MIT unveils robotic fish that can swim on its own
MIT researches have unveiled "SoFi", a soft robotic fish made of silicone that can navigate independently using its tail and control its buoyancy. SoFi swam in depths of over 50 feet for 40 minutes while taking photos and videos. "This is the first robotic fish that can swim untethered in three dimensions for extended periods of time," said a researcher.
