Recently, Cheng Hong, executive director of the Robotics Research Center of the University of Electronic Science and Technology, developed a fourth-generation exoskeleton robot to help paraplegic patients with spinal cord injury walk like normal people.

"China is the fourth country to successfully develop exoskeleton robots after the United States, Israel, and Japan." Cheng Hong said that the development of exoskeleton robots is not a "single soldier" in a certain discipline, but a mechanical structure and medicine. The high degree of cross-integration of human factors such as engineering and computer technology. The fourth-generation exoskeleton robot they developed is made of aerospace aluminum. It is about 1 meter high and weighs about 23 kilograms. It has 6 joints and 7 sensors from top to bottom. When the user wears it, wear it on the chest, abdomen, and leg straps, and put a pair of crutches on the arms. When in action, the lumbar sensor transmits the information to the computer by testing the user's upper limb inclination and tilt acceleration, and transmits the information to the computer, and then transmits commands to the robot through the control module to realize electric drive joints, smart shoes, lumbar support and binding. The operation of the attachment assists the user in action. When moving forward, the user's legs and feet are slowly lifted by the electric drive joints and smart shoes, and the crutches cooperate in time to complete the walking action.

“The fourth-generation exoskeleton robot technology has already ranked among the best in the world.” Research and development team member Hou Lei said that compared with previous generations of exoskeleton robots, the fourth generation can automatically identify and plan gait through smart shoes and other sensors to complete the stairs. Up and down, walking faster and more smoothly. At the same time, with artificial intelligence algorithms, the exoskeleton automatically recognizes the wearer's intention, and the human-computer interaction is more coherent and natural.
