Exploring Unstructured Environment with Frontier Trees

Journal of Intelligent & Robotic Systems, 2017
This paper presents the frontier tree exploration algorithm, a novel approach to autonomously explore unknown and unstructured areas. Focus of this work is the exploration of domestic environments with lots of arbitrary obstacles, for example furbished appartements.

Autonomous Driving in Unstructured Environments: How Far Have We Come?

arXiv.org
Research on autonomous driving in unstructured outdoor environments is less advanced than in structured urban settings due to challenges like environmental diversities and scene complexity.

Supervisory telerobotics testbed for unstructured environments

Journal of Robotic Systems, 1992
AbstractThis article describes a telerobotics testbed for performing tasks such as assembly and repair of spacecraft in unstructured environments. This fully operational multiarm system can operate in teleoperated or supervisory control modes, as well as mixed shared‐control modes, thus enabling operations in totally to partially unstructured ...

Adaptive Robot Traversability Estimation Based on Self-Supervised Online Continual Learning in Unstructured Environments

IEEE Robotics and Automation Letters
Traversability estimation is a core function for robot navigation in off-road unstructured environments and diverse research results have been published so far. One of the recent approaches is using the self-supervised learning (SSL) technique.

Efficient Coverage of Unstructured Environments

2018
In this paper, we present a novel solution to mobile robot coverage of unstructured environments. We apply boustrophedon-based planning and use a heuristic to make the minimum sum of altitudes (MSA) decomposition, which computes an optimal exact cellular decomposition, applicable to more complex environments.

Autonomous Navigation in Unstructured Environments

IFAC Proceedings Volumes, 2004
Abstract Some of the most challenging applications for robotics lie outdoors in harsh and unstructured environments. These include land applications such as mining, construction and agriculture, maritime applications such as search and rescue, sub-sea mining, and environment monitoring, and in air applications such as mineral exploration, meteorology

Stereo based navigation in unstructured environments

IMTC 2001. Proceedings of the 18th IEEE Instrumentation and Measurement Technology Conference. Rediscovering Measurement in the Age of Informatics (Cat. No.01CH 37188), 2002
In this paper a stereo vision method is described developed for autonomous vehicle navigation in unstructured terrain. The disparity between the stereo image sequences is calculated with subpixel accuracy. Robust distance values are obtained by adding a continuity criterion term in the evaluation criterion and by using confidence measures for the found

Foundation Models for Autonomous Robots in Unstructured Environments

arXiv.org
Automating activities through robots in unstructured environments, such as construction sites, has been a long-standing desire. However, the high degree of unpredictable events in these settings has resulted in far less adoption compared to more ...
