Abstract : (Seminar) The core of this paper is that to operate machines from a remote area . In the given BMI DEVELOPMENT SYSTEMS the brain is connected to client interface node through a neural interface nodes . The client interface node connected to a BMI SERVER which controls remote ROBOTS through a host control .a BMI development system.BRAIN STUDY:In the previous research, it has been shown that a rat wired into an artificial neural system can make a robotic water feeder move just by willing it. But the latest work sets new benchmarks because it shows how to process more neural information at a faster speed to produce more sophisticated robotic movements. That the system can be made to work using a primate is also an important proof of principle. Scientists have used the brain signals from a monkey to drive a robotic arm. As the animal stuck out its hand to pick up some food off a tray, an artificial neural system linked into the animal's head mimicked the activity in the mechanical limb.It was an amazing sight to see the robot in my lab move, knowing that it was being driven by signals from a monkey brain. It was as if the monkey had a 600-mile- (950-km-) long virtual arm. The rhesus monkeys consciously controls the movement of a robot arm in real time, using only signals from their brains and visual feedback on a video screen. It is said that the animals appeared to operate the robot arm as if it were their own limb. The technologies achievement represents an important step toward technology that could enable paralyzed people to control "neuroprosthetic" limbs, and even free-roaming "neurorobots" using brain signals.Importantly ,the technology that developed for analyzing brain signals from behaving animals could also greatly improve rehabilitation of people with brain and spinal cord damage from stroke, disease or trauma. By understanding the biological factors that control the brain's adaptability. The clinicians could develop improved drugs and rehabilitation methods for people with such damage.The latest work is the first to demonstrate that monkeys can learn to use only visual feedback and brain signals, without resort to any muscle movement, to control a mechanical robot arm including both reaching and grasping movements.
