A helicopter that flies under mind control

 Scientists have developed a mind-controlled system that allows users to fly a model helicopter with just their thoughts

• Researchers at the University of Minnesota in Minneapolis created a brain-computer interface a system that allows the brain to communicate directly with an external device that lets participants control the path of a flying object, known as a quad copter, by thinking about specific movements.
• The interface requires users to wear an electro-encephalography (EEG) cap with attached electrodes that pick up signals from the brain
• When participants think about a specific movement up, down, right or left, for instance neurons in the brain’s motor cortex produce tiny electric signals that are then sent to a computer
• The signal coming from his brain is being picked up by these sensors and then decoded and sent through a Wi-Fi system to control flying quadcopter.
• The computer is going to read that digital signal and do all the processing and extract out the brain signal and control quadcopter.
• The technology could be used to help people with disabilities lead more independent lives.
