Typically, we send rovers to our planetary neighbors one at a time — but what if we sent a small team of smaller, less impressive robots instead? That’s the idea NASA is exploring at Kennedy Space Center with Swarmies: a quartet of four autonomous robots designed to work together to complete a single mission. Working as a colony of insects might, the four machines use a combination of WiFi, GPS and webcams to survey an area, assess its value and contact the other robots if assistance is needed. The robots are less advanced than a typical rover might by, but working in tandem allows them to cover more ground. It also serves as a security measure: if one rover fails , there are three left to complete the mission. “For a while, people were interested in putting as much smarts and capacity as they could on their one robot, ” says Kurt Leucht, one of the engineers working on the project. “Now people are realizing you can have much smaller, much simpler robots that can work together and achieve a task” Right now the machines are just prototypes, but if all goes well they may one day be used in search and rescues missions, or even scaled up for use in space. “Assuming this pays off, ” Leucht says, ” we know somebody’s going to take this and extend it and go beyond the four or five rovers we have here.” [Image credit: NASA/Dmitri Gerondidakis] Filed under: Robots , Internet Comments Source: NASA

DigitalGlobe’s WorldView-3 satellite has only been in space for less than half a month, but it’s already proven itself capable of shooting high-res images just like the company promised. Just a few days after Lockheed Martin flew it to orbit, the satellite quickly went to work, snapping pictures of Madrid, Spain. As you can see in the gallery below, it’s pretty easy to spot vehicles, rooftops and landmarks in these images. DigitalGobe says its services can benefit companies and governments that want to assess vehicles and monitor a region’s development (housing, infrastructure and road networks), among other things. Conservationists can also use it to monitor natural resources. While these first set of images are already great, the company will start delivering even clearer, closer satellite snapshot to all its customers by February next year. Comments Source: DigitalGlobe

Yes, cloud services like Dropbox make it easy to share folders through public directories and links, but you still have to put those folders in the cloud in the first place. Wouldn’t you rather share them straight from your PC? BitTorrent hopes to make things that direct with its big Sync 1.4 update . Now, you can share folders with others just by giving them web links; you don’t have to wait for the files to reach a remote server, or rely on Sync’s slightly more obtuse Key system. You don’t have to sign up for an account, either, and you can still limit access to prevent others from messing with precious documents. About the only headache is that your recipient needs Sync, although BitTorrent promises that it will walk first-timers through the process. The 1.4 release is also an excuse for BitTorrent to give Sync a much-needed interface makeover. While a lot of the basic concepts remain intact, the new front end is both prettier and easier to understand on Macs and Windows PCs — arguably very important when people are more likely to be trying Sync for the first time. You can grab the desktop upgrade (which includes Linux) right now, and matching updates for both Android and iOS should be ready later today.
