百科知识视频之煎蛋小学堂70 如何驾驶好奇号火星车

How do rovers drive on Mars? First of all there's no joystick for driving a Mars rover,Before a rover "hits the road".Engineers send computer commands overnight,Telling it where to go the next day,Depending on how tricky the terrain is Rover drives have two options.

探测器如何再火星上漫游?首先 驾驶好奇号可没有操纵杆可用 在好奇号上路之前 工程师会在头天晚上下达指令 告诉它第二天要去的地方 根据地形的棘手程度 驾驶员可有两种选择.

They can send a string of specific commands like:Drive forward five meters;then turn right 90 degrees,The rover turns its wheels enough times to add up to five meters,And then turns in place,Or if it looks safe,They can let the rover think on its own,They write commands like:See that rock over there?

他们可以发送一条特定的指令比如：向前直行5米 然后右转90度 好奇号开始转动轱辘直到累计达到5米远 然后原地转向 或者在没有危险的时候 他们可以让好奇号自己想法子 他们会给出这样的指令：奇奇，看到那块石头了么?

Find your way there safely,Then using two cameras like human eyes,The rover gets a 3D view of hazards,Such as large rocks and steep slopes,After mapping the danger zones,It plots the safest route to avoid them,Either way,Did the rover complete its drive as planned? Engineers double-check when the rover sends back A postcard of its new spot on Mars!

自己找条安全的路过去吧 他们使用了如人眼一般的两架相机 好奇号便可以得到一个三维视角 在绘制完有大石头或陡峭山坡 这样的危险区域的地图后 它找出最安全的一条路开避开危险 无论哪种方式 好奇号最后是按计划完成任务了么?工程师会根据好奇号传回的明信片 再次它在火星上最新的位置!
