To make learning in few trials possible the method is embedded into our robot system. In this way we can use a one-step environment. ...
In typical robotic applications, however, the number of feasible attempts is very limited. In this paper we present a sample-efficient RL algorithm applied to the example of a table tennis robot. ...
The learning process is integrated into an existing robot system using a KUKA Agilus KR 6 R900 robot arm. The robot could learn an accurate return in under 200 balls. ...
