Magnetically-guided pill sends pictures from inside the stomach Siemens Healthcare and Olympus Medical Systems Corporation are collaborating on the development of a technology for a magnetically guided capsule endoscope (MGCE) system (Image: Siemens) Image Gallery (5 images) Stomach examinations may soon become more comfortable and less invasive with the development of a magnetically guided capsule endoscope. Jointly developed by Olympus and Siemens, the capsule is swallowed by the patient and wirelessly transmits high-res, real-time images from inside the stomach while the doctor navigates using a joystick.

Understanding The RC Quadrocopter The RC quadrocopter, also called the quadcopter, quadricopter, and quad rotor RC helicopter all fall into the category of multi rotor RC which is the latest and fastest growing development in radio controlled vertical lift platforms that are able to take off vertically, hover, and fly in all directions. As the name suggests, there are 4 propellers arranged in a cross type configuration. <A rel="nofollow" HREF=" Widgets</A> There is no single large collective pitch rotor or tail rotor that we are all used to seeing on a conventional RC helicopter.

The illustrated guide to a Ph.D. Imagine a circle that contains all of human knowledge: By the time you finish elementary school, you know a little: By the time you finish high school, you know a bit more: With a bachelor's degree, you gain a specialty: Predator takes visual object tracking to new heights – Computer Chips & Hardware Technology Cameras have slowly made their way into the portable gadgets we all carry around with us and not having a camera in a new device is viewed as a missing feature. It’s got to the point now where the latest smartphones even have two cameras so as to make for better video chat. But while the prevalence and quality of the cameras has gone up, the software still lags behind in terms of being able to identify and track objects in any real-time or captured footage.

Robots learn to walk like a senior citizen - tech - 22 December 2010 Video: Robot moves like a senior citizen Today's humanoid robots are able to run, somersault and even dance – now comes a robot that walks like a senior citizen. It leans on objects in its environment for support to help it move around and complete tasks. Before I Die & Candy Chang What matters most to you Interactive public art project that invites people to share their personal aspirations in public. After losing someone she loved and falling into depression, Chang created this experiment on an abandoned house in her neighborhood to create an anonymous place to help restore perspective and share intimately with her neighbors. The project gained global attention and thanks to passionate people around the world, over 1000 Before I Die walls have now been created in over 70 countries, including Kazakhstan, Iraq, Haiti, China, Ukraine, Portugal, Japan, Denmark, Argentina, and South Africa. The walls are an honest mess of the longing, pain, joy, insecurity, gratitude, fear, and wonder you find in every community, and they reimagine public spaces that nurture honesty, vulnerability, trust and understanding. The Before I Die book is a celebration of these walls and the stories behind them.

Mini robot helicopters build towers, pyramids or walls Sandrine Ceurstemont, video editor If you want to build a small tower or pyramid, flying robots can now do the heavy lifting for you. Daniel Mellinger and his team from the GRASP Lab at the University of Pennsylvania have developed a system that allows flying robots to construct just about any structure (see video above). A human only needs to decide on the design before an algorithm takes over to determine where parts should be placed to create it. Tiny helicopters then follow these instructions and coordinate with each other by choosing the next part placement in a list.

Open a Padlock with One Paperclip, Nothing Else right about now you're probably thinking... "what am I supposed to do with these?".well. Magnetic levitation Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic pressure is used to counteract the effects of the gravitational and any other accelerations. Earnshaw's theorem proves that using only ferromagnetic or paramagnetic materials it is impossible to stably levitate against gravity; however, servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents allow to achieve that. In some cases the lifting force is provided by magnetic levitation, but there is a mechanical support bearing little load that provides stability. This is termed pseudo-levitation. Magnetic levitation is used for maglev trains, magnetic bearings and for product display purposes.

Actroid F Female Telepresence Robot Looks Super Real, Creepy Actroid F can speak in your place, using webcams to watch and mimic your facial expressions and movements. When you speak with your family over a webcam they may be able to see your face, but they don’t have a real body in the room with which they can interact. Why not give them a creepy robot to to talk to instead? Kokoro recently unveiled its Actroid F telepresence robot, a full sized female humanoid with complex facial movements and realistic appearance. Cirque du Soleil performer gets nutty with Padres’ first pitch - Big League Stew - MLB Blog Hideo Nomo and Tim Lincecum(notes) might have two of the most unusual deliveries in baseball history, but they don't have anything on this Cirque du Soleil performer. Watch below as he flips and twists with flair before delivering the first pitch at Monday's game between the San Diego Padres and Kansas City Royals at Petco Park: I'm sure there will be a lot of unimpressed chuckleheads down in the comments that will either pooh-pooh the actual pitch or — heh — claim that he's just a product of Petco Park's spacious environs.

Robot Skin Can Feel Touch, Sense Chemicals, and Soak Up Solar Power When you meet your robot overlord, it may be wearing super-intelligent skin designed by a Stanford researcher--a solar-powered, super-sensitive, chemical-sampling covering that makes your meatbag covering look pathetic. Zhenan Bao is behind the advances, and the recent development centers on a stretchable solar cell system that can expand and shrink along two different axes, making it perfect for incorporation into artificial skin for robots, human prosthetic limbs, or even clothing. Bao's earlier successes with artificial skin have resulted in a highly flexible and durable material, which is part of a flexible organic-chemistry transistor, built on a thin polymer layer.
