     DETAILED DESCRIPTION 
     For a thorough understanding of the present disclosure, numerous specific details are set forth in the following description for purposes of illustration but not of limitation, such as particularities of system structures, ports, techniques, et cetera. However, it should be appreciated by those of skill in the art that, in absence of these specific details, the present disclosure may also be carried out through other implementations. In other instances, a detailed description of well-known devices, circuits, and methods is omitted, so as to avoid unnecessary details from hindering the description of the disclosure. 
     The following embodiments describe toy building block robots and main control boxes for a toy building block robot according to the disclosure. 
     As shown in  FIG. 1  and  FIG. 2 , a toy building block robot of an embodiment of the present disclosure comprises a main control box  10 . The main control box  10  comprises a toy building-block robot main control housing, a toy building-block robot main control board  15 , and a battery  13 . The toy building-block robot main control board  15  is installed in the toy building-block robot main control housing. The battery  13  is connected to the toy building-block robot main control board  15 , so as to supply power to the toy building-block robot main control board  15 . A plurality of connection mechanisms are disposed on the toy building-block robot main control housing, which are used to engage the toy building-block robot main control housing with other components of the toy building block robot. 
     Particularly, the toy building-block robot main control housing comprises a bottom housing  12  and a top housing  11 . An accommodation space is formed between the bottom housing  12  and the top housing  11 , wherein the toy building-block robot main control board  15  is installed within the accommodation space. 
     For the convenience to describe the aspects of the toy building-block robot main control housing, six faces on the toy building-block robot main control housing are respectively defined as a top face  101 , a bottom face  102 , a front face  103 , a back face  104 , a left face  105 , and a right face  106 . 
     As shown in  FIG. 3  and  FIG. 4 , the connection mechanisms of this embodiment comprise a plurality of connecting portions. The connecting portions are disposed on an outer surface of the toy building-block robot main control housing, particularly, the bottom face  102  and the back face  104  of the toy building-block robot main control housing, wherein 6 of the connecting portions are disposed on the bottom face  102 , 3 of the connecting portions are disposed on the back face  104 . 
     It can be understood that, in other embodiments, the location and the amount of the connecting portions on the main control box  10  can be changed in accordance with actual demands. The connecting portions are configured to engage into a butting slot of other components of the toy building block robot, for example, a building block, a servo, or a decoration component of the toy building block robot, thereby realizing the connection between the main control box  10  as well as the building block, the servo, the decoration component, etc. 
     As shown in  FIG. 5  and  FIG. 6 , the connecting portion comprises a connection pillar  1   b   2  and a connection plate  1   b . In this embodiment, the connection pillar  1   b   2  and the connection plate  1   b  are integratedly molded. Each of the connection plate  1   b  is installed on the outer surface of the toy building-block robot main control housing through the connection pillar  1   b   2 . 
     Particularly, there are various methods to fix the connecting portion on the toy building-block robot main control housing. A screw hole  1   b   1  is formed in the connection plate  1   b  and the connection pillar  1   b   2 , such that a screw could pass through the screw hole  1   b   1  to fix the connecting portion on the outer surface of the toy building-block robot main control housing. In other embodiments, the connecting portion and the toy building-block robot main control housing could be integratedly molded, or the connecting portion could be fixed on the toy building-block robot main control housing through adherence. 
     The shape of the connection plate  1   b  could be various. In this embodiment, a square-shaped design is adopted. In comparison with a round shape, a square shape facilitates differentiating different aspects of the connection plate  1   b . In comparison with a rectangular shape or other shapes, since the sides of a square have a same length, the connection plate  1   b  has a same structure in four aspects, and is convenient in connecting with other components of the toy building block robot. 
     A top face of the connection plate  1   b  has direction symbols  1   b   4  disposed thereon. In the assembly process using the connecting portions, if need to assemble in accordance with a particular aspect, the direction symbols  1   b   4  could be used to determine the corresponding aspect. For instance, symbols Δ, □, ⋆, and ∘ can be disposed on the connection plate  1   b , so as to respectively represented four aspects of the connection plate  1   b . In addition, other symbols, graphs, or characters could be adopted to represent the aspects of the connection plate  11 . For instance, the characters E, W, N, and S are used to represent four aspects of the connection plate  1   b.    
     The connection pillar  1   b   2  has at least one set of limit grooves  1   b   3  which is disposed opposite to each other. The limit grooves  1   b   3  are used to match limit protrudes on a butting slot of other components of the toy building block robot, thereby limiting the connecting portion within the butting slot. In this embodiment, four limit grooves  1   b   3  are uniformly distributed on the connection pillar  1   b   2 . Each of the limit grooves  1   b   3  is disposed in alignment with the center of each side of the square connection plate  1   b , and two opposite limit grooves  40  are disposed on a same diameter of the cylindrical connection pillar  1   b   2 . 
     A chamfer  1   b   5  is disposed on a junction between the connection pillar  1   b   2  and the connection plate  1   b . The chamfer  1   b   5  matches a chamfer on the butting slot of other components of the toy building block robot, which facilitates the connection between the connecting portion and other components. 
     Wherein, since the servo has been disclosed in the prior patent application of the applicant, the details are not recited herein. The decoration components are used to decorate the toy building block robot, thereby providing a particular appearance style to the toy building block robot.
