In particular, such restrictions are complicated by the work of drones in areas affected by natural disasters, where visibility becomes even worse.

Combining insects to feel odors with advanced robotics, research group. in material.
< p > It is known that animals, including insects, such as butterflies, use their smell to find food, protect against predators and find partners. The males of butterflies can detect pheromones a few kilometers using the “localization of the source of smell”.
< p > inspired by this natural ability, Japanese researchers have developed a drone that simulates such a mechanism.
< p >“Our team continues to develop biogibrid drones that use living insects as elements of smell sensors. In this study we strive to use dynamic movements and mechanisms of living organisms to significantly increase the efficiency of our drones that track smells,” – explained & Terutsuki from the university SHINSH.
< P > The edition reminded that the previous bio -hybrid drone created by scientists had a sensor of electro antennnography, which measures electrical signals from insect antennas. Despite its high sensitivity, the initial model had a limited detection range – only 2 meters. However, researchers have improved this figure.
< p >“To increase accuracy, researchers have introduced a” stepped rotation algorithm, “which mimics how insects make pauses by tracking odors. In contrast In the drone tracking system, which significantly increased its effectiveness, ” – emphasized in the edition.
< P > In addition, scientists have reworked electrodes and speed sensor to meet the structure of the silkwow silkworm antennae, so it was possible to detect the signal more effectively. & Amp; nbsp;

~ < p > “These improvements increased the range of odors to about 5 meters, which makes drone much more effective in real conditions,” – said in the material.
