SaRA: A Tool for Safe Human-Robot Coexistence and Collaboration through Reachability Analysis

ICRA 2022poster

Current safety mechanisms implementing industry standards for human-robot coexistence separate humans and robots through caging. Other approaches allowing humans to enter the workspace of manipulators do not provide formal safety guarantees. Thus, this study aims to facilitate the widespread adoptio…

Online Verification of Impact-Force-Limiting Control for Physical Human-Robot Interaction

IROS 2021poster

Humans must remain unharmed during their interaction with robots. We present a new method guaranteeing impact force limits when humans and robots share a workspace. Formal guarantees are realized using an online verification method, which plans and verifies fail-safe maneuvers through predicting rea…

Provably safe motion of mobile robots in human environments

IROS 2017poster

Mobile robots operating in a shared environment with pedestrians are required to move provably safe to avoid harming pedestrians. Current approaches like safety fields use conservative obstacle models for guaranteeing safety, which leads to degraded performance in populated environments. In this pap…
