Attempt Number: 4
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Robot1 is currently holding black while positioned on tile_1-2. Tile_1-2 is already painted black in the goal state, so the next step is to move robot1 to perform a valid action. The adjacent tile, tile_1-3, needs to be painted white, but currently, the robot is holding the black color. The robot should move to tile_1-3 to reposition, allowing an eventual change of color.

New State Description:
Tile tile_0-1 is clear. Tile tile_0-2 is clear. Tile tile_0-3 is clear. Tile tile_1-1 is painted white. Tile tile_1-2 is clear. Tile tile_1-3 is occupied by robot1. Tile tile_2-1 is painted black. Tile tile_2-2 is painted white. Tile tile_2-3 is painted black. Robot1 is on tile_1-3, holding color black. Colors white and black are available for switching.

Action Chosen:
right(robot1, tile_1-2, tile_1-3)
