Description

[0001] The present invention relates generally to the field of automated board games and intelligent gaming systems. In particular, it relates to a system for an automated chessboard that is integrated into an online simulation platform.

[0002] Chess is one of the most widely played strategic board games, traditionally played on a physical board with manual movement of the pieces and enforcement of the rules by the players themselves. With the advancement of digital technologies, several electronic and smart chessboards have been developed to enhance the game by incorporating sensors, digital displays, online connectivity, and AI-based opponents. However, existing solutions suffer from various technical, economic, and functional limitations. Conventional physical chessboards lack automatic move detection, rule verification, or digital synchronization, making them unsuitable for analytical play, training, or remote interaction.On the other hand, purely software-based chess simulators and online platforms offer robust rule checking and analysis, but do not allow physical interaction with real chess pieces, thus limiting the tactile experience valued by many players. Several electronic chessboards have attempted to bridge this gap by incorporating sensors such as Hall effect sensors, reed switches, pressure sensors, or image-based systems beneath the board. While such systems can detect the presence or movement of pieces, many are unable to reliably identify piece types, enforce the full rules of chess on the board, or ensure accurate real-time synchronization with digital platforms.Furthermore, advanced automated chessboards, which incorporate robotic arms, electromagnets, or CNC mechanisms for the automatic movement of the pieces, are often expensive, mechanically complex, power-intensive, and difficult to maintain, limiting their practical application and commercial scalability. Another significant drawback of existing automated chessboard technologies is the lack of a structured development workflow for validating the chess logic and edge cases prior to hardware manufacturing. In most cases, rule handling, move validation, time mechanisms, and special conditions such as castling, pawn promotion, check, and checkmate are implemented directly on the hardware platform. This approach results in multiple hardware iterations, longer development times, higher costs, and a greater likelihood of discovering logical errors in late development stages.Accordingly, there is a need for an improved automated chessboard system that overcomes the limitations of existing technologies by combining the advantages of physical interaction and digital rule validation, while minimizing hardware complexity and development risk. There is also a need for a system that allows for complete validation of the chess logic through a software-based simulator prior to physical implementation, thus ensuring the consistency, reliability, and cost-effective development of automated chessboard solutions.

[0003] To solve this problem, the present invention offers a system for an automated chessboard that is integrated into an online simulation platform.

[0004] The system enables synchronized physical and digital chess play with precise enforcement of the rules.

[0005] The system is able to capture the position and movement of chess pieces in real time and transfer this data to a digital processing unit.

[0006] The system ensures the uniformity and consistency of the chess rules between the simulator and the physical chessboard through the implementation of a unified logic framework.

[0007] The system allows for easy scalability to support artificial intelligence-based opponents, online multiplayer games, remote monitoring, and the integration of the Internet of Things (IoT).

[0008] The system can be used for mediating embedded systems, game logic, sensor integration, and human-computer interaction.

[0009] The system overcomes the limitations of existing mechanical, image-based, and purely digital chess systems.

[0010] The system can improve the user experience by combining the tactile advantages of a physical chessboard with the analysis and validation functions of a digital chess simulator.

[0011] One embodiment of the present invention comprises providing a system for an automated chessboard integrated into an online simulation platform. The present invention provides an automated chessboard integrated into an online simulator, forming a hybrid hardware-software system for intelligent chess play, rule validation, and system development. The invention introduces a structured two-stage approach, in which a software-based simulator is first developed to fully implement and validate the chess rules and game logic, followed by a sensor-based physical chessboard that reflects the validated logic of the simulator.According to one embodiment of the invention, the system comprises a physical chessboard in which a plurality of sensors are embedded, arranged under individual squares of the board to detect the presence and movement of chess pieces in real time. The sensor data are processed by a microcontroller or processing unit to determine changes in the board's state and transmit corresponding information to a digital system. According to another embodiment, the invention comprises an online simulator implemented using a graphical and logical framework that accurately replicates the behavior of the physical chessboard. The simulator is configured to perform the full enforcement of the chess rules, including move validation, move management, timekeeping, castling, pawn promotion, check, checkmate, and stalemate detection.This simulator acts as a virtual prototype, enabling extensive testing and validation of the game logic before hardware implementation. A unified logic framework ensures synchronization and consistency between the simulator and the physical chessboard, maintaining identical rules and results on both platforms. By validating all game logic in the simulator before deployment to hardware, the invention significantly reduces hardware iteration cycles, development costs, and logical errors. The system is also designed to be modular and scalable, allowing for future integration with artificial intelligence, online multiplayer platforms, remote gameplay, Internet of Things (IoT) services, and educational tools.The invention thus combines the tactile advantages of physical chess with the analysis and validation capabilities of digital systems, offering a reliable, scalable and cost-effective solution for the automated development and use of chessboards.

