Representation granularity enables time-efficient autonomous exploration in large, complex worlds

C Cao, H Zhu, Z Ren, H Choset, J Zhang - Science Robotics, 2023 - science.org
We propose a dual-resolution scheme to achieve time-efficient autonomous exploration with
one or many robots. The scheme maintains a high-resolution local map of the robot's …

Search and rescue with sparsely connected swarms

Ear-based exploration on hybrid metric/topological maps

Q Zhang, D Whitney, F Shkurti… - 2014 IEEE/RSJ …, 2014 - ieeexplore.ieee.org
In this paper we propose a hierarchy of techniques for performing loop closure in indoor
environments together with an exploration strategy designed to reduce uncertainty in the …

[HTML][HTML] Simultaneous localization and mapping in a multi-robot system in a dynamic environment with unknown initial correspondence

H Malakouti-Khah… - Frontiers in Robotics …, 2024 - frontiersin.org
A basic assumption in most approaches to simultaneous localization and mapping (SLAM)
is the static nature of the environment. In recent years, some research has been devoted to …

Fair subdivision of multi-robot tasks

JCG Higuera, G Dudek - 2013 IEEE international conference on …, 2013 - ieeexplore.ieee.org
We study the problem of distributing a single global task between a group of heterogeneous
robots. We view this problem as a fair division game. In this setting, every robot defines a …

GS Martins, D Portugal, RP Rocha - Robot Operating System (ROS) The …, 2021 - Springer
The exploration of unknown environments is a particularly and intuitively detachable
problem, allowing the division of robotic teams into smaller groups, or even into individuals …

Multi-robot symmetric rendezvous search on the line

D Ozsoyeller, P Tokekar - IEEE Robotics and Automation …, 2021 - ieeexplore.ieee.org
We study the Symmetric Rendezvous Search Problem for a multi-robot system. There are
robots arbitrarily located on a line. Their goal is to meet somewhere on the line as quickly as …
