Learning Personalized Safety Interventions for Haptic Human-Robot Shared Control
Dawei Zhang, Roberto Tron
Haptic feedback provides an implicit channel for communicating safety intentions during human-robot shared control. Existing haptic guidance systems typically employ predefined int…
Embedding Semantic Risk into Distance Fields and CBFs for Online Monocular Safe Control
Dawei Zhang, Nuo Chen, Shuo Liu +2
We propose an online monocular perception-to-control framework that embeds semantic risk into the distance field used by Control Barrier Function (CBF)-based safe navigation and te…
BoxMap: Efficient Structural Mapping and Navigation
Zili Wang, Christopher Allum, Sean B. Andersson +1
While humans can successfully navigate using abstractions, ignoring details that are irrelevant to the task at hand, most existing robotic applications require the maintenance of a…
Safe and Stable Teleoperation of Quadrotor UAVs under Haptic Shared Autonomy
Dawei Zhang, Roberto Tron
We present a novel approach that aims to address both safety and stability of a haptic teleoperation system within a framework of Haptic Shared Autonomy (HSA). We use Control Barri…
