I mini drones, that is, drones that have the shape of an insect are very particular robotic devices, as they manage to enter places inaccessible to human beings, photographing what that they see and therefore offering a real-time report of the situation. This is a sector in which science is investing a lot, and which is therefore becoming increasingly sophisticated.
But as insect drones can see in condition low light? To create an interesting and useful model, researchers at the Swiss Federal Polytechnic studiedbreathed to insects, the real ones, who possess a very special visual apparatus. Insects don't see very well in terms of resolution, but they compensate for this imbalance by being very sensitive to light and moving bodies.
The Swiss researchers then created a vision artificial robotics which does not have infinite resolution, but which is sensitive to movements and also to light, to allow these robotic jewels not to 'rattle' in dark conditions but can still make the most of the present light conditions, even the most minimal.
THEsynthetic eye it is 2 millimeters large cubes and barely weighs 2 milligrams It is a device created with a lens connected to three photosensors arranged in a triangular configuration which record electromagnetic radiation during flight. In this way the flying robot is controlled by software that calculates distances and allows it to move easily even in very extreme light conditions. Although this is a very important scientific discovery, the researchers' aim is to equip insect drones with a multiple eye system, that it can in the future allow you to obtain a complete view of the place and facilitate landing and monitoring of the most special areas of our planet.
