In this June 11, 2015, photo, a hexacopter drone is flown by Intelligent UAS, during a drone demonstration at a farm and winery on potential use for board members of the National Corn Growers in Cordova, Md. The small, relatively inexpensive unmanned aerial vehicles could replace humans in a variety of ways around large farms, transmitting detailed information about crops, directing farmers to problem spots and cutting down on the amount of water and chemicals used.
