Watch: Robotic Fish Can Withstand Ocean Currents, Swim Alongside Real Fish

Earth's ocean is impossibly vast and difficult for humans to thoroughly explore because, well, they cannot breathe underwater. Short of giving people gills, researchers at MIT found a possible avenue to see more of what lurks in the ocean's depths with less human interference, the Los Angeles Times reported. Meet SoFi, a robotic fish made from affordable materials that can be remotely controlled to realistically and effectively swim against ocean currents and near real fish without much trouble. SoFi was originally outlined in detail in a Science Robotics study. It looks like a fish, but it's not.
