There are two models in this app, Robot and Cell. The table contains 25 cells.
Each cell has x-coordinate and y-coordinate.
The left-bottom cell is (0, 0).
Each cell also has references to its surrounding cells: north, east, south and west.
When a robot is on a cell, a reference will be created to link the robot to the cell (cell.robot).
A robot has a direction, when robot is moving, turning left or right, we use direction to determine the next cell the robot will be on.
You can use a SQLite client https://sqlitebrowser.org/ to see how the data is stored.
