Voice-Controlled Automatic Chessboard for Accessibility

Problem Statement

Many individuals who are blind or have limited mobility are unable to enjoy the strategic and social benefits of playing chess. To address this challenge and align with SDG Goal 10: Reduced Inequalities, the project aims to make chess accessible through hands-free, voice-controlled gameplay.

About Voice-Controlled Automatic Chessboard for Accessibility

Solution

  A fully functional prototype that includes: Oversized Chessboard: Slightly larger than the standard 8×8 layout to prevent piece collision. Embedded Magnets: Neodymium magnets inside each chess piece. Hall Effect Sensors: Placed in each square to detect piece presence. Electromagnets: Under each square to lift and hold pieces during movement. 2-Axis Actuator System: Similar to 3D printer mechanics, used to glide pieces from one square to another. Arduino + CNC Shield: Controls the motors and sensors. Microphone Integration: Captures voice commands to trigger movement. Voice-to-Command Logic: Arduino interprets the spoken move, verifies legality, then executes movement sequence: Activates electromagnet under the piece. Lifts the piece (hovering effect). Moves it to the destination square. Deactivates magnet and resets actuator.  

Additional Info

Idea: Build a voice-controlled automatic chessboard that moves pieces based on spoken commands, allowing players with visual or physical impairments to participate without needing to see or touch the board. Objectives: Design and build a 2-axis movement system using stepper motors. Enable voice input recognition to accept move commands. Accurately move chess pieces using electromagnets and positioning sensors.
