Michigan State University (MSU) has unveiled a newly updated Robofish they have designed and built, which has the ability to glide through water practically indefinitely.

The Robofish has been created by Xiaobo Tan, MSU associate professor of electrical and computer engineering, and uses little to no energy, while its gathers information about the pollution in the water its swimming through.

Robofish is equipped with an array of sensors measure water temperature, quality and other pertinent facts, in the latest update its creators have also renamed it calling the creation Grace, stands for "Gliding Robot ACE.”. Xiaobo Tan explains a little more about his creation:

"Swimming requires constant flapping of the tail,” Tan said, "which means the battery is constantly being discharged and typically wouldn’t last more than a few hours.”- "This is why we integrated both locomotion modes – gliding and swimming – in our robot,” – "Such integration also allows the robot to adapt to different environments, from shallow streams to deep lakes, from calm ponds to rivers, with rapid currents.”
