Google’s DeepMind can management a robotic arm to beat mere mortals at table tennis, a brand new examine reviews. However Fan Zhendong, the 2024 gold medalist for particular person and group males’s table tennis, can relaxation simple: The artificial intelligence (AI)-powered robotic may solely beat mediocre gamers, and solely a few of the time, based on the examine, which was printed Aug. 7 to the preprint database arXiv and has not been peer-reviewed.
Robots can now prepare dinner, clear and carry out acrobatics, however they wrestle to shortly reply to real-world environmental data.
“Attaining human-level efficiency by way of accuracy, velocity and generality nonetheless stays a grand problem in lots of domains,” the researchers wrote within the examine.

To beat this limitation, the researchers mixed an industrial robot arm with a personalized model of DeepMind’s ultrapowerful studying algorithm. DeepMind makes use of neural networks, a layered structure that mimics how data is processed within the human mind, to step by step study new data. To this point, it has crushed the world’s best Go player, predicted the structure of every protein in the body, cracked decades-old mathematics problems and extra.
The system was skilled to grasp particular facets of the sport — for example, studying the foundations, creating high spin, delivering forehand serves or utilizing backhand concentrating on — coaching on real-world and simulated knowledge in refined algorithms. Because the AI realized, the researchers additionally collected knowledge on its strengths, weaknesses and limitations. Then, they fed this data again to the AI program, thus giving DeepMind’s unnamed agent a practical impression of its talents. The system then picked which expertise or methods to make use of within the second, considering its opponent’s strengths and weaknesses, identical to a human table-tennis participant would possibly.
Then, they pitted their AI-controlled robotic towards 29 humans. DeepMind’s robotic arm beat the entire freshmen and about 55% of the intermediate gamers, nevertheless it acquired trounced by superior gamers. In a global score system, it will be a strong novice participant.
DeepMind’s robotic arm did have some systematic weaknesses, nonetheless. For instance, it struggled with excessive balls and, like many people, discovered backhand photographs more difficult than forehand ones.
Many of the human gamers appeared to love enjoying towards the system. “Throughout all talent teams and win charges, gamers agreed that enjoying with the robotic was ‘enjoyable’ and ‘partaking,’ the researchers wrote within the examine.
The brand new strategy could possibly be helpful for a variety of purposes that decision for fast responses in dynamic bodily environments, the researchers mentioned.
