From a four-legged robot goalkeeper to a Google AI ping-pong champion, a number of robots are already taking the world of sports by storm. Now, it seems that droids are preparing to take on the pros at boxing. An alarming video has revealed a huge humanoid robot boxing with a human - and throwing some impressive punches. The robot, dubbed Nadia, is described as a'next generation humanoid for the next generation of robotics.' The footage has raised concerns from many viewers, with one commenting: 'Wait till Mr robot get the mind of its own and punches you out for real.' Nadia is the brainchild of researchers at IHMC Robotics and Boardwalk Robotics.
