Scientists from Massachusetts General Hospital, Harvard Medical School and the German Aerospace Center also took part in the study.
The BrainGate team had its first success in 2006. A tetraplegic stabbing victim was able to use the brain-computer interface system to control a computer cursor. John Donoghue says the latest development using robotic arms is a major victory.
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.
Lead investigator Leigh Hochberg says the first time she did it was a magical moment.
"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 15 years, it was an incredible moment."
The research team carried out almost 200 tests with two different robotic arms. The two individuals were able to pick up their target objects 43% to 66% of the time.
The researchers are calling the information very promising. But they say it will take years to fully develop the technology for everyday use.
A report on the BrainGate study appeared last week in the scientific journal Nature.这台计算机安装了专门的软件，可以将信息转化成数字命令来控制其他设备。研究人员使用了高度发达的机械手臂来重现人类的动作。
来自马萨诸塞州总医院、哈佛医学院和德国宇航中心的科学家们也一同参与了这项研究。
“大脑之门”团队于2006年首获成功，顺利帮助一名四肢瘫痪的病人通过脑-机接口系统来控制计算机光标。 多诺霍表示，机械手臂在应用领域的最新进展不亚于一份里程碑式的成就。
一段关于最新实验的视频记录了哈钦森使用机器手臂拿起一杯咖啡的全过程。她把咖啡递到嘴边并用吸管喝到了咖啡。
首席研究员雷·哈奇伯格说，哈钦森首次喝到咖啡的那个瞬间简直就是见证奇迹的时刻。
“看到她伸出机械手臂端起杯子，近15年来第一次自己喝咖啡，那真是个令人难以置信的时刻。”
研究小组使用两种不同的机器手臂进行了大概200次实验。两名瘫痪者使用机器手臂拾起目标物体的成功率在43%到66%之间。
在研究人员看来，这一结果预示着海阔天空的发展前景。但是他们说将这项技术发展成熟继而应用于日常生活还需要若干年。
上周，科学期刊《自然》刊登了一篇关于“大脑之门”的研究报告。
