Cyborgs are part human and part robot. The first legally recognised cyborg is a man named Neil Harbisson in Britain. He attached an antenna to his skull that allows him to identify colours around him based on vibrations that his brain is able to recognise. Engineers in America have also created a robotic arm to help amputees. This device is known as the LUKE arm. A man named Rob Spence in Canada replaced his missing eye with a prosthetic device that had a video camera installed. This video camera was able to transmit video wirelessly, but could only work for about half an hour. In 1998, a man named Kevin Warwick put a microchip into his own arm. This microchip allowed him to control heaters and computer remotely. Surgically installing anything into the human body has some risks, and if the device malfunctions it will have to be surgically removed. However, engineers and doctors are continuing their research to improve technology used in smart prosthetics. The branch of study dedicated to understanding how robots and organisms can interface and communicate with each other is called “cybernetics”.
