Abstract

The application discloses a four-axis chess playing robot system, which contains functional algorithms and device structures, and is mainly suitable for Chinese chess. The functional algorithms are divided into image capturing, image processing, neural network construction, playing against each other operation, system communication and the like, and the device structures are divided into a base platform and matched facilities, a robot body and an interactive touch screen and the like. By using the algorithms and the structures, automatic chess arrangement according to different chess shapes, automatic playing against each other according to different difficulties can be realized, the physical playing against each other requirements of various age groups can be met, and the system also has the function of online playing against each other. In addition, the application adopts a size-adjustable fixed frame, can adapt to most sizes of chessboards on the market, innovatively uses a pneumatic chess piece grabbing mode, cooperates with different calibers and shapes of suction cups, and can adapt to most sizes and materials of chess pieces on the market.
