    • 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)
      We demonstrate the automatic transfer of an assembly task from human to robot. This work extends efforts showing the utility of linguistic models in verifiable robot control policies by now performing real visual analysis ...
