So say the researchers behind a bot that can match the most skilled human baseball player faced with a hurtling ball. The robotic catcher, developed by scientists at the University of Tokyo, Japan, can comfortably grab a ball careering through the air at 300 kilometres per hour, or 83 metres per second, its creators say. And, of course, the robot never gets tired...
