    • An Ethological and Emotional Basis for Human-Robot Interaction 

      Arkin, Ronald C.; Fujita, Masahiro; Hasegawa, Rika; Takagi, Tsuyoshi (Georgia Institute of Technology, 2002)
      This paper presents the role of ethological and emotional models as the basis for an architecture in support of entertainment robotic systems. Specific examples for Sony’s AIBO are presented as well as extensions related ...
    • Ethological Modeling and Architecture for an Entertainment Robot 

      Arkin, Ronald C.; Fujita, Masahiro; Hasegawa, Rika; Takagi, Tsuyoshi (Georgia Institute of Technology, 2001)
      This paper presents a novel method for creating high-fidelity models of animal behavior for use in robotic systems based on a behavioral systems approach, and describes in particular how an ethological model of a domestic ...
    • European Robot Symposium - 2006 

      Christensen, Henrik I.; Georgia Institute of Technology. College of Computing; Georgia Institute of Technology. Center for Robotics and Intelligent Machines (Georgia Institute of TechnologySpringer Verlag, 2006-03)
    • Evaluating the Usability of Robot Programming Toolsets 

      Arkin, Ronald C.; MacKenzie, Douglas Christopher (Georgia Institute of Technology, 1997-10-14)
      The days of specifying missions for mobile robots using traditional programming languages such as C++ and LISP are coming to an end. The need to support operators lacking programming skills coupled with the increasing ...
    • Evaluation of Passing Distance for Social Robots 

      Pacchierotti, Elena; Christensen, Henrik I.; Jensfelt, Patric (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 ...
    • Evolutionary Development of Hierarchical Learning Structures 

      Elfwing, Stefan; Uchibe, Eiji; Doya, Kenji; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2007-04)
      Hierarchical reinforcement learning (RL) algorithms can learn a policy faster than standard RL algorithms. However, the applicability of hierarchical RL algorithms is limited by the fact that the task decomposition has ...
