Risk-Averse Planning via CVaR Barrier Functions: Application to Bipedal Robot Locomotion

Understand

Enforcing safety in the presence of stochastic uncertainty is a challenging problem.

• Traditionally, researchers have proposed safety in the statistical mean as a safety measure in this case.
• However, ensuring safety in the statistical mean is only reasonable if system's safe behavior in the large number of runs is of interest, which precludes the use of mean safety in practical scenarios.
• In this paper, we propose a risk sensitive notion of safety called conditional-value-at-risk (CVaR) safety, which is concerned with safe performance in the worst case realizations.
