Five years ago,NASA’s rover onMars,spirit,got stuck in sand while exploring the red planet.Recently,another NASA vehicle Mars,curiosity,had to change its path to avoid a sandy area.Scientists realized they needed to find a way to prevent the costly robots from getting trapped in the sand.
So they looked to nature for answers.The researchers brought deadly snakes to a zoo in Atlanta,Georgia.The sidewinder rattlesnakes are native to the southwestern United State.
Theresearchers put thecreatures in a box of sand.The scientis’s video recorded the snakes as they moved sideways up different sand hills their movement is called sidewinding.Daniel Goldman teaches physics at the Georgia Institute of technology in Atlanta.
He says the snakes moved easily in the sand even when the sand was moving Mr.Goldman and other researchers wrote about their findings in the journal science.Theresearchers then performed experiments with a robotic snake developed at Carnegie Mellon University in Pittsburgh,Pennsylvania.MODsnake is one meter long and has 16 parts,or modules.Each part is 6 centimeters wide the robot isknown for its ability to get in and out of tight spaces.
MODsnake helped show why sidewinders climb better than other snakes.Now the researchers are working on the nextgeneration of MODsnake.They hope this sidewinder version will travel through sand well as real snakes do.The robot might be able to explore earth or other planets.It also might be useful in rescue operations.

五年前,美国国家航空局的火星探测器“精神号”在探索火星时被困到了沙子里面.最近,另外一个火星探测仪“好奇号”不得不改变它的路线以免又被沙子吞没,科学家们意识到他们必须想出一个方法来避免这些昂贵的机器被困到沙子里.
  他们向自然寻求答案,这些研究人员将一种致命的蛇带到亚特兰大 乔治亚州的动物园,这些响尾蛇是美国西南本地的.
  研究人员将这些蛇放进装着沙子的盒子里,科学家用录像记录这些蛇的行为,当它们横着爬到不同的沙堆上的这种行为叫做旁绕,丹尼尔.高盛在亚特兰大的乔治亚州理工学院教物理,他说那些蛇很容易在沙子里爬行即使那些沙子是流动的,高盛先生和其他的研究人员在科学杂志上发表了他们的发现,然后这些研究人员用卡内基梅隆大学研发的机器蛇做实验,这只机器蛇有1米长并且有16个部分,或者说是模块,每部分有6厘米宽,这个机器蛇以它能出入狭小空间的能力而出名
  这个机器蛇解释了为什么角响尾蛇的爬行能力比其它蛇要好,现在研究人员正在研发第二代机器蛇,他们希望这只模拟的角响尾蛇能像真的角响尾蛇一样很好地穿过沙子,这种机器蛇或许能够探索地球和其它星球,可能在救援行动中也能派上用场.
