Man VS Machine: Who Plays Table Tennis Better? 🤖

TL;DR

A robot learns to play table tennis with great accuracy and speed after only 1.5 hours of training in a simulation environment.

Transcript

Dear Fellow Scholars, this is Two Minute Papers with Dr. Károly Zsolnai-Fehér. Today we are going to see if a robot can learn to play table tennis. Spoiler alert, the answer is yes, quite well in fact. That is surprising, but what is even more surprising is how quickly it learned to do that. Recently, we have seen a growing number of techniques whe... Read More
