While many robots are programmed to do a specific task, this robotic leg works differently.
尽管许多机器人按照程序设定可以做具体工作，但这个机器人腿的工作方式很不同。
What's different here is that the robot is not trained to do anything in particular.
它的不同之处在于这个机器人没有接受任何特别事情的培训。
It just knows how to learn. Through an algorithm inspired by biology,
它知道如何学习，通过生物学所启发的算法，
this robotic leg with animal-like tendons is controlled by artificial intelligence.
这个机器人腿是由人工智能控制的，它有着像动物一样的肌腱。
It can learn to walk within five minutes of "free play."
通过五分钟的“自由玩耍”时间，它可以学着如何走路。
It can also learn to adapt to other movements without any additional programming.
它还可以学着适应其它环境，而无需额外程序。
Just the way a baby tries to pull different muscles and see how it moves its you know, limbs
就像婴儿试图拉动各部位肌肉，看肌肉是如何移动四肢，
and try to kind of, find an understanding about how to control them by that which we call motor babbling,
尝试着寻找，懂得通过肌肉来控制四肢，我们称之为“牙牙学语”，
our system tries to pull on different motors and observe how it effects its movements.
我们的系统尝试着做各种动作，观察它是如何影响移动的。
A robot with this algorithm can be trained similar to how a dog can be trained. In this case, with the help of sensors.
有了这种算法的机器人可以像狗一样接受培训，而对于机器人，我们需要传感器的帮助。
When the leg pushes the belt backwards, this rotation in angles is a number that is given to the algorithm saying "we like that."
当它的腿将传送带推向后方时，这个角度的转动给了算法一个信号，那就是我喜欢这个。
If it moves in the opposite direction we say "we really don't like that."
如果它向相反方向移动，我们说我们真的不喜欢这样。
Creating a self-learning robot can be inexpensive with the help of this.
通过传感器，创造自学机器人一点都不贵。
We design it and after that we 3-D print it.
我们设计完后就通过3D打印出来。
One possible application in the near future is to help people with a physical disability.
在不久的将来，它最有可能使用在残疾人身上。
Either augment your capabilities or help you if you're too weak.
它或者可以增加你的能力，或者可以在你很虚弱时帮助你。
Another possible use in the future is to help in disaster areas where a robot leg can adapt to different terrains.
未来它的另一个可用之处是帮助救灾，机器人腿可以使用各种地形。
Researchers say they envision self-learning robots to one day help in space exploration.
研究人员称他们预想着有一天自学机器人可以帮助太空探索。
They say robots that can adapt to its environment can potentially be available within a few years.
他们称能够适应太空环境的机器人有可能在几年内出现。