[0012] In one embodiment, the invention relates to an automated chessboard with an integrated online simulator, designed as a hybrid hardware-software system. The system operates in two coordinated phases: (i) a software-based simulator phase for the complete development and validation of the chess logic, and (ii) a physical hardware phase comprising a sensor-equipped chessboard that mirrors the validated simulator logic. A unified logic framework ensures that the behavior of the physical chessboard is identical to that of the simulator, thereby eliminating discrepancies between virtual testing and real-world operation.In one embodiment, the physical chessboard is a standard 8×8 chessboard with sixty-four squares, each square being equipped with at least one sensor for detecting pieces, such as, but not limited to, Hall-effect sensors, reed switches, infrared sensors, pressure sensors, or equivalent sensor elements. Each chess piece can be configured with a corresponding identifier, such as a magnet or a coded marker, thereby enabling reliable detection of the placement, distance, and movement of the pieces.The sensors generate signals indicating changes in the board's state, which are transmitted to a processing unit, such as a microcontroller or a single-board computer. This processing unit continuously monitors the sensor inputs, identifies valid move events, timestamps the moves, and transmits the detected board state to the digital system via wired or wireless communication interfaces. The hardware module is modular, allowing for variations in sensor type, board material, and processing hardware without affecting the core logic of the invention. The online simulator forms the core logic engine of the invention and is implemented using a graphical and computational framework that enables real-time interaction.In one embodiment, it is developed using a browser-based programming environment, such as JavaScript with a graphics library, although other platforms can also be used. The simulator replicates the physical chessboard layout and implements complete chess rules, including validation of legal moves, move control, castling, en passant, pawn promotion, check detection, checkmate detection, stalemate detection, scoring, and time management. It functions as a virtual prototype, allowing for comprehensive testing of all game scenarios, rule edge cases, and user interactions before hardware production, with any changes or optimizations to the game logic first implemented and verified in the simulator.A key aspect of the invention is the unified logic framework shared by the simulator and the physical chessboard, so that the same rule engine controls move validation and game state transitions in both environments. When a move is made on the physical chessboard, sensor data is processed and assigned to a digital move representation, which is then validated using the same logic employed by the simulator. Conversely, moves generated by the simulator can be displayed on the hardware interface for visualization or for future automated moves, ensuring that the physical and virtual boards remain consistent at all times, eliminating logical inconsistencies, and guaranteeing reliable gameplay.During operation, the system first undergoes a simulator-based validation phase, in which developers and users can test chess logic, timers, special moves, and error conditions without requiring physical hardware. After validation, the logic is transferred to the hardware module, so that during the game, the physical chessboard detects piece movements, transmits changes in the board state, validates moves using the common logic framework, and updates the game state in real time, providing feedback via visual displays, digital displays, or connected interfaces to inform players about valid moves, illegal actions, or game-ending conditions.The system is designed to be expandable and adaptable, and in additional embodiments, it can be integrated with artificial intelligence engines for computer-based opponents, online multiplayer platforms for remote play, IoT connectivity for data logging and analysis, and teaching aids for instruction in programming and embedded systems. The invention is suitable for applications in education, research, entertainment, and commercial gaming environments. By separating logic validation from hardware implementation, the invention offers a scalable, cost-effective, and reliable solution for developing automated chessboards.Thus, the present invention offers a novel and efficient approach to automated chess playing by combining a validated software simulator with a synchronized sensor-based physical chessboard, thereby overcoming the limitations of existing technologies.
