Sony engineers have developed a robot named Ace that can compete with elite human players in table tennis, beating 'elite' amateurs three times in five matches. The robot combines high-speed sensing, AI decision-making, and robotic control to compete in real-world conditions. This breakthrough represents a significant step towards creating robots with broader applications in fast, precise, and real-time human interactions. Ace's design includes a perception system that can track the ball's spin, an AI 'brain' trained by deep reinforcement learning, an eight-jointed robotic arm that can make decisions in the moment. The team's performance exceeded that of previous table tennis robots, reaching a level that could compete with high-level human players.
