drag2share: Self-healing plastic bleeds when cut, and that's a good thing

Source: http://www.engadget.com/2014/05/11/self-healing-plastics/

Wouldn't it be great if everything was as good at healing itself as our own skin? That's the concept behind a new self-healing plastic that's been developed over at the University of Illinois at Urbana-Champaign. Unlike ordinary plastics, this one contains a thin network of tubes, aping the human vascular system, containing two separate gels that react when they come into contact with each other. When the surface of the plastic is punctured, for instance if shot by a bullet, the two gels pour out, mixing to form a surface roughly 60 percent as strong as the original -- just like a blood clot would on our bodies.

Unfortunately for now, the system only works with holes smaller than eight millimeters, and since it took around three hours to harden, it can't yet be used to save a punctured aircraft while in flight. That said, the team is already working to improve matters, and plans to swap out the gels in favor of foams, which may cover larger areas and harden a lot faster. The Air Force, which funded the research, is hoping that we may eventually see self-healing spacecraft and other heavy equipment where it'd be too dangerous or difficult to send an engineer, like deep-sea drilling. The only downside is that the more vascularized the systems become, the weaker they get overall -- but then that's hardly been a big problem for our bones.

drag2share: This remote-controlled robot can run faster than you (video)

Source: http://www.engadget.com/2014/05/11/outrunner-kickstarter-rc-robot/

RC cars and helicopters are cool and all, but if you want a combo breaker in your collection, here's something different: a multi-legged robot that runs. At the moment, you can only get this remote-controlled sprinter called the OutRunner through Kickstarter, where its creators are trying to raise $150,000 to fund its production. It's available in two different versions that can run on various terrains, including grass, asphalt and dirt. The basic model called the OutRunner Core is a 1.5-foot tall, 3-pound machine that ships with six legs and can move up to 10mph with a battery that lasts up to an hour. Too slow? Well, there's also the OutRunner Performance, a slightly larger version (2-feet tall and 5 pounds) that ships with 12 legs, an HD camera, and can run up to 20mph for up to two hours. Also, the OutRunner Performance can be controlled with an app as well as with its remote control, and can live stream video and sensor data to a smartphone. Unfortunately for those whose expensive toy funds have run dry, neither of these come cheap -- you'd have to pledge at least $249 to get a DIY kit of the basic model.

drag2share: We take flight with Parrot's new Oculus-friendly Bebop drone

Source: http://www.engadget.com/2014/05/11/parrot-bebop/

Parrot still hasn't released that MiniDrone we saw at CES, but its already got something new up it's sleeve: BeBop. Unveiled Monday, the indoor/outdoor quadricopter has a new accessory for extended-range flights, and gives fliers the ability to control its camera using a virtual reality headset. Bebop isn't expected to hit store shelves until later this year, but Parrot let us take one of its few prototypes out last week for a maiden voyage in San Francisco.

The first thing you'll notice is that Bebop looks a little different than other consumer drones. When you're flying in the living room, styrofoam bumpers attach to each side of the aircraft to prevent you from damaging the drone running into walls or ceilings (which, lets face it, we're all prone to do). However, when you're out later at the park the bumpers can come off for unfettered flight. Under the hood, the drone has a combination of sensors (a 3-axis accelerometer, gyroscope and magnetometer if you're interested) that make for an ultra-smooth experience, even in windy conditions. That means if you're trying to fly outside you don't have to worry about a strong breeze accidentally throwing Bebop onto your neighbor's roof. It was one of the most stable drone flights we've ever seen in action, even when it was forced to stand up to San Francisco's winds and an untrained pilot simultaneously.

Regardless of where you're flying, you won't be in the air long. Flight time is just 12 minutes on a full battery charge.Much like Parrot's previous drones, you control that flight using your iOS or Android device and Parrot's controller app, FreeFlight. The application is getting an upgrade to version 3.0, that brings a streamlined experience, but still sports many of the same features you'll find in the older version such as the ability to share videos or program flight paths.

Your iPhone connects to the drone using Wi-Fi, which means you can have up to 300 meters between the two at any given time. If you want to go a little further (and let's be honest, who doesn't?), Parrot has a new accessory called Skycontroller to make your dreams come true. It's essentially a large brightly colored dock for your phone or tablet that gives you physical controls on each side and, more importantly, a giant antenna on top that extends your Wi-Fi range to a whopping 2 kilometers.

The camera is one of the things that make's Parrot's previous drones special, and Bebop is no different. The front of the drone has a 1080p/14-megapixel fisheye lens capable of capturing 180-degree view of the world below. The camera is mounted in a special shock-resistant way that makes video as smooth as possible. 8GB of built-in flash memory stores MP4 and JPG evidence of your high-flying adventure, and controls on your device's screen allow you to turn the camera how you choose.

If you have a virtual reality headset like Oculus Rift laying around, it can be connected to the Skycontroller and pilot the drone's camera as well. We were able to demo it a bit with the prototype, and while it doesn't quite feel like you're flying in the clouds, the experience is pretty interesting. Moving your head around with Oculus controls the drone's camera, but not its movement. Using a VR headset means you'll need to practice up with the Skycontroller beforehand, since you won't be able to see it with something covering your eyes. Overall, it's an awesome trick that's bound to impress your friends if you happen to own both devices, but isn't an experience we could see ourselves wanting very often.

If you're anxious to get your hands on Bebop, you have a little bit of a wait ahead of you. Parrot plans to release the drone in the fourth quarter of this year packaged with and without the Skycontroller. However, the company isn't quite ready to announce an exact date or pricing. A representative told us to expect an MSRP "on par with other consumer drones." Our guess is something roughly in the $300-$400 range.

drag2share: LG admits that one size doesn't fit all with three new G Pad tablets

Source: http://www.engadget.com/2014/05/11/lg-g-pad-7-8-10.1/

LG hasn't quite pulled a Samsung with its new G Pad tablet family, but it's coming close by offering the slate in three different sizes: 7-, 8-, and 10.1-inch. We liked the original 8.3-inch G Pad tablet just fine, but found it was a little too expensive compared to others in the in the 7- to 8-inch size range. Pricing details aren't available yet so we don't know if the company has addressed that angle, but the new tablets will include all of LG's latest software tweaks like Knock Code unlocking, and QPair Bluetooth syncing of notifications with an Android smartphone. Information on availability is also TBA, but the public's first chance to put their greasy palms on these screens will come at the MedPl 2014 trade show this week in Monaco -- we're sure you were already on your way there.

drag2share: G Watch promo video gives us another peek at LG's Android-powered wristwear

Source: http://www.engadget.com/2014/05/11/g-watch-promo-video-lg/

We're not expecting to find out all about LG's "G Watch" smartwatch (and new top of the line G3 phone) until the end of this month, but if you needed another teaser then here it goes. A short promo video for the device doesn't introduce much in the way of details, but if you want to see its Android Wear software in motion or a few 360-degree rotations of its "timeless" metal body, this will suffice. LG is still promising to the "define the smartwatch" with all-day comfort and readiness for anything on a single charge despite an always-on screen, all in a water- and dust-resistant shell.
