When the pressure goes up, this shaft just pulls on it, pulls on the metallic tendon, and that pulls on the joint to make its arm to go forward for example, or back. So, you can see these cylinders going in and out as he moves his arm up and down."
当压力升高时，活塞就往里推，从而推动金属零件，进而推动机器人的关节，使胳膊或后背向前运动。因此，当它提起或放下胳膊时，你会看到这些液压缸在里外活动。
All those components are pretty heavy.
所有的这些组成部件都很沉重。
"When he's fully configured with power systems, he can weigh up to 450 pounds."
“当装上电力系统，配置齐全的时候，他体重就会达到450磅。”
But it won't take a superman to put on this super device. It is engineered to feel light on whoever wears it.
但是要穿上这套设备，并不是只有超人才行。只要一开动引擎，谁穿上它都会感觉轻松。
"He can feel the mass of 450 pounds, but he doesn't feel the weight. I can move the system around now just with my fingers, if I use his input. So, it basically floats. When he picks it up though again, and I've tried to push on him and he pushes on me, he has great strength. So the key is he can put out large forces, but he doesn't have to use much effort to do that."
它能感受到450磅的质量，却感受不到重力。如果利用它的输入功能，我可以只用手指便能移动这个系统。它基本上是漂浮着。当它再次抬起重物时，我推它，他也推我，它的力量很大。所以重点在于它能不费吹灰之力对外界施加很大的力量。
How much can an Exoskeleton lift? How much do you want to lift?
Exoskeleton能举起多重的重物呢？而你想举起多重的重物呢？
"The computer can decide to have anywhere from zero to 3,000 pounds per square inch inside the cylinder. So the loads these cylinders can hold can be 1,000 pounds."
“计算机会决定液压缸内每平方英寸承受零到3000磅的重量。所以这些液压缸能承受质量为1000磅的重物。”
This super strength could come in handy in an emergency.
这种超能量可以在紧急情况下派上用场。
"Now there's many applications for the Exoskeleton in life-saving activities, and going into situations where you extract people that are injured, or where you move material that's hazardous to people."
“如今已为Exoskeleton开发出用于救生活动的软件，并应用到现实社会中去，比如将受伤群众送往安全地带，或者移动对人类有害的物质材料。”
And the military wants to use it to take the pain out of heavy lifting.
而且军队也希望利用它来解除大型起重的痛苦。
"Many times with aircraft and other vehicles, you want to load munitions into them and they are heavy. And if you have to keep doing that all day, you'll get very tired. So, this is an issue of endurance."
“许多次，你想利用飞机和其它交通工具来搬运沉重的军火武器。一整天下来，你会精疲力尽。所以这也解决了耐力的问题。”
