    I like how it traces a perfect mathematical nautilus figure before hitting something and switching over to its psuedo-random bouncing and wall following behaviors. For a device that really doesn't know where it is in space, it does a great job of ensuring good coverage of an unknown area.

      That's a roomba going into it's extended clean mode, when the 'I found dirt!' system fires. It's goes into a circle and deeper clean mode.

        Nah, the spiral is one of its starting routines. Basically, when it starts, it randomly chooses one of ? algorithms. One of them is to assume a start in the middle and spiral outwards, simultaneously gaining some idea of the room's size, and cleaning a big swath in the middle.

        The dirt detect makes one small, tight circle, and fires a bright blue LED.

        Err.. ok, said observations are based on the Discovery w/ original firmware. I don't know what they're like now, other than having better escape systems.

    I saw this and wondered, "how did he get the battle map from BSG projected on his bedroom floor?"

    I am going to have to try that, once I fix my Roomba's circle dancing problem.

    I'm just impressed with the appropriate choice of music.

  8. That's what my cat does, too. Only it uses all the furniture surfaces, too, and does not suck.
