The initial state consists of a 3×3 grid of tiles labeled from tile_0-1 to tile_2-3. There is one robot, robot1, which starts on tile_0-1 and is holding the color white. The available colors for the robot to use are white and black. The tiles that are clear (unpainted and not occupied) are tile_0-2, tile_0-3, tile_1-1, tile_1-2, tile_1-3, tile_2-1, tile_2-2, and tile_2-3. The robot can move vertically and horizontally between adjacent tiles, provided the destination tile is clear. The adjacency relationships are defined such that each tile has specific tiles directly above, below, left, and right of it, allowing for movement within the grid.
