It is becoming more and more important for scientists to closely monitor (监视) our ocean life. However, it is almost impossible since we can scare the animals. Now, thanks to SoFi, the Soft Robotic Fish, scientists may not only be able to keep a close eye on them, but also find undersea secrets that we haven’t known for centuries.
Built by MIT, the snow white robot closely emulates (模仿) real fish, with a soft tail that moves from side to side and two “fins”. To make sure SoFi can freely move around the ocean and swim like a real fish, a hydraulic pump (水泵) moves water from one balloon-like part to the other through SoFi’s soft rubber tail.
During the test in the sea, SoFi swam at the depths. of 50 feet for up to 40 minutes at a time, taking photos. Once in a while, the fish would swim near the strange-looking robot-fish, while at other times they appeared without noticing it.
SoFi now only records videos. The scientists also hope to make it more autonomous (自动的) in the future. “For us, this fish is magical,” says Robert. “We imagine someday it might help us discover the amazing underwater world that we know so little about.”
