This is an attempt to make a very simple artificial intelligence (AI). To iRobot the concept is simple, get to the laptop. The fun part is that you can make it harder to get to the laptop by adding red barriers to impede iRobot's progress. The AI inside iRobot will get frustrated easily and when it thinks it is stuck it will blow up an area around iRobot and then continue. It can be pretty silly to see how iRobot finally reaches the laptop.
