不过，要缩小这些飞行引擎、电池、机械促动器、中控电子装置，以使这些飞行器够轻够小地完美飞行，还是相当困难。

But it remains hard to shrink engines, batteries, mechanical actuators and control electronics to the point where they are small and light enough to fly without impairing their performance.

如智能武器、智能机器人视觉系统以及微型飞行器等，期望整个系统重量轻、体积小、视场大以及对运动目标更敏感。

Such as smart weapons, intelligent robot vision system and micro air vehicles, expected the whole system weight light, size small, large field of view and the more sensitive to the moving target.
