I love Microsoft Surface. I’ve been in love with it ever since the hands-on demo I got back at CES 2008. Since then, Surface has trickled into a few retail settings (and become the most epic D&D tabletop evar), but it shines when it comes to practical applications, too. Mark Micire at UMass Lowell has taken a Surface table and set it up to control a small swarm of (as yet hypothetical) robots through one of the most simple and effective interfaces I’ve ever seen, a hallmark of Surface. Not only can you just tap, touch, and drag to command as many robots as you like, but if you need to take personal control, the interface for that is extremely slick, Minority Report style. Furthermore, the control interface is also the display, making it fast and intuitive to change commands based on new data. Although it’s not implemented here, a logical next step might be to update the Surface display based on real-time mapping data from the robot swarm.

Another advantage of this kind of system is that you can combine multiple types of robots returning all kinds of data into one seamless command and control display. Like, imagine that some of the swarm consisted of UAVs, and you could add a Z coordinate and send them off to scout ahead. And maybe they have radar or LIDAR, and then that data gets overlaid on the display as well. Sort of like this, except real. Am I gushing? I think I’m gushing. But this is totally cool, and there’s tons of potential. It’s not even that there’s anything that innovative going on here, strictly… It’s just that Surface is able to merge existing hardware and existing controls into a new interface, which makes all the difference.

While I wouldn’t say that interface is necessarily overlooked when it comes to the current generation of robot designs, I do think it’s under-emphasized. People tend to focus on making a totally awesome robot, but unless it’s entirely autonomous, the effectiveness with which the robot operates is dependent on (and in some cases constrained by) the ability of the human user to communicate what they want to the robot quickly and precisely. And even if it IS entirely autonomous, some directions are generally required. I won’t belabor the many examples of this, but I would suggest that a mediocre robot with a good control system is substantially more effective than a good robot with a mediocre control system.

CMU just posted this new vid of their Snakebot (Modsnake) climbing a tree and looking around. It’s still tethered, but it’s a snake, so that just makes it seem more snakey. This isn’t the first video we’ve seen of CMU’s Snakebot climbing stuff, but it’s the first one we’ve seen outside of the lab, so that counts for something, right? Sure!

We already knew that in some specific cases, robots are better pilots than humans, but this footage from Rockwell Collins really drives home the fact that under extreme circumstances, there’s just no out-flying a robot. This small autonomous demonstrator suffers all kinds of damage, but not only does it not crash, it keeps on flying its mission and then lands. For the record, humans are pretty adaptable too, but this next one takes the cake:

Let me just reiterate what’s going on here: the aircraft has no aileron control and is rolling randomly, but is still able to navigate in three dimensional space (it’s flying in a big circle) by using its other control surfaces in conjunction with whatever its roll angle happens to be. At roll speeds of up to 500 degrees per second, there is no way a human could do this, but to the robot, it’s just not that big of a deal.

This technology is great for UAVs, of course, but personally I wouldn’t mind in the least if every airplane I flew on had this capability sitting dormant in a subroutine somewhere until the wing falls off and everybody starts to PANIC and then realizes oh, it’s fine, apparently we don’t need that wing anyway. Next up: cut-rate airlines invest in adaptive intelligent flight control technology, auction off wings and tails.

Getting oil out of water isn’t that hard, on principle. What is hard is getting a huge amount of oil out of an even huger amount of water. If you think about it, this is really a perfect task for a swarm of robots, since it’s simple and repeatable and just needs to be done over and over (and over and over and over) again. With this in mind, MIT’s Senseable City Lab has created Seaswarm, a swarm of networked oil spill cleanup robots:

Seaswarm is designed to be simple, cheap, and efficient. To collect oil, the robots use a wide belt covered in a special hydrophobic nanofabric (about the consistency of a paper towel) that sucks 20 times its own weight in oil (and other pollutants) out of water. The belt moves around like a treadmill, which passes the befouled nanofabric back to be cleaned while simultaneously propelling the robot forward. The video talks about heat being used to separate oil from the nanofiber, while the description on the Seaswarm website makes it seems like the oil is squeezed out using rollers… Whatever floats your robot, I guess.

What I’m not too sure about is where all of that captured oil goes. Using their solar panels for power the bots can collect for several weeks at a time, and the more oil they collect, the heavier they’ll get, and the more energy it’ll take to keep them moving. The website does mention that the oil will be ‘digested,’ which I assume implies microbes, but they’ll either have to collect oil very slowly or have some wicked crazy hungry bugs to be able to get around the problem.

Seaswarm is designed from the water up to utilize swarm behaviors. To combat a spill the size of the recent one in the gulf, about 5000 fully autonomous Seaswarm units would cooperate for a month, using GPS and WiFi to organize themselves for most efficient coverage. And of course, you get all the usual swarm benefits of scalability, adaptability, and robustness.

While Seaswarm as a whole is currently just a concept, they have built an actual working prototype (in the pic above), which was just tested out on the Charles river in Boston, I guess because the designers figured they’d teach the robot some humility when it comes to pollution clean-up.

Vecna Technologies sent along this new video of BEAR, their Battlefield Extraction something Robot. I don’t immediately see any new capabilities, but BEAR does show a penchant for wanton (or premeditated) destruction, smashing through doors and car windows with no apparent sense of remorse. BEAR’s selling point (besides the cute ears) is its ability to lift ludicrous amounts of weight while simultaneously balancing on two extendable treads, which enables it to be (potentially) more useful than a human for performing certain heavy lifting and moving tasks. With all of that power comes a corresponding amount of infrastructure, though, and for BEAR to be really useful in the field it’s going to need to be both durable and easy to repair, and that huge betubed hydraulic backpack looks kinda fragile.
