Sony AI announced on April 22 that its research on the autonomous robot "Ace" has been published as a cover paper in Nature. Ace is an autonomous system that can compete against elite and professional human players in real-world table tennis competitions, and Sony AI sees this as a major milestone in real-world AI and robotics. The significance of this study lies in the fact that AI has shown high performance not only in digital spaces such as chess and Go, but also in rapidly changing physical spaces. Table tennis is a very difficult competition for robots because it requires the speed of the ball, its rotation, trajectory changes, and its quick response to the opponent. Ace demonstrated human-level reaction speed and judgment under these conditions. The Ace is equipped with nine APS cameras and three line-of-sight control systems that provide real-time visibility into the ball's three-dimensional position and rotation. In addition, model-free reinforcement learning controls and high-precision hardware allow you to quickly respond to unpredictable plays. In its ratings at the time of publication in Nature, Ace faced five elite players and two pros, recording three wins in five matches against elite players. He showed a return rate of over 75% against strong spinning balls up to 450 radians per second, and scored 16 points from his serve against elite players. It also supports irregular balls that hit the net, showing high versatility in actual combat. Sony AI explains that this achievement extends beyond table tennis and shows its potential for applications in manufacturing, logistics, medical assistance, and safety-critical settings. In additional matches after the submission of the paper, Ace has won against new professional players, and his performance continues to improve. This is positive news that shows that the era of AI perceiving, judging, and acting in the real world is even closer.
