Hungry Fruit Flies are Extreme Ultramarathon Fliers

04-22-21

Michael Dickinson, Esther M. and Abe M. Zarem Professor of Bioengineering and Aeronautics; Executive Officer for Biology and Biological Engineering, has discovered that fruit flies can fly up to 15 kilometers (about 9 miles) in a single journey—6 million times their body length, or the equivalent of over 10,000 kilometers for the average human. "The dispersal capability of these little fruit flies has been vastly underestimated. They can travel as far or farther than most migratory birds in a single flight. These flies are the standard laboratory model organism, but they are almost never studied outside of the laboratory and so we had little idea what their flight capabilities were," Dickinson says.

Machine Learning Helps Robot Swarms Coordinate

07-14-20

Soon-Jo Chung, Bren Professor of Aerospace, Yisong Yue, Professor of Computing and Mathematical Sciences, postdoctoral scholar Wolfgang Hönig, and graduate students Benjamin Rivière and Guanya Shi, have designed a new data-driven method to control the movement of multiple robots through cluttered, unmapped spaces, so they do not run into one another. "Our work shows some promising results to overcome the safety, robustness, and scalability issues of conventional black-box artificial intelligence (AI) approaches for swarm motion planning with GLAS and close-proximity control for multiple drones using Neural-Swarm," says Chung.
