Safe autonomy with imperfect information

Abstract

Modern autonomous systems, like self-driving cars, unmanned aerial vehicles, or robots, are equipped with advanced sensing, learning, and perception modules. On one hand these modules render the overall system more informed, possibly providing predictions into the future. On the other hand, they can be unreliable, as in the case of vision-based perception algorithms unexpectedly failing to detect the obstacles. In this talk, I will discuss some of our recent work on problems that deal with synthesizing controllers to ensure safety and invariance in the presence of information imperfections or predictions. I will show problem instances in these different information regimes when control synthesis can be achieved in a scalable way. I will also discuss how these ideas can be extended to develop algorithms for corner case generation for testing and falsification purposes.
