The Nighthawk Micro Air Vehicle (MAV) is a rugged, fully automated unmanned aerial vehicle (UAV) made of carbon fiber composite. It uses GPS and autopilot technologies for navigating unfriendly territories to conduct intelligence, surveillance, and reconnaissance missions. Its range is over 10 km (6 miles) and flight time is more than 60 minutes. The Nighthawk weighs 1.6 lb (725 gm), has a wingspan of 26 inches (66 cm), and a cruise speed of 18 to 30-plus knots. The MAV is equipped with 8-channel command and control, 4-channel video, and operates on batteries. It has forward and side-looking electro-optical cameras and a side or forward-looking thermal imager. A PC-based user interface provides real-time visual feedback and point-and-click waypoint navigation. The system can also be operated in semi-manual and manual flight modes. MAVs are stored fully assembled and ready to launch in a tube measuring 6 inches (15.2 cm) in diameter and attached to an assault pack. The assault pack's outer pockets hold a rugged laptop computer, the ground control station, and an antenna assembly. The pack's total weight is about 15 lb (6 kg).

Ann, you might want to include underwater robots in you future blogs, they are used extensively for mine countermeasures, waterborn IED defeat, search and rescue, ship hull maintenance and many other critical tasks. Some good examples might be the SeaBotix LBV: http://www.seabotix.com/products/vlbv950.htm or the LBC, which can both swim and attach to and crawl on subsea structures: http://seabotix.com/products/lbc.htm Both have numerous commercial uses in addition to maritime security.
Thanks, Think Deep, we've already done two slideshows on nautical robots, some of which are military, and many of which are AUVs, UUVs and/or ROVs: http://www.designnews.com/author.asp?section_id=1386&doc_id=246206 http://www.designnews.com/author.asp?section_id=1386&doc_id=262528 SeaBotix is a new one to me, though--thanks for the link.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
