'It totally blew my mind': Sony's Project Ace robot plays ping pong better than pros (www.techradar.com)

Sony AI has unveiled Project Ace, a groundbreaking autonomous robot that competes at a professional level in table tennis, recently achieving three wins against elite players in five matches. This milestone underscores the potential of AI to master highly interactive and unpredictable tasks, demonstrating advanced capabilities in high-speed perception and real-time responsiveness. Project Ace employs sophisticated techniques such as model-free reinforcement learning, which allows it to adapt dynamically to the varying play styles of human competitors, making it exceptionally agile on the court. Equipped with a custom track system, 360-degree arm rotation, and a network of nine cameras for enhanced spatial awareness, Project Ace analyzes ball spin and trajectory with unprecedented accuracy. The innovative "privileged critic" mechanism used during its training enables the robot to compare predicted outcomes with real-time data, facilitating rapid adjustments during matches. This development not only pushes the boundaries of robotic competition but also opens doors for future applications where robots navigate complex, unpredictable environments, suggesting that advancements like Project Ace could redefine robot capabilities in various fields, including potential Olympic participation.
