I don't own one, but in the video, it looks like it went over its own tracks a bit...I'm guessing low...and stealing the original thoughts of HKou...42%.

Re: Episode 8 Contest: The Winner!

The contest is now officially OVER :o Thanks to everyone that participated, I've seen some great probabilistic thinking as well as lots of guesswork, but as always there can only be one right answer. Here are some after shots of the arena after the Roomba had its way with it, take a final guess:

After two and a half minutes, the Roomba managed to pick up.....

38% of the colourful dust!

Our winner is scotty.a.simpson, with a guess of 42%. A special shout out to HKou, who was thinking along the right lines...I like your optimism, give robotics another few years and your floors will get cleaned in no time.

It's sooooooooo bad! :?
Is somebody working on fractal space filling curves to increase the efficiency?
Using a relative odometry system (for example an insect like optical flow) coupled with a Sierpinsky like curve can provide a granual approach to clean the floor.

- Track overlap: 30% -> 50%
- Dust-pickup-efficiency: 80% -> 50%

==> 37.2%!

So close! :)

can you please explain what method you used to calculate it?
I'm very curious! :geek:

Roomba vacuum cleaner batteries

Postby Spacious on 13 Jul 2009, 18:34

The Roomba (at least the Roomba 400) is a nice piece of work, IMHO.

The battery does die out pretty quickly at times, and I've gotten a new one (specifically vac-400nmh-33) at this place: www.batterytex.com.

Thought that might be helpful for enthused Roomba users! Oh well...they haven't yet made a robot (to my knowledge) that can replace/recharge its own batteries...

Those guys at http://www.batterytex.com are pretty good. I think at least for the roomba 400 and the like. The Vac-400nmh-33 it was. They got it to me pretty quickly, nice and freshh.

Very nice experiment Adam. I would have guessed lower than that around 20% based on the time limitation.

Did you leave the experiment running until the roomba had finished its cycle? if you did what was the % at that point ?? Did you see a difference between the black tiles and the white?

Compared to other posters I'm no expert on the logic, But i believe it is based on random coverage rather than most efficient.

Because it is based on random it is designed to take a long time to clean. the theory being everyone is out of the house so who cares if it takes 2 hours to hoover.
This also has the extra bonus of it going over the same spots more than once.
