This photograph shows the path a Roomba, a floor vacuum robot from iRobot, takes as it cleans your room. It manages to hit every spot although it isn't real efficient on how it does it. The photo was taken by the blogger at Signaltheorist who turned out the lights and used a long-exposure shot over a 30-minute period.
Now here's something interesting, I set up a photo camera in my room, turned out all the lights and took a long-exposure shot of my roomba doing it's thing for about 30 minutes. The result is a picture that shows the path of the roomba through it's cleaning cycle, it looks like a flight map or something. It really hits every spot!
The room looks pretty small. It would be interesting to see Roomba's path in a larger room.
