Pulito: The LEGO Roomba

When [Dave] installed hardwood flooring in his house, he needed a solution to help automate the monotonous task of routine sweeping. Rather than go out and buy one of the many existing automated sweep robots out there, he decided to use his passion for LEGO Robotics to design and build a NXT based Swifferbot he calls Pulito. His version implements all the important features such as object avoidance using bump sensors, an IR beacon used to automatically return to the charging station, and a photoresistor to monitor the charge of the battery. [Dave] also includes a nifty LEGO sensor multiplexor, allowing him to save on I/O ports, which is almost worth sharing by itself.

Videos after the break.

Roomba dissection videos

Enjoy this 20 minute video dissection of a Roomba 4000. There is lots of great information here, as [Dino] does the dirty work. It is pretty dirty too. Remember, the Roomba is a vacuum. What a pleasant way to waste 20 minutes of your morning. Part 2 is after the break.

All terrain Roomba

This little rover gets around on rough terrain pretty well. [Dean Segovis] built it using parts from a Roomba. The Roomba uses wheels in conjunction with gearboxes that handle a lot of the dirty work in getting this prototype going. [Dean] grabbed four of them, as well as the motor controller board and batter, and installed them on this Rocker-bogie suspension. In the video after the break he mentions that this would be quite a good climber if the batter were relocated to the center of the body. An ultrasonic sensor adds obstacle avoidance with and Arduino taking care of the processing. We can’t wait to see future versions of the Roomba’s rough-and-tumble outdoor cousin.

Google your home with a roomba

Meet GåågleBot. GåågleBot is a modified roomba that will not only vacuum your home, but collect data while it does it. While it is carrying out its normal duties as a floor cleaner, it will take pictures, collecting and analyzing all the data for later searches.  With built in OCR, you can actually search for things using text strings.

Aside from just carrying out its normal job, you can also remote control it via the web. You can even control theirs!

Roombas with UAV Brains Play Pac-Man



[Jack], [Cory], and [Maciej] are playing Pac-Man with Roombas on a lab floor. The Roombas are outfitted with ALIX3d2 single board computers running Gentoo and a software suite developed for UAVs at the University of Colorado at Boulder’s Research and Engineering Center for Unmanned Vehicles. The hardware and software sections are quite in-depth and make for a good read.

Roomba with dustpan style grasper

Remember El-E, the service robot that would retrieve things that you spotted with a laser? The creators of El-E are doing research into other methods of making assistance robots. Their latest contraption is an iRobot Create, basically a  Roomba, with a custom grasping hand. Instead of complex multi DOF assemblies, they have made something that works on the same principle as a dustpan. It has a thin wedge and a sweeping arm that loads items onto it. As you can see in the video, it is quite effective.

Roomba baby cradle

The creator of the pac man modded roomba is at it again. This time, [Ron Tajima] is going in a completely different direction. He has made a baby cradle attachment for his roomba. We don’t know what safety concerns there might be, but the baby seems OK with, so far. We’ve seen robot baby cribs before, but they cost much much more and don’t clean your house.
