Acquiring a shared environment representation
(Georgia Institute of TechnologyAssociation of Computing Machinery, 2006)Interacting with a domestic service robot implies the existence for a joint environment model for a user and a robot. We present a pilot study that investigates, how humans present a familiar environment to a mobile robot. ... -
Exploiting Distinguishable Image Features in Robotic Mapping and Localization
(Georgia Institute of TechnologySpringer Verlag, 2006-03)Simultaneous localization and mapping (SLAM) is an important research area in robotics. Lately, systems that use a single bearing-only sensors have received significant attention and the use of visual sensors have been ... -
Clarification dialogues in human-augmented mapping
(Georgia Institute of TechnologyAssociation for Computing Machinery, 2006-03)An approach to dialogue based interaction for resolution of ambiguities encountered as part of Human-Augmented Mapping (HAM) is presented. The paper focuses on issues related to spatial organisation and localisation. The ... -

Pay Attention When Selecting Features
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2006-08)In this paper, we propose a new, hierarchical approach to landmark selection for simultaneous robot localization and mapping based on visual sensors: a biologically motivated attention system finds salient regions of ... -
What's in the gap? Interaction transitions that make HRI work
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2006-09)This paper presents an in-depth analysis from a Human Robot Interaction (URI) study on spatial positioning and interaction episode transitions. Subjects showed a living room to a robot to teach it new places and objects. ... -
Evaluation of Passing Distance for Social Robots
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2006-09)Casual encounters with mobile robots for nonexperts can be a challenge due to lack of an interaction model. The present work is based on the rules from proxemics which are used to design a passing strategy. In narrow ... -
A Discriminative Approach to Robust Visual Place Recognition
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 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 ... -
Bringing Together Human and Robotic Environment Representations – A Pilot Study
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2006-10)Human interaction with a service robot requires a shared representation of the environment for spoken dialogue and task specification where names used for particular locations are depending on personal preferences. A ... -
SLAM using Visual Scan-Matching with Distinguishable 3D Points
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2006-10)Scan-matching based on data from a laser scanner is frequently used for mapping and localization. This paper presents an scan-matching approach based instead on visual information from a stereo system. The Scale Invariant ... -
Design of an Office-Guide Robot for Social Interaction Studies
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2006-10)In this paper, the design of an office-guide robot for social interaction studies is presented. We are interested in studying the impact of passage behaviours in casual encounters. While the system offers assistance in ... -
Measurement Errors in Visual Servoing
(Georgia Institute of TechnologyElsevier, 2006-10)This paper addresses the issue of measurement errors in visual servoing. The error characteristics of the vision based state estimation and the associated uncertainty of the control are investigated. The major contribution ... -
Topological Modelling for Human Augmented Mapping
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2006-10)Service robots designed for domestic settings need to navigate in an environment that they have to share with their users. Thus, they have to be able to report their current state and whereabouts in a way that is ... -
Design of a Control Strategy for Teleoperation of a Platform with Significant Dynamics
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2006-10)A teleoperation system for controlling a robot with fast dynamics over the Internet has been constructed. It employs a predictive control structure with an accurate dynamic model of the robot to overcome problems caused ... -
Attentional Landmark Selection for Visual SLAM
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2006-10)In this paper, we introduce a new method to automatically detect useful landmarks for visual SLAM. A biologically motivated attention system detects regions of interest which “pop-out” automatically due to strong contrasts ... -
Darwinian embodied evolution of the learning ability for survival
(Georgia Institute of TechnologySageInternational Society for Adaptive Behavior, 2007)In this article we propose a framework for performing embodied evolution with a limited number of robots, by utilizing time-sharing in subpopulations of virtual agents hosted in each robot. Within this framework, we explore ... -
