Paralyzed women use brain commands to control the robot to make themselves drink coffee.

Casey's brain was implanted with a chip that was 4 millimeters long and wide. A total of 96 electrodes on the chip are connected to the nerves in the brain that control motor function.

2 the signal line connects the chip to the external computer.

When Casey's consciousness of drinking coffee appeared in her brain, it was transmitted to the computer that controls the robot through the chip and signal line.

The computer read Kathy's consciousness and issued instructions. The robot sent the coffee bottle to Kathy's mouth. Kathy opened her mouth and was very happy after drinking the coffee.

For some severely disabled people, because the limbs can not be used flexibly, there are many inconveniences in life, so it is necessary to have special personnel to serve them. However, a new scientific and technological achievement made by US researchers may greatly facilitate the lives of people with disabilities, who can use this technology to enable a special robot to execute his brain instructions as long as they want to do something. A woman in the United States who has been paralyzed for 15 years drank hot coffee without help for the first time in 15 years. If this technology can be widely used, people with disabilities all over the world will get the good news.

According to the Daily Mail of May 17, Hutchinson Casey, who has been paralyzed for 15 years, drank hot coffee for the first time without help, but that doesn't mean she can move her limbs. but with the help of a new study by researchers. According to this latest scientific research, as long as Kathy's brain gives instructions, the robot will help her achieve it.

According to Dr. Lehkebo, a neuroscientist at Brown University and Harvard Medical School who led the research, the researchers first implanted a chip in Casey's brain that is four millimeters long and wide. There are 96 electrodes on the chip, connected to the nerves in the brain that control movement, once Casey has any ideas. Her consciousness will be transmitted through the chip to a nearby computer that controls the robot, which is linked by a signal line placed on Kathy's head. In the experiment, Kathy's idea was to drink a cup of coffee, and the chip passed her idea to the computer, which then sent instructions to the controlled robot, which reached out its manipulator, grabbed the coffee bottle, and sent it to Kathy's mouth. Casey opened her mouth and drank coffee without help for the first time in 15 years.

"We were so moved by the smile on her face that we will never forget that moment." Dr. Huckaber said the results of this study will greatly change the lives of many people with disabilities, allowing them to restore some of their independence. It is reported that Casey, who lives in a private nursing home in Boston, Massachusetts, is one of two volunteers who participated in the team's experiment. Another volunteer was an old man with a stroke in his sixties.

It is reported that the latest scientific research will be published in the next issue of the journal Nature, which is also the greatest achievement in decades in helping people with disabilities restore their motor function. However, this scientific research remains to be improved, and in the experiment on Casey, she drank coffee from the robot four times and failed twice. Nevertheless, the researchers are still confident about it. Kevin Warwick, who began working on implanting chips into the brain a decade ago, said that by improving and developing the results, people with disabilities will be able to turn off lights, open doors, move wheelchairs and even drive their own cars.

"even for people who are severely paralyzed, we may be able to help them through technical means to brush their teeth in the future." When it comes to the prospect of this scientific research, Dr. Huckaber is full of confidence. It is reported that this research has received strong support from many institutions around the world, including the US military, the German Space Research Center and some world-famous universities and scientific research institutes.
