Researchers from the National University of
Singapore (NUS) Department of Mechanical Engineering have unveiled a new
underwater robot they have built in the form of a robotic manta ray. Created to
emulate the swimming locomotion of the manta ray for research and surveillance
purposes. The robotic manta ray is capable of swimming at a speed of twice its
body lengths per second for up to 10 hours on a single charge, allowing
researchers to carry out underwater surveillance without disturbing the natural
ecosystem.
Manta rays are considered one of nature’s most
efficient swimmers, possessing a unique propulsion mechanism unlike any other
underwater species. Enabling them to cruise through turbulent seas
effortlessly. The propulsion system of the Manta Ray has inspired many
researchers to try and incorporate similar mechanisms into autonomous
underwater vehicles however the team at NUS have completed the task with
amazing efficiency.
