Robot fish glides out of Michigan State University, tells you if the water is clean

Autonomous fish might make great leaders, but it turns out that robot flippers are a huge drain on battery life. Not a problem for Xiaobo Tan -- he and a group of Michigan State University scientists have built a robotic fish that glides through the water.
