction of the first magnetic attraction piece 74 is located and the horizontal plane (in this embodiment, the first magnetic attraction piece 74 is cylindrical, and then there is an installation inclination angle between the axis direction and the horizontal plane), the installation inclination angles of the four first magnetic attraction pieces 74 are staggered according to the first inclination angle and the second inclination angle, the first inclination angle is unequal to the second inclination angle, and the absolute values of the first inclination angle and the second inclination angle are not more than 45 degrees. Specifically, the first inclination angle is a positive value, and the second inclination angle is a negative value; wherein the installation inclination of the first magnetic attraction member 74 is positive when it is inclined from inside to outside, and is negative when it is inclined from inside to outside. The first inclination is positive, and the second inclination is negative, so that for the second magnetic attraction piece 75, the included angle of the central magnetic induction line of the first magnetic attraction piece 74 facing the previous moment and the next moment is larger, so that the torque received by the second magnetic attraction piece 75 is larger, the second magnetic attraction piece 75 can be turned more smoothly, and the outward polarity of the second magnetic attraction piece can be changed conveniently. In this embodiment, the first tilt angle is 1.5 ° and the second tilt angle is-1.5 °.
Further, referring to fig. 6, 7 and 8, the mounting frame 73 is provided with a mounting seat 731 for mounting the first magnetic attraction piece 74, the inner periphery of the mounting seat 731 forms a mounting cavity with an open top, the bottom surfaces of the mounting cavities are obliquely arranged relative to the horizontal plane, and the inclination angles of the bottom surfaces of the mounting cavities of two adjacent mounting seats 731 are staggered according to the first inclination angle and the second inclination angle, so that when the first magnetic attraction piece 74 is fixedly embedded in the mounting seat 731, the mounting inclination angle is just formed between the straight line of the length direction of the first magnetic attraction piece 74 and the horizontal plane, and the mounting process of the first magnetic attraction piece 74 can be simplified.
