Researchers in Japan have developed an odor-detecting drone that uses antennae taken from insects.

The “insect drone” can autonomously find its way to the source of an odor.

The researchers hope that by expanding the range of the drone’s odor detection, and ultimately enabling it to detect the scent of humans, the device can be a useful tool for search and rescue missions at disaster sites.
