A robotic sea turtle that features a large waterproof torso and can pack in a bunch of sensors is being developed by researchers to boost autonomous underwater navigation and rescue. The prototype unveiled at the Swiss Federal Institute of Technology is several feet long, primarily made of aluminium, and can move a meter per second, which translates into 6.6 feet. According to the specifications, each fin of the robot contains three actuators for 3-D movement and has a diving depth of more than 300 feet, the ‘Discovery News’ reported. The robotic sea turtle could have several key advantages over ‘robot fish’, including extra manoeuvrability, capability and speed along with being able to hide high-tech gadgetry under the shell. The turtle can help detect pollution and lead sea animals away from danger.
While the robot-turtle can be controlled remotely, it’s primarily intended to push the limits of autonomous underwater navigation. Mechanical engineers at the Swiss Federal Institute have been working hard on the robotic sea turtle project called “Naro-Tartaruga” since 2008. According to ‘IEEE Spectrum’, the latest prototype will finally be heading for its first open water dive later this month.
