A robot that solves and fills alone a sudoku’ grid ! Sudoku are digital puzzles that computers can solve automatically because they obey some simple mathematical rules. The main objective of this project was to build a rudimentary and autonomous robot, like plotting table base on 3D printer idea, which will be able to: analyze the grid of sudoku to be filled; solve the Sudoku problem; fill the grid. That means the robot must be able to process the grid to be solved in order to detect the boxes already filled,their values and then proceed to filling just like the filled grid show bellow. How it works? The hardware of the robot consist at using a Raspberry pi 3 with a camera. A photo of the grid is taken at the beginning of the process.”
