Small autonomous underwater vehicles, like the drones of the sea, could be very useful for studying the depths of the ocean and monitoring its changing conditions. But such nautical mini bots can be easily overpowered by turbulent ocean currents. Caltech scientists led by John Dabiri (PhD '05), the Centennial Professor of Aeronautics and Mechanical Engineering, have been taking advantage of the natural ability of jellyfish to traverse and plumb the ocean, outfitting them with electronics and
