The TechJect Robot Dragonfly is a micro UAV designed to mimic an insect; the project started due to a grant from the U.S. Air Force for research into biologically-inspired spy drones. Four models will be available, with the highest model featuring a re-configurable processor, hovering and gilding capabilities, accelerometers, gyroscopes, remote control, GPS, an advanced sensor pack with 18 individual environmental sensors, two cameras, and wi-fi compatibility.
