The developer of the world's most advanced bionic leg says, "I don't see disability; I see bad technology." 全球最先進的仿生腿研發者說：「我的眼裡看不到殘疾，我看到的是不良的科技。」
Hugh Herr is devoted to designing better prosthetics. 休．赫爾致力於設計更好的義肢。
And as part of CNN's new show called The Art of Movement, Nick Glass traveled to the Massachusetts Institute of Technology to learn more. 在本台新節目《動的藝術》中，尼克．葛拉斯前往麻省理工學院了解更多。
Hugh Herr is a boyish 48-year-old professor of biomechatronics at MIT's Media Lab. 四十八歲的休．赫爾任職於麻省理工學院媒體實驗室，是個模樣稚氣的生物機電工程教授。
He's helped develop something absolutely extraordinary, the world's most advanced bionic leg. 他協助開發一項非常了不起的東西，那就是全世界最先進的仿生腿。
So, can I actually see this new bionic leg? 那麼，我可以實際看一下這隻新的仿生腿嗎？
Sure. 當然可以。
Both of his own legs are artificial. 他本身的兩條腿都是人造的。
So, what you see here is a chunk of aluminum and titanium and silicone. It's powered; this is the battery. 你看到這裡是一大塊鋁、鈦和矽。它有動力，這是電池。
What happens is, when I walk, it powers my movement from step to step in the same way that your calf muscle is controlled by your spinal cord. 是這樣的，我走路的時候，它會帶動我每一步的動作，就像你的小腿肌肉受到脊椎神經控制一樣。
So, we've actually captured the essence of how the lower leg works. 所以說，我們已經掌握住小腿運作的精髓了。
In 1982, at the tender age of 17, Hugh Herr lost both his legs to frostbite, trapped climbing in a blizzard. 一九八二年時，在他稚嫩的十七歲那年，休．赫爾登山因暴風雪受困，他的雙腿因為凍瘡而截肢。
I went back to climbing with specialized artificial limbs. 我穿著特製的人工義肢回去登山。
And after a year, I was climbing better with the artificial limbs that [than] I achieved with biological limbs before the accident. 一年之後，我用人工義肢登山的技術，比我在意外發生之前用原生下肢爬山的技術更好了。
And this was just an awakening, 'cause I realized that technology can heal, it can rehabilitate, 這就像是一種覺醒，因為我理解到科技可以療癒，可以復健，
and in my own case it actually could extend my physicality. 而以我自己的例子來說，它實際上還提升了我的體能條件。
Light and flexible, the bionic leg moves as elegantly as the real one, as if the wearer still had calf muscle and an Achilles tendon. 仿生腿重量輕且具彈性，又能和真腿一樣能優雅地動作，就好像穿著仿生腿的人依然擁有小腿肌肉和阿基里斯腱一樣。
Twelve sensors to measure force, position, speed. Three microprocessors tell the leg how to perform. 共有十二個感應器測量力道、位置和速度。有三個微處理器告訴腿要如何動作。
And in the ankle, a device that behaves exactly like a muscle. 在腳踝處有個裝置能做出和肌肉完全相同的反應。
When I go faster, it gives me more energy. 我走得比較快時，它就能提供我更多能量。
When I go up a hill, it gives me even more energy. 我爬坡的時候，它能給我更多能量。
When I go down a hill, it takes energy out. It brakes automatically for me. 我往下坡走的時候，它會減低能量。它會自動幫我煞車。
I see an extraordinary beauty when that intimacy occurs between human and machine. 當人類和機器之間產生親密關係時，我看到了其中非比尋常的美。
They should be beautiful, but they need not have a human beauty, they could have a machine beauty. 這些義肢應該是美麗的，但它們並不需要擁有人類的美，它們可以擁有機器的美。
Some 600 amputees, many of them American soldiers, have been fitted with these legs. 約有六百名截肢者，其中許多是美國軍人，已經安裝了這種義肢。
They aren't cheap. Hugh Herr's pair cost $120,000. 它們所費不貲，休．赫爾這一雙義肢要價十二萬美元。
People aren't disabled; technology is disabled. I just... I don't see disability at all. I see bad technology. 殘障的不是人們，而是科技。我就……我完全看不到殘疾，我看到的是不良的科技。
If someone tapped you on the shoulder and said you can have your original limbs back, what would you say? 如果有人拍拍你的肩膀說，你可以要回你原生的肢體，你會怎麼說？
Absolutely no, absolutely not. It's fun having a body part that you can freely manipulate. 絕對不，絕對不要。能有一部份的軀體可以任意操弄是件很有趣的事。
You know, from my knees down, I'm a blank slate. I can create anything. 我膝蓋以下的地方都是張白紙，我可以隨意創作。
I can build legs with wings if I wanted to. That's a lot of fun. 只要我想，我可以打造出有翅膀的腿。這太有意思了。
You look like you belong up there. 你看起來好像在上面怡然自得。
I've climbed since I was six, seven years old. To me, it's as simple as walking. 我從六、七歲起就開始攀岩了，對我而言，攀岩就像走路一樣簡單。
It's something balletic. 好像在跳芭蕾舞一樣。
Did I get a 10? 我拿到十分滿分嗎？
