Create interface to control a robot drone with the mind
How close we are getting real Control to the brain? It does appear that we are not very far from perfect it. In the most sappy, have been robotic ears and tails responding to brain waves, but we have also recently seen an interesting application, a Chilean company that created a brain Interface for designing 3D printed objects . Also there has been a mind-controlled exoskeletons to help people walk, and even attempts at communication from mind to mind.
A team of researchers from the University of Minnesota has just added another exciting new technology to the list: A drone quadricopter that can perform feats of aerial agility, fully controlled by the thoughts of a person.
Using electroencephalography (EEG), a cap equipped with 64 electrodes, reads the brain’s electrical impulses to control the flying robot. Thinking of making a fist with the left hand, activates certain neurons in the motor cortex of the brain, interprets this pattern encephalographic cap and sends a command to the quadricopter to turn left. Thinking of making a fist with your right hand, is ordered to turn right, and thinking of two fists orders the drone to rise.
By following these guidelines, five people, two men and three women, were able to successfully test the quadricopter quickly and accurately for a sustained period of time, through an obstacle course in the gym of the university.
Professor Bin He, lead author of the study “a quadricopter Control in three dimensional space, using a brain-computer interface based on noninvasive imagerÃa”, hopes the research will be developed to create solutions for people with disabilities.
“Our next goal is to control robotic arms using brain waves, non-invasive, with the ultimate goal of developing brain-computer interfaces that help patients with disabilities and neurodegenerative diseases,” he said.
This would not be the first mind-controlled robotic arm, however, the robotic arm announced in December last year required a brain implant. The solution proposed by Professor Bin He, is much less invasive, and does not require surgery to implant interface.
