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

Action Reasoning:
The next action should be to paint-down the tile directly below the robot (tile_2-1 is already painted), so move right to tile_1-2. This prepares us to paint tile_1-2 with black as required by the goal state.

New State Description:
- Robot1 is now on tile_1-2, holding the color black.- Tile_0-4 is clear.- Tile_1-1 is clear.- Tile_1-2 is occupied by robot1 holding color black.- Tile_1-3 is clear.- Tile_1-4 is clear.- Tile_1-5 is clear.- Tile_2-1 is painted black and is no longer clear.- Tile_2-2 is painted white and is no longer clear.- Tile_2-3 is painted black and is no longer clear.- Tile_2-4 is painted white and is no longer clear.- Tile_2-5 is painted black and is no longer clear.- Color white is available for switching.- Color black is available for switching.

Action Chosen:
right(robot1, tile_1-1, tile_1-2)
