  • Synthesize the model of the environment using automata learning, e.g., L* algorithms.

    • Need a model of the environment that can be refined to match real or simulated environments. An interesting topic is to allow failure reproduction. If the hybrid automaton exhibits a failing execution, how do we instantiate a witness execution in the ROS program with the simulator.
