Robot Fish Swims Long Distances for Underwater Research


A group of University of Michigan researchers have developed a robotic fish that, according to them, can swim practically indefinitely, gathering data on lakes and riverbeds.

The robot is called Grace, an acronym for Gliding Robot ACE and it's equipped with sensors to gather data and measure water's temperature and quality. Grace is able to autonomously swim both by flapping its tail as well as gliding through the water. This combination lets it travel long distances.
