一只能在光滑垂直的墙壁上爬行和天花板上横越的机器蜗牛开始缓缓移动了。这只机械软体动物是由安妮特·霍索伊领导下的马萨诸塞理工学院的工程师小组研制而成。他们制造这个机器蜗牛是为了测试蜗牛贴着物体表面行走的数学模型,但他们也希望机器蜗牛有一天能在现实生活中派上用场。 A snail crawling on a smooth vertical wall and traversing the ceiling began to slowly move. This mechanical mollusc was developed by the Massachusetts Institute of Technology Engineers team under the leadership of Annette Hawthorne. They made this machine snail to test the mathematical model of the snail walking on the surface of the object, but they also hope that the machine snail will come in handy in real life one day.
