• Bio-inspired Assistive Robotics: Service Dogs as a Model for Human-Robot Interaction and Mobile Manipulation 

      Nguyen, Hai; Kemp, Charles C. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2008-10)
      Service dogs have successfully provided assistance to thousands of motor-impaired people worldwide. As a step towards the creation of robots that provide comparable assistance, we present a biologically inspired robot ...
    • Hand It Over or Set It Down: A User Study of Object Delivery with an Assistive Mobile Manipulator 

      Choi, Young Sang; Chen, Tiffany L.; Jain, Advait; Anderson, Cressel D.; Glass, Jonathan D.; Kemp, Charles C. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009)
      Delivering an object to a user would be a generally useful capability for service robots. Within this paper, we look at this capability in the context of assistive object retrieval for motor-impaired users. We first describe ...
    • Haptic Classification and Recognition of Objects Using a Tactile Sensing Forearm 

      Bhattacharjee, Tapomayukh; Rehg, James M.; Kemp, Charles C. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2012-10)
      In this paper, we demonstrate data-driven inference of mechanical properties of objects using a tactile sensor array (skin) covering a robot's forearm. We focus on the mobility (sliding vs. fixed), compliance (soft vs. ...
    • Perceiving Clutter and Surfaces for Object Placement in Indoor Environments 

      Schuster, Martin J.; Okerman, Jason; Nguyen, Hai; Rehg, James M.; Kemp, Charles C. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2010-12)
      Handheld manipulable objects can often be found on flat surfaces within human environments. Researchers have previously demonstrated that perceptually segmenting a flat surface from the objects resting on it can enable ...
    • RF vision: RFID receive signal strength indicator (RSSI) images for sensor fusion and mobile manipulation 

      Deyle, Travis; Nguyen, Hai; Reynolds, Matt S.; Kemp, Charles C. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009-10)
      In this work we present a set of integrated methods that enable an RFID-enabled mobile manipulator to approach and grasp an object to which a self-adhesive passive (battery-free) UHF RFID tag has been affixed. Our primary ...
    • Visual Odometry and Control for an Omnidirectional Mobile Robot with a Downward-Facing Camera 

      Killpack, Marc D.; Deyle, Travis; Anderson, Cressel D.; Kemp, Charles C. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2010-10)
      An omnidirectional Mecanum base allows for more flexible mobile manipulation. However, slipping of the Mecanum wheels results in poor dead-reckoning estimates from wheel encoders, limiting the accuracy and overall utility ...
