For example, mosquitos are known to move really well. Scientists are trying to create an insect-sized drone with this kind of agility that can be used in life-and-death situations, like finding a person trapped inside a collapsed building.
Kevin Chen, an assistant professor at the Massachusetts Institute of Technology (MIT) and lead author of the study, said that he had spent a lot of time looking at the flapping-wing physics that could be applied to drones. That is how he and his team were able to invent a new insect-sized drone. The weight of this robot and the physical size looks pretty much like a dragonfly, he says.
