Robots have evolved in leaps and bounds in recent years, but they still cannot safely leap or bound.
近幾年機器人得到了跳躍式的發展，但在安全地進行跳躍活動方面卻一直止步不前。
They have to move carefully.
它們只停留在小心謹慎移動的范疇。
If a robot were to fall from an elevated surface, for the most part it would crash down like a bag of rocks.
如果機器人從一個較高的地方跌落，大多數情況下會像袋石頭一樣。
Not ideal if that robot is on a rescue mission.
而如果該機器人在執行救援任務，后果會不堪設想。
So a team of Georgia Tech researchers wants to produce robots that are more agile, by making them literally cat-like.
因此喬治亞理工學院的一組科研人員希望能制造出更為靈活的機器人，或者說把它們做得像貓一樣。
Specifically, the plan is to create a robot that can emulate a cat's uncanny ability to calculate the best landing angle, adjust its body midflight and land on its feet.
具體說來，這些研究人員的計劃是設計出模擬像貓一樣估計最佳著陸點、調整身體用腳著陸的具有“神秘能力”的機器人。
So far the research team has been able to build a robot capable of computing landing angles during test falls.
目前這個小組已成功造出一個能夠在跳躍測試中計算著陸角度的機器人。
They hope to eventually give the robots joints that can twist or flip their bodies to stick the landing, regardless of the angle.
他們希望最終給機器人安裝能夠進行彎曲、翻轉的關節，讓它們可以不用考慮角度問題安穩著陸。
To do that, they'll need better motors and servos.
為了實現這個目標，他們需要更好的馬達和伺服系統。
The ones available today are not fast enough to sufficiently adjust a robot's body in real time.
而現有的馬達和伺服系統運算并不快，不能實時調整機器人的身體。
Baby steps. David Belle didn't develop the cityscape acrobatic activity known as Parkour overnight.
目前這只是起步階段。大衛貝勒也沒有在一夜間搞出諸如跑酷般的城市雜?；顒印?/div>
And the typical house cat has had tens of thousands of years to perfect the soft landing.
而傳統的家庭養貓咪的完美軟著陸則有幾千年的歷史。
