Center node: "blackbox end to end verification of ground robot safety and liveness"
  Abstract: We formally prove end-to-end correctness of a ground robot implemented in a simulator. We use an untrusted controller supervised by a verified sandbox. Contributions include: (i) A model of the robot in differential dynamic logic, which specifies assumptions on the controller and robot kinematics, (ii) Formal proofs of safety and liveness for a waypoint-following problem with speed limits, (iii) An automatically synthesized sandbox, which is automatically proven to enforce model compliance at runtime, and (iv) Controllers, planners, and environments for the simulations. #R##N#The verified sandbox is used to safeguard (unverified) controllers in a realistic simulated environment. Experimental evaluation of the resulting sandboxed implementation confirms safety and high model-compliance, with an inherent trade-off between compliance and performance. The verified sandbox thus serves as a valuable bidirectional link between formal methods and implementation, automating both enforcement of safety and model validation simultaneously.
