• Adaptive CPG based coordinated control of healthy and robotics lower limb movement 

      Ryu, Jae-Kwan; Chong, Nak Young; You, Bum Jae; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009-09)
      This paper proposes an adaptive CPG based controller for a lower limb prosthesis consisting of online trajectory generation and interlimb coordination. The adaptive CPG can produce multidimensional rhythmic patterns ...
    • Adaptive triangular mesh generation of self-configuring robot swarms 

      Lee, Geunho; Chong, Nak Young; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009-05)
      We address the problem of dispersing a large number of autonomous mobile robots toward building wireless ad hoc sensor networks performing environmental monitoring and control. For the purpose, we propose the adaptive ...
    • A Mobile Sensor Network Forming Concentric Circles Through Local Interaction and Consensus Building 

      Lee, Geunho; Yoon, Seokhoon; Chong, Nak Young; Christensen, Henrik I. (Georgia Institute of TechnologyFuji Technology Press Ltd., 2009)
      We address the problem of a swarm of autonomous mobile robotic sensors generating geometric shapes to build wireless ad hoc surveillance sensor networks. Robot swarms with limited observation are required to form ...
