He Bin, a professor at the University of Minnesota in the United States, led a team to develop a quadrotor helicopter that can be controlled by mind. He Bin said that this is the first time human beings can control the flight of a flying robot through their own ideas. In the experiment, five participants successfully controlled the flight of the helicopter. The average linear speed of the quadrotor helicopter was 0.69 meters per second. Participants sat in front of the screen showing the helicopter flight picture. Their brain signals are recorded by electroencephalography and transmitted to helicopters via WiFi. According to foreign media reports, American scientists have developed remote-controlled helicopters that can be controlled by mind. The development of such helicopters is only the first step. They hope to develop robots that will enable the patients of the degenerative and neurodegenerative diseases to regain their independent living ability in the future. Bin He, a professor at the University of Minnesota, said that this is the first time humans have been able to control the flight of a flying robot through their own ideas.
The helicopter developed by scientists in Minnesota is a four-rotor helicopter. In the experiment, five participants successfully controlled the flight of the helicopter. The quad-rotor helicopter has an average linear speed of 0.69 meters per second. The researchers used a screen to display a picture of a four-rotor helicopter onboard camera, and participants were placed in front of the screen to let them clearly see the direction of the helicopter. Their brain signals are recorded using EEG and transmitted to the helicopter via WiFi.
Researchers asked participants to imagine using their right hand, left hand, or both hands. These ideas were converted into orders, commanding the helicopter to turn right, turn left, take off and land. Subsequently, they asked participants to control the helicopter through two foam rings suspended under the ceiling of the stadium, observe their performance, and then score their performance by analyzing the statistics.
In a controlled experiment, participants used the keyboard to control the helicopter. Through these two different experiments, scientists were able to compare standard control methods with mind control. He Bin said: "In the previous study, we have confirmed that human beings can control a virtual helicopter through their ideas. I originally decided to use a small helicopter for this kind of research, but in the end I chose a quadrotor because This type of helicopter is more stable and safer."
Currently, scientists in Minnesota are using this technology to find ways to help restore hearing, vision and athletic ability. To put it bluntly, it is to build a bridge between the brain and external devices. He Bin said: "Our next goal is to use non-invasive brainwave signals to control the robotic arm. To achieve this goal, we need to develop a brain-computer interface that will benefit patients with delirium or neurodegenerative diseases."
