Who would have thought that snakes will someday be made robotic? And a water / sea snake at that! Here’s what the video submitter has to say about their amazing project:

“Why can snakes move ahead on without legs?” From this problem, we started research of snake biomechanisms, which resulted in the “Why can snakes move ahead on without legs?” From this problem, we started research of snake biomechanisms, which resulted in the development of “Snake Robots”. Snake Robots have many possible applications, even though the structures are simple. Hirose Fukushima Robotics Lab”
