This paper investigates the resilient multi-robot efficient search problem (R-MuRES), which aims at coordinating multiple robots for the minimal time detection of a 'non-adversarial' moving target. R-MuRES faces challenges like robot malfunctions and withdrawals during task execution, leading to a v…
The development of unmanned aerial vehicles (UAVs) with extended maneuverability has unlocked new applications such as complex inspection tasks at height. In this work, we introduce the Dragonfly drone, a novel tilt-rotor body-morphing UAV, capable of altering its shape and orientation without compr
This paper studies the multi-robot reliable navigation problem in uncertain topological networks, which aims at maximizing the robot team's on-time arrival probabilities in the face of road network uncertainties. The uncertainty in these networks stems from the unknown edge traversability, which is
Multi-robot navigation in complex environments relies on inter-robot communication and mutual observation for situational awareness. This paper studies the multi-robot navigation problem in unknown environments with line-ofsight (LoS) connectivity constraints. While previous works are limited to kno
Autonomous exploration requires a robot to explore an unknown environment while constructing an accurate map using Simultaneous Localization and Mapping (SLAM) techniques. Without prior information, the exploration performance is usually conservative due to the limited planning horizon. This letter
This paper considers the multi-robot active graph exploration problem, where robots need to collaboratively cover a graph environment while maintaining reliable pose estimation in collaborative Simultaneous Localization and Mapping (SLAM). Considering both objectives presents challenges for multi-ro…
Unmanned aerial vehicles (UAVs) for contact-based tasks at height can greatly improve the safety of the human workers involved. However, performing contact-based tasks with typical under-actuated UAVs is non-trivial. Due to their coupled translational and rotational dynamics and their limited statio…
Recent advances in multi-agent reinforcement learning (MARL) have significantly enhanced cooperation capabilities within multi-robot teams. However, the application to heterogeneous teams poses the critical challenge of combinatorial generalization—adapting learned policies to teams with new composi
Predicting the future actions of multiple pedestrians is an essential feature for autonomous robots co-working in human crowded-environments. Estimating the unknown future path is a challenging problem due to the complex interactions occurring among pedestrians. Although recent developments in Graph
This letter investigates the multi-robot patrolling (MuRP) problem in a discrete environment with the objective of achieving uniform node coverage probability distribution by the robot team. Existing MuRP solutions for uniform node coverage either involve high computational complexity for the global
This letter presents a new range of multi-robot search for a non-adversarial moving target problems, namely multi-robot reliable search (MuRRS). The term ‘reliability’ in MuRRS is defined as the expectation of a predefined utility function over the probability density function (PDF) of the target’s
