Scenario Execution

Scenario execution is a backend- and middleware-agnostic library written in Python based on the generic scenario description language OpenSCENARIO 2 and pytrees. It reads a scenario definition from a file and then executes it, reusing available checks and actions. It is easily extendable through a library mechanism. This separation of the scenario definition from implementation massively reduces the manual efforts of scenario creation.

To give an impression of the functionality of scenario execution, the following animation shows an example scenario with a turtlebot-like robot in simulation using Nav2 and ROS as middleware to navigate towards a specified navigation goal in a simulated warehouse environment. Once the robot reaches a reference position a box is spawned in front of the robot as an unmapped static obstacle that needs to be avoided. Upon arrival of the goal position, the scenario ends and the simulation gets cleaned up.
