A computationally-lightweight algorithm called gatekeeper that ensures trajectories of a nonlinear system satisfy safety constraints despite sensing limitations and dynamic environments.
This paper presents a novel framework that integrates iterative model predictive control with discrete-time control barrier functions to generate collision-free trajectories for a robot navigating through tight and dynamically changing environments with both convex and nonconvex obstacles.
Tail risk measures, such as Value-at-Risk, Conditional Value-at-Risk, and Entropic Value-at-Risk, provide a systematic approach to quantifying and managing risk in robotic planning, control, and verification tasks. By focusing on rare but high-consequence events, these measures enable robots to balance performance and safety under uncertainty.
