Parent State ID: 15
Action Taken: change-color(robot1, black, white)
Action Reasoning: The last action taken was moving the robot left to tile_1-0. According to the rules, after a move, the next action should be to change the color of the paint gun. The robot is currently holding black paint, and the next tile to be painted (tile_0-0) is already painted black. Therefore, the robot should change its paint gun color to white to prepare for painting the next tile (tile_0-1) white, as per the goal state pattern.
State Description: Robot1 is now holding white paint while standing on tile_1-0. Tile_1-0 remains occupied by Robot1, and tile_1-1 is clear. The robot is ready to paint the next tile in the sequence.
