Scientists at the University of Sheffield have created a computer model of how bees avoid hitting walls – which could lead to a breakthrough in the development of autonomous robots.
Researchers from the Department of Computer Science built their computer model to look at how bees use vision to detect the movement of the world around them and avoid crashes.
Bees control their flight using the speed of motion – or optic flow – of the visual world around them, but it is not known how they do this. The only neural circuits so far found in the insect brain can tell the direction of motion, not the speed.
This study suggests how motion-direction detecting circuits could be wired together to also detect motion-speed, which is crucial for controlling bees’ flight.
“Honeybees are excellent navigators and explorers, using vision extensively in these tasks, despite having a brain of only one million neurons,” says Dr Alex Cope, lead researcher on the paper. [Read more…] about Computer model of how bees view the world could be a breakthrough for robotics
