[0002] In recent years, with the development of intelligent technology and robotics technology, intelligent chess robots have begun to appear on the market. Chess robots can be used in many scenarios such as family leisure and entertainment, chess competitions, etc. Through physical interaction, they bring users a more immersive chess experience. Intelligent chess robots mainly use machine vision technology to obtain the chess game screen through the camera and monitor the type and position information of the remaining chess pieces on both sides in real time. The AI ​​side controls the robotic arm to move the chess pieces and complete the chess action. Therefore, the key technical technologies of an intelligent chess robot lie in two aspects. On the one hand, it is to quickly and accurately identify the type and position of the chess pieces on the chessboard, and on the other hand, the robotic arm grabs the chess pieces and places them on the accurate target coordinates. At present, common chess grabbing methods include mechanical claw grabbing, suction cup type, electromagnet magnetic suction type, etc. In the process of moving chess pieces, the placement position and direction of the chess pieces often deviate, which is not conducive to the accuracy of image recognition, resulting in the inability to proceed normally. Utility Model Content

[0029] The following will further describe the technical solutions in the embodiments of the present invention in combination with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, a chessboard and chess pieces for a magnetic chess robot are composed of a chessboard 1 and chess pieces 2; the chessboard 1 is a combination, including a chessboard base 11, a small cylindrical strong magnet 12, and a chessboard pattern surface 13; the chess piece 2 is a combination, including a chess piece body 21, a chess piece chassis 22, a chess piece cover 23, a small circular iron sheet 24, a large circular iron sheet 25, and a chess piece pattern surface 26.

[0031] like Figure 2As shown, the chessboard 1 is provided with 90 small cylindrical magnet grooves 111 on the chessboard base 11 according to the center position of the chess pieces on the chessboard pattern surface 13 and the size of the small cylindrical strong magnets 12. After the 90 small cylindrical strong magnets 12 are installed into the small cylindrical magnet grooves 111 of the chessboard base 11, the chessboard pattern surface 13 is attached to the chessboard base 11, and the entire assembly of the chessboard 1 is completed.

[0032] In some embodiments, the chessboard pattern surface 13 is made of a thin velvet cloth material with a chessboard pattern printed thereon, which can increase friction, reduce the sliding of chess pieces, and has higher quality and can better withstand the force of adsorbing chess pieces.

[0033] like Figure 4 As shown, the chess piece body 21 is respectively provided with an upper cover slot 212 and a bottom plate slot 211, which are used to insert the chess piece upper cover 23 and the chess piece bottom plate 22. In some embodiments, the sizes of the two slots can be exactly the same, and the upper and lower positions do not need to be identified during assembly.

[0034] like Figure 5 and Figure 6 As shown, the chess piece chassis 22 is provided with a small circular iron sheet groove 221 according to the size of the small circular iron sheet 24 ; the chess piece upper cover 23 is provided with a large circular iron sheet groove 231 according to the size of the large circular iron sheet 25 .

[0035] like Figure 7 As shown, the chess piece pattern surface 26 is printed with chess general characters, and a direction mark 261 is marked directly below the characters. In this embodiment, the mark uses a triangular mark, which can be replaced with the company's LOGO, or other patterns or colors can be used to assist machine vision technology in identifying the direction of the chess piece.

[0036] like Figure 3 The figure shows the assembly process of the chess piece 2. First, the small circular iron sheet 24 is placed into the small circular iron sheet groove 221 of the chess piece chassis 22, and then the chess piece chassis 22 is inserted into the chassis groove 211 of the chess piece body 21 to complete the installation of the chess piece chassis. Similarly, after the large circular iron sheet 25 is placed into the large circular iron sheet groove 231 of the chess piece upper cover 23, the chess piece upper cover 23 is inserted into the upper cover groove 212 of the chess piece body 21 to complete the installation of the chess piece upper cover. Finally, the chess piece pattern surface 26 is affixed thereon to complete the entire assembly of the chess piece 2.

[0037] More specifically, the small circular iron sheet 24 in the chess piece 2 is the same size as the small cylindrical strong magnet 12 in the chessboard 1. When the mechanical arm moves the chess piece to a certain point, a small deviation occurs. The small cylindrical strong magnet corrects the position of the chess piece through magnetic attraction. The large circular iron sheet 25 in the chess piece 2 is to allow a larger area for adsorption with the electromagnet of the mechanical arm. A stronger suction force can make it easier for the chess piece to leave the chessboard. Because there is only an iron sheet inside the chess piece 2 and no magnet is installed, the chess pieces 2 will not be attracted or repelled by each other due to the influence of magnetic force.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Obviously, many modifications and changes can be made according to the content of this specification. Any technician in the technical field to which the utility model belongs can make any modifications and changes in the form and details of implementation without departing from the spirit and scope disclosed by the utility model, but the scope of patent protection of the utility model shall still be based on the scope defined by the attached claims.
