Stochastic Models in Robotics
(Georgia Institute of Technology, 2017-04-20)
Many stochastic problems of interest in engineering and science involve
random, rigid-body motions. In this talk, a variety of stochastic
phenomena that evolve on the group of rigid-body motions will be
discussed together ...
Solving Coverage Problems with Embedded Graph Grammars
(Georgia Institute of Technology, 2007-04)
We show how Embedded Graph Grammars (EGGs) are used
to specify local interaction rules between mobile robots in a natural manner. This formalism allows us to treat local network topologies, geometric
transition conditions, ...
A Discriminative Approach to Robust Visual Place Recognition
(Georgia Institute of Technology, 2006-10)
An important competence for a mobile robot system
is the ability to localize and perform context interpretation.
This is required to perform basic navigation and to facilitate
local specific services. Usually localization ...
Visual Place Categorization: Problem, Dataset, and Algorithm
(Georgia Institute of Technology, 2009-10)
In this paper we describe the problem of Visual
Place Categorization (VPC) for mobile robotics, which
involves predicting the semantic category of a place from image
measurements acquired from an autonomous platform. ...
Global and Regional Path Planners for Integrated Planning and Navigation
(Georgia Institute of Technology, 2005-12)
This paper presents a hierarchical strategy for field mobile robots that incorporates path planning at different ranges. At the top layer is a global path planner that utilizes gross terrain characteristics, such as hills ...
Towards robust place recognition for robot localization
(Georgia Institute of Technology, 2008-05)
Localization and context interpretation are two
key competences for mobile robot systems. Visual place recognition,
as opposed to purely geometrical models, holds promise of
higher flexibility and association of semantics ...
Long-Term Study of a Portable Field Robot in Urban Terrain
(Georgia Institute of Technology, 2007-09)
The armed forces have a considerable amount of experience in using robots for bomb
removal and mine clearing. Emerging technology also enables the targeting of other applications.
To evaluate if real deployment of new ...
An intelligent terrain-based navigation system for planetary rovers
(Georgia Institute of Technology, 2001-12)
A fuzzy logic framework for onboard terrain analysis and guidance towards traversable regions. An onboard terrain-based navigation system for mobile robots operating on natural terrain is presented. This system utilizes a ...
Behavior-Based Robot Navigation on Challenging Terrain: A Fuzzy Logic Approach
(Georgia Institute of Technology, 2002-06)
This paper presents a new strategy for behavior-based navigation of field mobile robots on challenging terrain, using a fuzzy logic approach and a novel measure of terrain traversability. A key feature of the proposed ...
Persistent Formation Control for Multi-Robot Networks
(Georgia Institute of Technology, 2008-12)
This paper presents a method for controlling
formations of mobile robots. In particular, the problem of
maintaining so-called "persistent formations" while moving
the formation from one location to another is defined ...
