The ability to recognize and harness brain activity has exciting potential. This technology can help quadreplegics move prosthetic limbs or allow people with severe spinal cord injuries to interact with their environment. A few years ago, Crawford and his colleague, Brain-Drone Racing League cofounder Marvin Andujar, dreamed up the idea of using this approach in drone racing. “Marvin and I were working on human-centered computing at the University of Florida,” Crawford recalled, “and we realized that we could use drone racing to encourage people from around the country to get involved in brain-computer interface.” Around the country turned into around the world. “Shortly after the first race in 2016, we began getting emails from students all over the globe interested in building their own brain-drone race events.”

For Crawford, the excitement comes from seeing people participate from outside the usual world of academic computer science. “Hackathons and makers spaces have set the stage for people to get involved in this who have not had that opportunity before” he said. Affordability has been key to this growth. “Not long ago,” Crawford recalled, “you had to have a lab and a big budget. Now you can tinker with this stuff in your garage for a couple of hundred dollars.” Software advances have also made experimenting with brain computer interface a lot easier. “Open source software like the Robot Operating System has introduced this modular way of building robot systems that simplifies the design process.”
Brain-controlled systems still have some hurdles to overcome. Advances in neurotech hardware are needed, such as EEG headbands with better spatial resolution to discriminate between signals, and software improvements like better models to detect particular patterns of brain activity. “But our biggest challenge,” Crawford said, “is helping people understand what it can and can’t do. This headband is not reading your mind or invading your privacy, it’s not sending signals into your brain and manipulating your thoughts. It can do a lot of cool stuff, but it can’t do that.” As people learn more and understand what brain computer interface really means, the field will open up and grow exponentially. “We are right on the edge of an explosion of novel applications,” Crawford predicted. “When we get a diverse group of people using this technology and thinking about ways to apply it, we’ll get something a group of computer scientists would never even have thought of.”

Recently, moving items with your mind was the province of Jedi knights and young boy wizards. However on April 6, rivals and viewers will come down on the University of Alabama in Tuscaloosa for the Brain-Drone Race competitors, in which rivals will race drones by moving them just with their minds. Mind-reading drones might look like a heading that belongs together with alien kidnappings and grassy knoll theories, however the truth is even more fascinating.
Chris Crawford, cofounder of the Brain-Drone Racing League, showed the science behind the magic at his computer technology laboratory at the University of Alabama. His trainee volunteer, seated in front of a computer system, uses a cap that covers his head. “This is an EEG display, which discovers electrical activity in the brain,” Crawford discussed. “When you choose to move your arm,” Crawford continued, “the motor cortex of your brain sends out a signal to your muscles.” The motor cortex, where motions are prepared, goes approximately from ear to ear over the top of your head. Each part of the motor cortex represents a specific part of the body. For instance, the motor cortex an inch approximately above your right ear manages your left hand. That specific part of the brain illuminate when you think of moving your hand. Electrodes on the cap sense the activity, and send out the signals to a computer system. Naturally, other parts of your brain are ideally active also, so the aggregate signals are sent out through computer system algorithms that discover specific patterns of activity. “We do not desire the pilot to really move, since that develops a great deal of electrical sound,” Crawford stated. “We simply require him to truly focus on moving his hand, or pressing something forward, or clenching his fist. It truly does not matter what motion we pick, as long as it develops an electrical signature that we can discover and determine.” When the computer system believes it is at least 80% most likely that the signal was from the motor cortex representing the pilot’s left hand, it will send out an electrical signal of its own to the drone, advising it to move on.
Saturday’s drone racers will not use complete caps, however rather headbands that walk around the pilots’ foreheads. The headbands are less expensive and much easier to utilize, which is a huge benefit for little groups, however they can’t discover organized motions. Rather, they utilize the strength of brain activity associated to concentration. “There are various brain wave frequencies that represent various frame of minds,” Crawford discussed. “We utilize beta and gamma waves, which represent attention and high levels of psychological processing. So we have the pilots do psychological mathematics that needs a great deal of concentration, and the drones will move on based upon the strength of those brain waves.” It’s not proper responses that move the drones forward, however rather the strength of the brain waves the pilots create by focusing. “We are still attempting to comprehend the qualities that make somebody an excellent ‘brain-drone racer,'” stated Crawford, “however their capability to stay concentrated and shut out diversions from the sound brought on by the drones, crowd, and rivals typically affect their efficiency.”
