(1). Using the Brain to Move a Robotic Arm
使用大脑思维操纵机械臂
(2). This is the VOA Special English Technology Report.
这里是美国之音慢速英语科技报道。
(3). Cathy Hutchinson is a tetraplegic. She has not been able to move her arms, legs or speak since suffering a stroke nearly fifteen years ago. Recently, she learned how to control a robotic arm using her thoughts. She now can use brain activity to serve herself a drink.
凯茜·哈钦森（Cathy Hutchinson）是一名四肢瘫痪者。自从15年前中风以来，她一直无法活动四肢，也无法说话。最近她学会了如何用思维操纵机械臂。目前她可以用思维（操纵机械臂）给自己倒杯饮料。
(4). The American woman is one of two people who took part in a research project known as BrainGate2. The researchers have spent years studying how to help people who are paralyzed regain movement in their arms and legs.
她是大脑之门2期（BrainGate2）研究项目的两名测试者之一。研究人员花了数年时间研究如何帮助瘫痪者重新获得四肢活动。
(5). John Donoghue is a neuroscientist with Brown University and the Department of Veterans Affairs. He also was part of the project.
约翰·多诺霍（John Donoghue）是一名神经学家，就职于布朗大学以及美国退伍军人事务所，同时也是该项目研究人员之一。
(6). 1:JOHN DONOGHUE: "People who are paralyzed have their brain disconnected from their body. So they are not able to go out and do everyday things that you and I can do, like reach for a glass of water or scratch your nose.
2:So our idea is to bypass that damaged nervous system and go directly from the brain to the outside world so the brain signals can, not control muscle, but control machines or devices like a computer or a robotic limb."
2:So our idea is to bypass that damaged nervous system and go directly from the brain to the outside world so the brain signals can, not control muscle, but control machines or devices like a computer or a robotic limb."
1:多诺霍：“瘫痪者脑部与身体之间的神经连接已经断开，所以他们无法走出去，做一些你我都可以做到的事情，例如伸手拿一杯水或刮下鼻子。
2:我们的想法是绕过受损神经系统，将大脑直接与外部连接，这样大脑信号虽然无法控制肌肉，但可以控制机器或设备，像计算机或机械假肢。”
2:我们的想法是绕过受损神经系统，将大脑直接与外部连接，这样大脑信号虽然无法控制肌肉，但可以控制机器或设备，像计算机或机械假肢。”
(7). The two paralyzed people had small sensors connected to the part of the brain that controls movement. The devices measured brain activity and sent that information to a computer.
这两名瘫痪者被植入了一个连接到大脑中控制运动的部分的小型传感器。这个传感器可以测量大脑活动，并将大脑活动信息发送给计算机。
(8). The computer has special software that turns the information into digital commands for operating other devices. The researchers used a highly developed robotic arm to recreate human actions.
这台计算机安装了了一个特殊软件，可以将这些信息转换为操作其它设备的数字命令。研究人员使用了一个高度发达的机械臂来重现人类活动。
(9). Scientists from Massachusetts General Hospital, Harvard Medical School and the German Aerospace Center also took part in the study.
来自马萨诸塞州总医院、哈佛医学院和德国航空航天中心的科学家也参与了这项研究。
(10). The BrainGate team had its first success in two thousand six. A tetraplegic stabbing victim was able use the brain-computer interface system to control a computer cursor. John Donoghue says the latest development using robotic arms is a major victory.
2006年大脑之门团队首获成功。一名四肢瘫痪者当时能够使用脑-机接口系统控制计算机光标。多诺霍表示，最新进展开始使用机械臂是一项重大胜利。
(11). A video of the latest experiment shows Cathy Hutchinson using the robotic arm to pick up a cup of coffee. She guides the cup toward her mouth, moves it forward and drinks through a straw.
一个最新实验的视频显示，哈钦森使用机械臂拿起一杯咖啡，并把杯子拿到嘴边通过吸管喝到咖啡。
(12). Lead investigator Leigh Hochberg says the first time she did it was a magical moment.
首席研究员雷·哈奇伯格（Leigh Hochberg）说，哈钦森第一次完成这个动作时是一个神奇的时刻。
(13). LEIGH HOCHBERG: "To see her with that robotic arm reach out and pick up that cup of coffee and serve herself that coffee for the first time in nearly fifteen years, it was an incredible moment."
哈奇伯格：“看到她使用机械臂拿起那杯咖啡，近15年来第一次靠自己喝到咖啡。这是一个令人难以置信的时刻。”
(14). The research team carried out almost two hundred tests with two different robotic arms. The two individuals were able to pick up their target objects forty-three to sixty-six percent of the time.
该研究小组使用两种不同的机械臂进行了近两百次测试。这两名瘫痪者都能够（使用机械臂）拿起目标物体，成功率为43%到66%。
(15). The researchers are calling the information very promising. But they say it will take years to fully develop the technology for everyday use.
研究人员称这些信息极有前途。但他们表示，将这一科技充分开发到日常使用中尚需数年时间。
(16). A report on the BrainGate study appeared last week in the scientific journal Nature.
关于大脑之门的研究报告上周发表在《自然》科学杂志上。
