In our recent Nature article, we developed a new theory on how flying drones and insects can estimate gravity direction by combining visual motion sensing with a model of how they move. This discovery forms a parsimonious explanation of multiple phenomena observed in biology and is also an important step for the creation of autonomous tiny drones with even fewer sensors.

Nature Machine Intelligence Paper

Whereas insects seem to control their flight effortlessly with the help of optical flow, robots that attempt to do the same run into problems. We propose as a solution a learning process that allows robots to see distances by means of visual appearance (colors, textures, shapes). Would it be possible that insects do the same?
