  介词短语中“to see” 是动词不定式作定语修饰 “ ability” . “ out of …”表示 “ 从…里” . 句中with the ability to see是作全句的状语。

  本句翻译:拥有了这种看的能力,机器人能够识别出不同种类的物体。

  4.One robot vision system uses electronic digital cameras containing many rows of light-sensitive materials.

  一种机器人的视觉系统是用含有光敏材料的数字摄像机制作成的。

  5.When light from an object such as a machine part strikes the camera, the sensitive materials measure the intensity of light and convert the light rays into a range of numbers.

  “ when light from an object such as a machine part strikes the camera,” 是一个状语从句。句中的 “from an object such as a machine part” 是介词短语作后置定语修饰light.

  意为:“当一个物体(如机器零件)上的光线照射到摄像机上时,… …

  主句中“ convert … into” 意思是“把… 转换成…… ”

  例: We converted the small bedroom into a second bathroom.

  The 0 is represented by black. The highest number is white. The numbers in between represent different shades of gray.

  数字“0”代表黑色, “255”代表白色。这两个数字之间的是各种不同灰度的颜色。

  12.It is not yet known whether robots will one day have vision as good as human vision.

  本句的真正主语是 “ whether” 引导的主语从句, it 是形式主语;

  注意此句按照原语序翻译较好。“迄今尚不清楚机器人会不会有朝一日具有人眼那样的视力。”

  技术人员相信要使它变成现实,只能等待若干年之后。
