So that's what we're looking for developing.  And we replace the human being -- to go, for example, for measuring radioactivity, you don't want a human to be sailing those robots -- with batteries, motors, micro-controllers and sensors.
那就是我们希望完成的东西 我们还可以替换人类-- 比如，测量放射性物质的时候 你不会想让人类去驾驶那些船 所以就用电池，发动机，微型控制器和传感器来代替人类
