Harvard researchers have built an artificial fly that flies like real fly. One day it could provide discreet surveillance of suspects, detect hazardous materials and disrupt battlefield communications.
The artificial fly is about the size of a horsefly, according to a report in Technology Review. The mainly carbon-fibre device weighs 60 grams and has a 3cm wingspan. For now it flies on a tether that also supplies power.
Researchers in Harvard's Microrobotics Lab, led by Robert Wood, plan to give the fly more autonomy with a portable power pack and untethered flight.
The US Defense Advanced Research Projects Agency, which funded the original internet, is paying to develop robofly.
