A new automated vacuum cleaner is programmed to learn the most efficient path to clean a room. It uses its sensors to detect its current location, the position of furniture, and the amount of dirt on the floor. Based on this information, it chooses to move forward, turn left, or turn right. After each cleaning session, it receives a positive signal based on the total area cleaned and a negative signal for each time it bumps into an obstacle. It uses these signals to improve its cleaning path for the next session. In this learning system, what component is the 'agent'?
