Roomba, Economics and Long-Exposure Photography
by Signaltheorist on Apr.20, 2009, under Uncategorized
Earlier this weekend I picked up a Roomba, as my old vacuum cleaner bit the dust(ha!) after an altercation with a shoelace. Like any good geek, I immediately went online to see what kind of modifications I could make to this little beast. What I ended up finding out was that iRobot, the company that makes the Roomba, actually promotes and encourages hacking the devices, even offering the tools to do so. This made me wonder about the business sense behind it, and, in my eyes, it’s quite good. This is all I’ve been able to think of so far, please add if you think of anything else.
Pros:
- -Consumers end up designing functional modifications, which can be used in later versions of the device
- -Hacking voids your warranty, thereby reducing warranty claims
- -Revenue from sales of hacking tools/interfaces
- -Active community promotes the product
Cons:
- -Brand diluted by other items under Roomba name
- -Brand may get an image of being complicated
I’m sure I’m missing some obvious ones here, please comment. Now here’s something interesting:
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!

I’m such a yuppie. It hurts me.

Long Exposure Roomba Photos are Pretty, Insightful. | Robotics Blog
May 23rd, 2009 on 1:41 am[...] If you haven’t heard of a Roomba before, it is a small, $100-$600, robotic vacuum cleaner that roams around and picks up after its messy human counterparts. Some creative Roomba owners have gotten the bright idea to take some long exposure photographs of their Roomba doing its thing. The result is a beautiful image offering insight into how the Roomba bot navigates around the room. The Roomba tirelessly cleans every nook of the bedroom“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.

Long exposure shows Roomba cleaning path | Sameer Halai
October 18th, 2011 on 12:05 pm[...] Long exposure shows Roomba cleaning path Posted on May 9, 2009 by Sameer If you have been following my tweets, I am a big Roomba fan. I have been quite fascinated by the way the Roomba seems to get every part of the room, detects corners to spend more time and energy there etc. The user manual that comes with it tries to explain that the seemingly random motion is actually a concerted exercise in discovering, maximizing power use and efficiency. However, it’s easiest to understand if you look at the long-exposure shot taken by signaltheorist. [...]

After all, what good is an autonomous device if it misses half the dirt, right? Here’s another long-exposure photo of a Roomba’s cleaning path over a 30-minute span. It’s rather impressive how a Roomba really does cover the whole area. (Here are the details behind this Roomba experiment.) [...]

Awesome Shot!! What camera, apature, ISO did you use?
May 9th, 2009 on 5:34 pm
I’ve had the Roomba 560 for about a year or so I guess?
It still works well. I don’t know about hacking it, there are some projects on the web and I’ve built a BT serial dongle but really, what are you going to do with it? Play some tunes, send some custom commands, grab some stats, that is about it. The thing cleans floors. It does it better than I would care to. I chuck it in a room when I leave for work, the scheduler starts it up at 11:00, I get back from work, empty the bin when needed, and then put it in the living room and press the dock button.
In my next house I will probably get a little roomba elevator, and THEN I will use the hacking to make my house AI send the roomba to the appropriate room at the right time
Also, remember, if you have bought a recent model you are looking at a fifth-generation (or so) product. That is a lot of engineering time and customer feedback, right there.
Anyhow, there are some roomba hacks on youtube and the other usual suspects, but so far I haven’t seen anything that actually adds something useful to the Roomba. It does what it does, and it does it fairly well.
The pathfinding algorithms are fun, nice shot!
May 9th, 2009 on 6:57 pm
Ok. Now someone write a hack for the Roomba so you can use long exposure photography and get the Roomba to draw cartoons, the Mona Lisa, secret messages. Why? Why not?
