[2408.03906] Achieving Human Level Competitive Robot Table Tennis
https://arxiv.org/abs/2408.03906
Meet our AI-powered robot that¡Çs ready to play table tennis. ????????
It¡Çs the first agent to achieve amateur human level performance in this sport. Here¡Çs how it works. ???? pic.twitter.com/AxwbRQwYiB— Google DeepMind (@GoogleDeepMind) August 8, 2024

Robotic table tennis has served as a benchmark for this type of research since the 1980s.
The robot has to be good at low level skills, such as returning the ball, as well as high level skills, like strategizing and long-term planning to achieve a goal. pic.twitter.com/IX7VuDyC4J— Google DeepMind (@GoogleDeepMind) August 8, 2024

To train the robot, we gathered a dataset of initial table tennis ball states - which included information about position, speed, and spin.
The system practiced using this library and learned different skills, like forehand topspin, backhand targeting, and returning serves. pic.twitter.com/zqGg1Fxf7F— Google DeepMind (@GoogleDeepMind) August 8, 2024

Our robot first trains in a simulated environment, which can model the physics of table tennis matches accurately.
Once deployed to the real world, it collects data on its performance against humans to refine its skills back in simulation - creating a continuous feedback loop. pic.twitter.com/Yyz4KA09yp— Google DeepMind (@GoogleDeepMind) August 8, 2024

We also designed the system to adapt to various opponents by tracking their behaviors and playing style - such as which side of the table they tend to return the ball to.
This allows it to try different skills, monitor its success rate and adjust its strategy on the fly. pic.twitter.com/8TExTdKZ0v— Google DeepMind (@GoogleDeepMind) August 8, 2024

It went up against 29 unseen human opponents across 4️⃣ different skill levels during our research - from beginner to advanced.
Overall, the robot scored in the middle of participants, implying that the system can operate like an intermediate amateur. pic.twitter.com/k4ngwznowG— Google DeepMind (@GoogleDeepMind) August 8, 2024

In short, no. There are physical as well as skill limitations, including: reaction speed, camera sensing capabilities, spin handling and the paddle rubber, which is hard to accurately model in simulation. pic.twitter.com/oBLXiep1cu— Google DeepMind (@GoogleDeepMind) August 8, 2024
