[Jeff] sent in a build of a voice controlled robot he just finished based on the Android ADK and an iRobot Create.

The robot is able to obey voice commands telling it where to go. Currently the robot responds to forward, reverse, left, right, stop, and ‘whistle while you work.’ It’s a creative use of the Android ADK with some obvious applications, but this project really shines with the write up on instructables. It’s rare that we’ve seen a project so well documented; it’s a great project for someone who wants to get their feet wet in the world of robotics.

[Jeff]‘s write up goes through the steps of hooking up the ADK board to iRobot and providing all the electronic necessities. [Jeff] graciously provided the code for his robot if anyone would like to add to his project.

The ultimate goal [Jeff] is currently working towards is something akin to a TurtleBot, while keeping the voice control of the robot. In all, a very nice project.

Meet Bilibot, a modular robot that aims to lower the cost of entry for robotic tinkerers. It combines the Kinect, the iRobot Create, and an Ubuntu box running ROS using some laser cut mounting brackets. These are relatively inexpensive components but the most exciting thing is that there’s already a slew of example out there that use this hardware. For instance, we looked in on ROS body tracking in January that can be directly plucked and used with this hardware. You’ll recognize the base as the iRobot create which was used in video chat robot from last week. The brains of the operation come in a choice of three Linux boxes – two headless and one laptop – which have ROS pre-installed. Watch the open-source autonomy as it tools around the office in the video after the break.

[Johnny Chung Lee], having recently moved from Seattle to Mountain View, wanted a way to keep in touch with his fiancé who would not be relocating for several more months. While most of us would likely consider purchasing a pair of web cams to keep in touch, he decided to do things his own way.  Using an iRobot Create and a netbook, both about $250 apiece, he constructed a remote-controlled video chat robot that he can steer around his former abode from 1,000 miles away. While $500 might seem expensive at first, [Johnny] reminds us that commercial versions likely run into the thousands of dollars.

The whole setup is controlled using custom software to manage the movement of the robot, which can be used in conjunction with freely available videoconferencing applications, such as Skype. He also modified the iRobot’s charging station to charge both the robot and the netbook simultaneously – a process he explains, but precedes with several disclaimers.  Like some of his previous projects we have covered, he has made the C# source used in this project available for download on his site, along with documentation for both the control software and dock modifications.

Check out video of the robot in action after the jump.

The iRobot Warrior 710 is shown here touting a new toy called an APOBS or Anti-Personnel Obstacle  Breaching System.  The system is comprised of an explosive rope pulled by a rocket. We know that sounds pretty awesome, and you can see in the video that it is, in fact, pretty awesome. We don’t condone violence, or war. We do, however, love blowin’ stuff up. This footage was just so pretty, we thought we had to share it. What’s even more amazing is that these guys aren’t battling Apple over the name iRobot.

A morphing robot was demonstrated at the IROS conference this week. This orb has no rigid structure but uses some type of “inflation” system for locomotion. This robot concept is offered up by the iRobot company as part of a DARPA initiative they’re working on. The “inflation” is really a substance in the skin that can be converted from a liquid-like state to a solid-like one. They call this “The Jamming Concept” and give a layman’s explanation in the video we’ve embedded after the break.

When moving, this white ball is a churning, turning, bulging mass of terror. The just-about-to-hatch pods from Alien, or perhaps something from Doom 3 come to mind. The hexapod from IROS that we covered yesterday was amazing, but this really creeps us out. What’s more, this is footage from the iRobot prototypes of a year ago.  The newer stuff can do much more, like having several of these things glob together into one unit.

We’re glad that [DarwinSurvior] sent us the tip on this one, but now we’re not going to be able to sleep at night.

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 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.

[McLurkin] was an entertaining speaker and had an interesting view of robotics. He is optimistic that robot parts will become more modular, so it will be easier to build them, and more importantly, faster to design them.

Some quotes:

• “There’s more sensors in a cockroach’s butt than any robot”
• “12 engineer years to design, 45 minutes to build”
• “If it can break your ankle, it’s a real [rc] car.”

His swarm (pictured above) is made up of over a hundred small identical bots, but he only brought about a dozen with him. The demo was still quite impressive. He had the robots spread out, clump together, play follow the leader and circle the wagons. Each behavior had a very simple rule behind it. To spread out, for example, each robot tries to move away from it’s nearest neighbor. The really fun part was when he had the robots perform a physical bubble sort. The rule for this was that each bot tried to put a higher-id bot on one side and a lower-id bot on the other. After a minute or so of bumping around the bots all lined up in id order.

I was interested in the details of the robot itself. Here’s a picture with the parts labeled.

Each robot has a unique ID number. They communicate with each other via IR and have sensors so that they can tell which direction and how far away the other bots are. The lights on top are just indicators so you can tell what the bots are doing. A mesh network is rebuilt several times a second, creating a directed graph from the ‘leader’ (which can be any arbitrary bot) that connects to each bot in the swarm. Any bot can act as a repeater, relaying instructions to bots that can’t talk to the leader directly.

Robot swarms are not a new idea: they’ve been floating around as concepts for many years. However, [McLurkin] was one of the first to actually build and program a large swarm (at one time he held the record for the largest robot swarm in the world). The idea caught on with researchers and today there’s even an open source robot swarm project. If you’re not up to building a whole bunch of robots, there are also simulators.

After the demo, we asked [McLurkin] about the cost of the robots. He said he didn’t know for sure, but estimated at least $2000 per bot. When we commented that “that’s a lot of money for 100 bots”, he pointed out that compared to the $20K+ that research robots can go for, it’s a bargain. He also said “This whole new world of hobby robotics just didn’t exist in the 90′s”. For robots to be deployed in swarms of hundreds or even thousands, in situations where they can get damaged or lost (search and rescue, military exercises) the cost will need to drop dramatically.

Here he is packing up his robot swarm. After the demo, we half expected them to pack themselves – no, they don’t.
