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.

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 ...

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

Probabilistic terrain classification in unstructured environments

Robotics and Autonomous Systems, 2013
Autonomous navigation in unstructured environments is a complex task and an active area of research in mobile robotics. Unlike urban areas with lanes, road signs, and maps, the environment around our robot is unknown and unstructured. Such an environment requires careful examination as it is random, continuous, and the number of perceptions and ...

Fast mobile robots in unstructured environments

1993
This paper addresses the design, development and implementation of a fast mobile robot (> 5m/s) evolving in a crowded and ill-structured environment. It then considers the intelligent observation of ill-structured environments. The purpose of the experiments carried out is to emphasize some aspects of the motion planning problem, namely fast collision ...

Processing Image Data from Unstructured Environments

2023
Advanced mobility research centers capture large amounts of data from ground vehicle systems during development and experimentation in both manned and autonomous operations. This exponential growth of digital image data has given rise to the need of understanding the content of image datasets by clustering and classifying them without the use of manual

Simultaneous exploration and 3d mapping of unstructured environments

2004 IEEE International Conference on Systems, Man and Cybernetics (IEEE Cat. No.04CH37583), 2005
Mobile vehicles equipped with range sensing capabilities are well suited for exploring and mapping unknown environments. This paper describes such an exploration platform, based upon an all-terrain skid-steer vehicle and a forward-looking laser rangefinder.
