    • Tables, Counters, and Shelves: Semantic Mapping of Surfaces in 3D 

      Trevor, Alexander J. B.; Rogers, John G.; Nieto-Granda, Carlos; Christensen, Henrik I. (Georgia Institute of Technology, 2010-10)
      Semantic mapping aims to create maps that include meaningful features, both to robots and humans. We present an extension to our feature based mapping technique that includes information about the locations of horizontal ...
    • Teleoperation for a Ballcatching Task with Significant Dynamics 

      Smith, Christian; Bratt, Mattias; Christensen, Henrik I. (Georgia Institute of TechnologyElsevier, 2008-05)
      In this paper we present ongoing work on how to incorporate human motion models into the design of a high performance teleoperation platform. A short description of human motion models used for ballcatching is followed ...
    • Topological Modelling for Human Augmented Mapping 

      Topp, Elin A.; Christensen, Henrik I. (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 ...
    • Towards robust place recognition for robot localization 

      Ullah, M. M.; Pronobis, A.; Caputo, B.; Luo, J.; Jensfelt, Patric; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 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 ...
    • Trust Modeling in Multi-Robot Patrolling 

      Pippin, Charles; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2014-06)
      On typical multi-robot teams, there is an implicit assumption that robots can be trusted to effectively perform assigned tasks. The multi-robot patrolling task is an example of a domain that is particularly sensitive to ...
    • Using COTS to Construct a High Performance Robot Arm 

      Smith, Christian; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2007-04)
      In this paper we present a design study and technical specifications of a high performance robotic manipulator to be used for ball catching experiments using commercial off-the-shelf (COTS) components. Early evaluation ...
    • Visual Place Categorization: Problem, Dataset, and Algorithm 

      Wu, Jianxin; Rehg, James M.; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 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. ...
    • What's in the gap? Interaction transitions that make HRI work 

      Hüttenrauch, Helge; Eklundh, Kerstin Severinson; Green, Anders; Topp, Elin A.; Christensen, Henrik I. (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. ...
    • Wii-mote robot control using human motion models 

      Smith, Christian; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009-10)
      As mass-market video game controllers have become more advanced, there has been a recent increase in interest for using these as intuitive and inexpensive control devices. In this paper we examine position control for ...
