While some places such as tunnels, some bridges, garages or canyons disallow GPS to function properly, interference or malfunction of GPS satellites could prove disastrous… »

Computer scientists at Karlsruhe Institute of Technology (KIT) developed a technology which enables “airwriting” – a technology which might change the way we input data while on the go while by writing data in air. Since it can be worn like clothes, which can be integrated seamlessly into the everyday life of the user, the… »

Dr. Masaaki Kumagai, director of the Robot Development Engineering Laboratory at Tohoku Gakuin University, in Tagajo City, Japan, and his student Takaya Ochiai have built a robot named BallIP (Ball Inverted Pendulum) that is able to balance on a ball. Such a ball-balancing design is like an inverted pendulum, and thus naturally unstable, but it… »
