Description

Technical Field

[0001] The present invention relates to the technical field of robots, and in particular to an artificial intelligence chess-playing robot. Background Art

[0002] An artificial intelligence chess-playing robot is a robot that combines artificial intelligence technology with mechanical devices and can play chess (such as Go, Gobang, etc.) with humans.

[0003] In the existing patent literature, there is a patent application with publication number CN109421052A and the name of "A Gobang playing robot based on artificial intelligence". This patent application mainly uses a suction cup to pick up and place chess pieces. However, in actual application, the chess pieces are in a mess in the chess piece box, that is, the chess pieces in the chess piece box are in horizontal and vertical states; when the suction cup absorbs the chess pieces in the vertical state, the chess pieces are always in the vertical state. When the suction cup drops the chess piece on the chessboard, the chess piece falls vertically, and the chess piece will be very unstable when it is dropped, which will cause deviations in the placement point, thereby affecting the accuracy of its placement. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an artificial intelligence chess-playing robot, which can install a standardized chess piece limit frame so that all chess pieces can be placed horizontally and evenly. After the chess-playing robot absorbs the horizontally placed chess pieces, it will fall horizontally when placing the pieces, thereby making the chess-playing robot more accurate from picking up the pieces to placing them.

[0005] The technical solution of the present invention is achieved in this way:

[0006] An artificial intelligence chess-playing robot comprises a chess-playing platform, which is divided into a robot chess-playing area and a player chess-playing area; a chessboard is embedded on the chess-playing platform and is located between the robot chess-playing area and the player chess-playing area; a positioning frame 1 is fixed on the chess-playing platform and is located directly above the chessboard, and a camera 1 capable of photographing the whole picture of the chessboard is installed on the positioning frame 1; a chess-playing robot and a chess piece box are fixedly installed in the robot chess-playing area, and only a chess piece box is placed in the player chess-playing area;

[0007] A standardized chess piece limiting frame is placed in the chess piece box in the robot chess game area. The standardized chess piece limiting frame is provided with a plurality of standardized chess holes distributed in a circumferential array. A plurality of horizontally placed chess pieces are stacked and placed in each standardized chess hole. The diameter of the standardized chess hole is the same as the diameter of the chess piece.

[0008] A positioning frame 2 located in the robot game area is also connected to one side of the positioning frame 1, and a camera 2 capable of shooting the full view of the standardized chess piece limit frame is installed on the positioning frame 2.
