CyPhy Works reveals tethered flying bots that can spy on you indefinitely
 

A new venture from an iRobot co-founder called CyPhy Works has borne fruit in the form of two flying drones dedicated to surveillance duty. The first, called Ease, is a mere foot in diameter by 16-inches tall and can fly safely in tight spaces or through open windows or doors, thanks to its petite size and ducted rotors. It packs a pair of HD cameras along with a thermal imager and can stay aloft permanently, in theory, thanks to a microfilament tether attached to a ground station -- which also makes it impervious to weather, tracking and interception at the same time, according to CyPhy. The second drone, an insect-like quadrotor called Parc, is designed for higher flying missions thanks to its larger size and maximum 1,000-foot altitude. It also uses a tether and can stay aloft for 12-hours on a single ground-station battery, letting it spy from afar with on-board HD, night-vision and thermal cameras. The company's yet to take any orders, but thanks to investors and government grants, the snoopy little bots could be getting up into your business one day soon -- as creepily shown in the video after the break.
