Somebody is calling for help in the water. You want to jump in and save them, but that might put you in danger. What do you do?
Soon this won’t be a problem anymore because a robot swimmer called Swumanoid will be on hand to help.
Scientists from Japan designed this robot to swim like an Olympic athlete (运动员). They mapped a swimmer’s body and looked at how every part of the body moves while swimming. The robot can swim just like a human does.
Swumanoid can swim the backstroke (仰泳) and the front crawl (自由泳) at a speed of 0.64 meters a second, about one-third of the world record speed for these swimming styles, according to the Daily Mail.
Motomu Nakashima, head of the team that designed the robot, hopes that robots like Swumanoid can serve as lifeguards in the future.
Besides saving lives, Swumanoid can also be used in swimming research. It can test water resistance, which makes it move more slowly. And it helps to find out how people swim. The information that is collected could help scientists find ways to improve a swimmer’s skills.
Unlike human swimmers, robots don’t get tired from doing the same stroke (泳姿) again and again, so they do not slow down. Therefore, they can collect information more efficiently (有效地).
But the robot is not yet ready to take the place of human lifeguards. Scientists say there are still certain things that need to be improved, such as its motors (引擎) and waterproofing design (防水设计).
