Tiny underwater robots the size of grapefruits will patrol the ocean like never before. These small robots work in swarms to collect data scientists couldn't gather with previous technology such as monitoring and recording 3-D movements of the oceans internal waves. The women behind the study was author Jules Jaffe. She explains how making a swarm of robots instead of one, it allows the scientists to be in 16 places at once. Just like plankton may get pushed by the internal waves, so does the robots. Today the possibilities are endless for these little robots, scientists believe in the future they could be used during oil spills to track the harmful toxins or get equipped with underwater microphones and act as a giant ear to listen to whales and dolphins.
