Why We Need Them
Robotics can´t yet mimic insects´ flying abilities, so scientists are developing controllable cyborg butterflies that could fly sample-collection missions through buildings.
How They Work
A chip, implanted during the pupal stage, could control locomotion, monitor the air, and override instincts to feed, mate, and avoid certain environments.
Darpa has solicited public proposals but hasn´t announced a winner. Scientists are in the early stages of research; a final product is years away.
Implanting a chip in a developing insect could stunt its growth and damage its ability to fly as an adult.
