      Choi, Young Sang; Deyle, Travis; Chen, Tiffany L.; Glass, Jonathan D.; Kemp, Charles C. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009-06)
      Studies have consistently shown that object retrieval would be a valuable task for assistive robots to perform, yet detailed information about the needs of patients with respect to this task has been lacking. In this paper, ...
    • A List of Household Objects for Robotic Retrieval Prioritized by People with ALS (Version 092008) 

      Choi, Young Sang; Deyle, Travis; Kemp, Charles C. (Georgia Institute of TechnologyarXiv.org, 2008-09)
      This technical report is designed to serve as a citable reference for the original prioritized object list that the Healthcare Robotics Lab at Georgia Tech released on its website in September of 2008. It is also expected ...
    • Local Navigation Strategies for a Team of Robots 

      Arkin, Ronald C.; Sgorbissa, Antonio (Georgia Institute of Technology, 2001)
      Whenever a mobile robot has to deal with an environment that is totally or partially unknown or dynamically changing, local navigation strategies are very important for the robot to successfully achieve its goals. ...
    • Long-Term Study of a Portable Field Robot in Urban Terrain 

      Lundberg, Carl; Christensen, Henrik I.; Reinhold, Roger (Georgia Institute of TechnologyJohn Wiley & Sons, 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 ...
    • Long-term study of portable field robots in urban terrain 

      Lundberg, Carl; Christensen, Henrik; Reinhold, Roger (Georgia Institute of TechnologyAssociation for Computing Machinery, 2006-08)
    • Longitudinal Motion Planning for Slung-Loads Using Simplified Models and Rapidly-Exploring Random Trees 

      Johnson, Eric N.; Mooney, John G. (Georgia Institute of Technology, 2015-01)
      A randomized motion-planning approach to providing guidance for helicopters with under-slung loads is presented. Rapidly-exploring Random Trees are adapted to plan trajectories for simplified helicopter-load models. Four ...
    • Loopy SAM 

      Ranganathan, Ananth; Kaess, Michael; Dellaert, Frank (Georgia Institute of TechnologyIJCAI, 2007-01)
      Smoothing approaches to the Simultaneous Localization and Mapping (SLAM) problem in robotics are superior to the more common filtering approaches in being exact, better equipped to deal with non-linearities, and computing ...
    • Low cost automation with lighter, versatile machines 

      Book, Wayne John (Georgia Institute of TechnologyPublished for the International Federation of Automatic Control by Pergamon Press, 1986-11)
