Drone learns to see like an insect
A team from TU Delft and the Westfälische Hochschule presents an optical flow-based learning process that allows robots to estimate distance on the basis of the visual properties (shape, colour, texture) of objects.
‘Optical flow’ means that insects perceive the speed at which objects move through their field of vision. The drone researchers have adapted this strategy to their flying robots – and their flight strategy looks surprisingly natural.
This artificial intelligence-based learning strategy improves the navigation skills of small flying drones and offers a new hypothesis on insect intelligence. The article appears today on the cover of Nature Machine Intelligence. (JW)
