      Bettadapura, Vinay; Thomaz, Edison; Parnam, Aman; Abowd, Gregory D.; Essa, Irfan (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2015-01)
      The pervasiveness of mobile cameras has resulted in a dramatic increase in food photos, which are pictures re- flecting what people eat. In this paper, we study how tak- ing pictures of what we eat in restaurants ...
    • Leveraging distribution and heterogeneity in robot systems architecture 

      O'Hara, Keith Joseph (Georgia Institute of Technology, 2011-08-03)
      Like computer architects, robot designers must address multiple, possibly competing, requirements by balancing trade-offs in terms of processing, memory, communication, and energy to satisfy design objectives. However, ...
    • Life-long mapping of objects and places in domestic environments 

      Rogers, John Gilbert (Georgia Institute of Technology, 2013-01-10)
      In the future, robots will expand from industrial and research applications to the home. Domestic service robots will work in the home to perform useful tasks such as object retrieval, cleaning, organization, and security. ...
    • Lift-off dynamics in a simple jumping robot 

      Aguilar, Jeffrey; Lesov, Alex; Wiesenfeld, Kurt; Goldman, Daniel I. (Georgia Institute of TechnologyAmerican Physical Society, 2012-10-26)
      We study vertical jumping in a simple robot comprising an actuated mass-spring arrangement. The actuator frequency and phase are systematically varied to find optimal performance. Optimal jumps occur above and below (but ...

      Arkin, Ronald C.; Diaz, Jonathan (Georgia Institute of Technology, 2001)
      In this paper we investigate how a team of robotic agents can self-organize for the exploration of a building subject to the constraint of maintaining line-of-sight communications. Three different behavioral strategies ...
    • Linear 2D Localization and Mapping for Single and Multiple Robot Scenarios 

      Dellaert, Frank; Stroupe, Ashley W. (Georgia Institute of Technology, 2002)
      We show how to recover 2D structure and motion linearly in order to initialize Simultaneous Mapping and Localization (SLAM) for bearings-only measurements and planar motion. The method supplies a good initial estimate ...
    • A linear dynamic model for flexible robotic manipulators 

      Hastings, Gordon Greene; Book, Wayne John (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 1987-02)
      The design of lightweight links for robotic manipulators results in flexible links. Accurate control of lightweight manipulators during the large changes in configuration common to robotic tasks requires dynamic models ...
    • Linear-Time Estimation with Tree Assumed Density Filtering and Low-Rank Approximation 

      Ta, Duy-Nguyen; Dellaert, Frank (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2014-09)
      We present two fast and memory-efficient approximate estimation methods, targeting obstacle avoidance applications on small robot platforms. Our methods avoid a main bottleneck of traditional ...

      Dantam, Neil; Nieto-Granda, Carlos; Christensen, Henrik I.; Stilman, Mike (Georgia Institute of TechnologySpringer Verlag, 2012-06)
      This work combines semantic maps with hybrid control models, generating a direct link between action and environment models to produce a control policy for mobile manipulation in unstructured environments. First, we generate ...
    • Linguistic Control of Mobile Robots 

      Egerstedt, Magnus B. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2001-10)
      In this paper we study the interactions between symbolic computer programs and mechanical devises, e.g. mobile robots. We show that by using motion description languages for generating continuous motions from symbolic input ...
    • Linguistic Transfer of Human Assembly Tasks to Robots 

      Dantam, Neil; Essa, Irfan; Stilman, Mike (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2012-10)
