AI has largely existed in virtual spaces. Ace was built to change that—and today, that research was published in @nature.com. Michael Spranger, President of Sony AI, explains what it actually required.

Why can't you just program a robot to play table tennis? Peter Dürr and Peter Stone explain, and the answer gets to the heart of what makes physical AI hard.

What happens when a ball hits the net? In table tennis, net contact creates unpredictable trajectories. For Ace, Sony AI's physical AI research system, these rare events were one of the hardest real-world conditions to address.

How does Ace—Sony AI's robotic AI research system—plan a serve? Published in @nature.com, Ace is the first robot to beat a professional athlete in a physical sport. Before a serve, Ace predicts how spin will affect the ball's flight and bounce to guide real-time execution.

How does Ace read spin in real time? Published in @nature.com, Ace is the first robot to beat a professional athlete in a physical sport. Its Gaze Control System tracks spin during fast rallies, helping it interpret the game as it unfolds.

The first robot ping-pong prototype appeared in 1983. For more than forty years, no machine could see, decide, and act within the window required to compete with elite players. That changes today.

Every autonomous robot depends on three functions: sensing, deciding, and acting. The challenge isn't building each one. It's integrating all three fast enough to be useful.

For 40+ years, building a robot that could rally with an elite human table tennis player at full speed was an unsolved problem. Sony AI's Ace research project set out to change that—and the results are now accepted for publication in @nature.com and featured on the cover.
