How Did Ace Defeat Human Players? Analysis of Three Technological Breakthroughs

Ace’s success is not the victory of a single technology but the systematic integration of three core innovations: event sensors, model-free reinforcement learning, and high-speed hardware. The collaboration of these three technologies enables the robot to perceive in real time, make quick decisions, and execute precisely.

Event Sensors: Tracking Only Key Changes, Efficiency Boosted a Hundredfold

Traditional cameras capture dozens of full frames per second, but Ace’s event sensors record only dynamic changes in the scene—such as ball speed, spin, and landing point. This “focus on essentials” strategy drastically reduces data processing, allowing the robot to concentrate on tracking the ball’s trajectory. The Sony AI team states that this technology has a latency of only about 20 milliseconds, far below the 230-millisecond reaction time of human athletes.
