  As data science applications gain adoption across industries, the tooling
landscape matures to facilitate the life cycle of such applications and provide
solutions to the challenges involved to boost the productivity of the people
involved. Reinforcement learning with agents in a 3D world could still face
challenges: the knowledge required to use a simulation software as well as the
utilization of a standalone simulation software in unattended training
pipelines.
  In this paper we review tools and approaches to train reinforcement learning
agents for robots in 3D worlds with respect to the robot Robotino and argue
that the separation of the simulation environment for creators of virtual
worlds and the model development environment for data scientists is not a well
covered topic. Often both are the same and data scientists require knowledge of
the simulation software to work directly with their APIs. Moreover, sometimes
creators of virtual worlds and data scientists even work on the same files. We
want to contribute to that topic by describing an approach where data
scientists don't require knowledge about the simulation software. Our approach
uses the standalone simulation software Webots, the Robot Operating System to
communicate with simulated robots as well as the simulation software itself and
container technology to separate the simulation from the model development
environment. We put emphasize on the APIs the data scientists work with and the
use of a standalone simulation software in unattended training pipelines. We
show the parts that are specific to the Robotino and the robot task to learn.
