[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.

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.

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.

Yesterday we looked at the Pac-Man Roomba casemod. In the video, creator [Ron Tajima] expressed interest in seeing Roombas participate in real life games. So we did some digging around and found some used in an interesting augmented reality game. From Brown University, these modified Roomba Create units play various games, like tag, with an underlying goal of developing smarter robots.

The setup consists of a Java powered client/server arrangement. The game server coordinates the Small Universal Robot Vehicles (SmURVs) and builds a database of events for future use. Players can also control the robots through a Java telepresence client.

The units themselves are made up of the iRobot Create with a Mini-ITX computer strapped to the top. They run Linux and communicate over WiFi with the server and players. They also have an IR emitter used in the games to “shoot” other units.

Gameplay has the server acting as the referee and humans only acting as instructors. The humans come into play when the robots are unable to respond based on their existing database of decision making policies. Through the client, players are able to see exactly what the robot sees with the addition of 3D overlays. Future plans for the game include removing the camera view and replacing with nothing but these overlays. One of the final goals of the project was to create a 24/7/365 gaming experience similar to what is found in MMOs and Xbox Live applications today.

[Ron Tajima] fashioned a Pac-Man casemod for his Roomba using 448 LEDs and a SH2 MPU control unit. It features the correct arcade sounds and even the death animation. The bot has Bluetooth access thanks to his previous Wiimote hack. He hopes to use this platform to create a real world version of the game.

[gim] gutted some li-ion laptop batteries to replace his roomba’s battery pack. He had to pick up a li-ion charger and add a protection circuit to deal with the li-ion cells, but ended up with a new lighter pack for his roomba. If you head this way, the protection circuit is a vital component to prevent fires/explisions/etc. Looks like a great resource for robot power or even R/C projects.

(I’m in a robot mood this week, ok?) [Wyatt] sent in his posterbot. Lacking the gift of girly handwriting, he grafted an inkjet printer onto his Roomba to make posters for him. There have been other bots to do this, my favorite being the graffitiwriter. Of course, [Wyatt]’s bot is less likely to get you arrested.

By the way, I’ve got a spare Hack-A-Day shirt sitting here. Send in a link picture of your Hackspace to the tips line. The best/worst will get some attention and the best one gets an official Hack-A-Day shirt.
