For the first time, an AI-powered machine has bested elite-level athletes at a physical sport. 'Ace' is a table tennis-playing robot. It can calculate the position of a ball in space, measure its spin while it's flying over the table at 30mph and react in a tenth of the time a human player would need. Designing and training this system was no easy task...
