When I do, you can see the actuator respond by curling up.

大家到，促器做出了蜷缩反应。

This is one of our actuators, and I'm applying a voltage to it.

这是我们使用的促器之一，我现在给它施加一定的电压。

If you want legs for your tiny robot, you need actuators, parts that move.

如果想要让小机器人有腿，需要促器和会的零部件。

Well, the actuator is made from a layer of platinum just a dozen atoms or so thick.

促器是用只有一打原子差不多厚的一层铂制成的。

They are stimulated and motivated by discipline and direction.

他们受到纪律和上级指令的激励和促。

She placed her hand to her forehead and breathed heavily; and then her rich, romantic lips parted under that homely impulse—a yawn.

她把手搭在前额上，喘着粗气；然后在那本能习惯的促下，她那两片丰润而浪漫的嘴唇分了开来——打了个哈欠。

So here's a couple thousand or so actuators, and all I'm doing is applying a voltage, and they all wave, looking like nothing more than the legs of a future robot army.

这里大约有几千个促器，我现在所做的是施加电压，于是它们会摇摆，起来像是未来机器人军团的腿。

Then your actuator is flexible enough to bend to these small sizes without breaking, and it can use the forces that come about from just attaching or removing a single layer of atoms.

而且促器要有足够的灵活性，即能做到微观层面的弯曲，不会断裂，同时，它利用附着或移除一层原子所产生出来的力。
