Brain-computer interfaces are employed for neuroprosthetics, and now in military and defense to control robotic soldiers or fly planes & UAVs with thoughts.

New era has arrived when people  use only their thoughts to control not only themselves, but the world around them. Every action our body performs begins with a thought, and with every thought comes an electrical signal. The electrical signals can be received by the Brain-Computer Interface (BCI), which can electroencephalograph (EEG) or an implanted electrode, which can then be translated, and then sent to the performing hardware to produce the desired action.
