MIT unveils robo-fish that can swim 50ft below the surface

A robotic fish might be able to unlock secrets about marine life that is hard for researchers to access, according to a new report. Scientists from the Massachusetts Institute of Technology (MIT) have created a robotic fish called SoFi that was tested in Fiji. SoFi was able to swim more than 50 feet below the surface of the water and for 40 minutes nonstop. The researchers behind the new study, published in Science Robotics, say robotic fish technology could help scientists learn more about organisms that are hard for humans to get to to study. MIT researchers developed a robotic fish that can swim alongside real fish and take photographs of marine life that is hard for humans to access.
