Mitigating Over-Assistance in Teleoperated Mobile Robots via Human-Centered Shared Autonomy: Leveraging Suboptimal Rationality Insights

RA-L 2025

In this letter, we introduce a human-centered shared autonomy approach to address over-assistance in remote robot operation, aimed at reducing control conflicts and enhancing user experience. We model the human-robot team as a partially observable Markov decision process (POMDP) that incorporates un

RA-RRTV*: Risk-Averse RRT* With Local Vine Expansion for Path Planning in Narrow Passages Under Localization Uncertainty

RA-L 2025

Recent advances in sampling-based algorithms have enhanced the ability of mobile robots to navigate safely in environments with localization uncertainty. However, navigating narrow passages remains a significant challenge due to the heightened risks posed by uncertainty. In this letter, we present a

RT-RRT: Reverse Tree Guided Real-Time Path Planning/Replanning in Unpredictable Dynamic Environments

IROS 2024poster

Path planning in unpredictable dynamic environments remains a challenging problem due to the unpredictable appearance, disappearance, and movement of dynamic obstacles during navigation. To address this problem, we propose a reverse tree guided rapid exploration random tree (RTRRT) algorithm that ca…

Reconciling Conflicting Intents: Bidirectional Trust-Based Variable Autonomy for Mobile Robots

RA-L 2024

In the realm of semi-autonomous mobile robots designed for remote operation with humans, current variable autonomy approaches struggle to reconcile conflicting intents while ensuring compliance, autonomy, and safety. To address this challenge, we propose a bidirectional trust-based variable autonomy

Modeling and Design of a Pigeon-Inspired Robot With Passively Bending Wings

RA-L 2023

Most traditional ornithopters are equipped with active deformation wings for flight control. However, this inevitably results in redundant actuators and a complex mechanical structure, that reduce flight efficiency. According to the flight data of pigeons ( <italic xmlns:mml="http://www.w3.org/1998/
