In the future, paralysis patients may be able to have the same mobility as normal people, which is not a fantasy. A few days ago, CCTV's original large-scale science and technology challenge program "Witty" was broadcast, and Huang Man, a Mianyang policewoman who was paralyzed for 12 years, realized the "dream of standing" for 12 years through mind control and exoskeleton robot.
Huang Man, who had been paralyzed for 12 years, finally stood
The Chengdu Business Daily reporter learned that the exoskeleton robot that helped Huang Man realize his dream was developed by the University of Electronic Science and Technology. Yesterday, the Chengdu Business Daily reporter learned from the University of Electronic Science and Technology of China that this "exoskeleton robot" that helped disabled people "stand" and resembled the lower limbs of the human body has now been upgraded to the fourth generation. It not only helps patients stand, but also allows patients to go up and down stairs, and even automatically calculates the height of the steps and plans gait. It is understood that this exoskeleton robot controlled by the mind is also the prototype of the fifth generation of EEG exoskeleton robot, which is still under development and improvement.
The relevant person in charge of the R & D team said that this "fourth-generation exoskeleton robot" made in Sichuan is a typical example of scientific and technological development to help social progress, and it is also a remarkable achievement in the intelligent transformation of human-computer interaction. In the future, the robot will contribute to serving the social economy and ensuring health.
accidentally
Car accident paralyzed policewoman for 12 years Husband "wants to one day stand and hug her"
A car accident on the wedding day 12 years ago made Huang Man, a female police officer at the Mianyang Fucheng Public Security Bureau, a high paraplegic. For the next 4,400 days and nights, she was confined to bed, unable to take care of herself. The diagnosis given by many hospitals is that she has been unable to stand and walk in this life.
Although her husband at the time chose to leave for various reasons. However, the optimistic Huang Man did not give up on life, let alone give up on himself. She taught herself as a psychological counselor and came to the disaster site in a wheelchair during the 2008 Sichuan earthquake to conduct psychological counseling for the local people.
Huang Man's strength and bravery also allowed her to harvest a new relationship in 2011 and enter the marriage hall with her current husband Guo Qiang. Since then, thousands of days and nights of companionship and care, every day the husband has to pick her up and put her down twenty or thirty times, often tired and sweaty. He took her to visit many famous doctors. Doctors said that from a medical point of view, it was almost impossible for Huang Man to stand up. Guo Qiang has been reluctant to give up hope, and his biggest wish is: "I want to be able to stand and hug her one day."
Come true
Exoskeleton robots resemble human lower limbs and can go up and down stairs with mind control
In order to help Huang Man and Guo Qiang realize their dreams, the exoskeleton robot research and development team of the Robot Research Center of the University of Electronic Science and Technology of China decided to use a brain control device to let her control the module through brain waves, so as to convey instructions to the exoskeleton robot, and help it stand with the help of an exoskeleton robot that resembles the lower limbs of the human body.
Professor Cheng Hong, head of the research and development team, said that the use of exoskeleton robots is manifested in two aspects, one is for people who need compensation for rehabilitation, and the machine carries people's joints to move; on the other hand, the machine moves with the movement of normal people. The set of equipment used by Huang Man can assist her to walk according to the normal human bionic gait, carry out rehabilitation training, and help her go up and down the stairs normally. Through a helmet, Huang Man's brain nerve signals can be detected, and the signals will be transmitted to the exoskeleton robot, which acts according to the patient's thoughts, so as to achieve standing and walking.
So how do you control an exoskeleton robot with your mind? Professor Cheng Hong introduced that this is a brain-computer interface technology, is a real-time communication system that does not rely on peripheral nerves and muscles, it establishes a direct connection between EEG signals and robot equipment, and realizes the control of peripheral devices by decoding and recoding the drive source signal. To put it bluntly, "mind control."
Because Huang Man's brain signal is very weak, he has failed many times in training. The R & D team adjusted the program many times, and through countless attempts and efforts, Huang Man, who strengthened his training, finally stood up through the mind control exoskeleton robot and fulfilled the dream of "standing" for 12 years.
Pre-sale
The third generation of exoskeleton robots can be pre-sold Bare metal costs about 200,000 yuan
The Chengdu Business Daily reporter learned that the research and development of exoskeleton robots of the University of Electronic Science and Technology began in 2010. Professor Cheng Hong, who recently returned from the United States, led the team from scratch, and in only 5 years, it took only 5 years to achieve a wear test on the patient, which is 1/3 or even 1/6 of the foreign exoskeleton robot research and development cycle. It has also made China the fourth country to successfully develop exoskeleton robots after the United States, Israel and Japan. "At present, more than 100 patients have tried exoskeleton robots." Cheng Hong introduced that the current fourth-generation robot can sense the human body's movement intention through sensors, and then quickly transmit the information to the computer, and communicate the command line through the control module. Cheng Hong said that this robot can also help patients go up and down stairs, it will automatically calculate the height of the steps, plan the gait, and ultimately help users complete the action of going up and down the stairs.
Surprisingly, the third-generation exoskeleton robot is now available for pre-sale. The price of bare metal is about 200,000 yuan (excluding any pre- and post-production manual training and nursing fees). However, the third generation of robots does not have the function of going up and down the stairs, nor can it be controlled by the mind, and can only realize the function of assisting walking. At present, Professor Cheng Hong's team is developing the fifth generation of exoskeleton robots, which will achieve complete control of exoskeleton robots with brain consciousness to execute instructions, which will be a major breakthrough in artificial intelligence. In the future, the robot is expected to contribute to the social economy and health protection on a broader scale.
