Computer Science doctoral candidate Zhongli Liu demonstrates "Hawk," an unmanned mini helicopter-based aerial wireless kit for search, rescue and surveillance that she helped to design with her team Yinjie Chen, Benyuan Liu, and Asst. Prof. Xinwen Fu at the UMass Lowell Center for Cyber Forensics to assist in thwarting cyber crime. Hawk can intercept all of the wireless traffic to detect a signal sent during a hack; it flies in a perpendicular flight line and can be remotely programmed to search in a grid using this pattern. As Hawk approaches the pre-specified destination, it will stop at the precise signal strength detected. Liu and her team won the silver medal at the 2011 ACM Student Research Competition (SRC) in Las Vegas for their design of Hawk. See also: http://www.uml.edu/research
More about this demonstration: Only the landing is manually controlled by the hand-held controller. The software controller steers HAWK for autonomous takeoff and fly, searching for a mobile phone, which is flagged for being easy to spot. The picture-in-picture at the low left corner is taken by the on-board Nokia n900. The other picture-in-picture is the flight route displayed in our control program. At the end, you will see that we successfully localized the smartphone and "caught the flag." You can also enjoy our human assisted landing technique for windy weather.
