    • Modeling & Characterizing Stochastic Actuator Arrays 

      MacNair, David L.; Ueda, Jun (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009-10)
      If the modal response for a single degree of freedom flexible system is known, a command generation architecture can be determined which schedules on/off actuator effort such that the resulting motion will have zero ...
    • Motor Task Planning for Neuromuscular Function Tests using an Individual Muscle Control Technique 

      Ueda, Jun; Hyderabadwala, Moiz; Krishnamoorthy, Vijaya; Shinohara, Minoru (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009-06)
      A functionality test at the level of individual muscles may be effective for neuromuscular function tests. This paper proposes a novel computational method for neuromuscular function test planning using an individual muscle ...
    • Piezoelectric Self-Sensing Technique for Tweezer Style End-effector 

      McPherson, Timothy; Ueda, Jun (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2011-12)
      This paper presents the application of a piezoelectric self-sensing technique based on discharged current to robotic tweezers incorporating a rhombus strain amplification mechanism driven by serially connected piezoelectric ...
    • Piezoelectric Tweezer-type End-effector with Force- and Displacement-Sensing Capability 

      Kurita, Yuichi; Sugihara, Fuyuki; Ueda, Jun; Ogasawara, Tsukasa (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2011-06)
      This paper presents the design and development of robotic tweezers with a force- and displacement-sensing capability driven by piezoelectric stack actuators. In order to satisfy sufficient stroke and tip-force for future ...
    • Pinpointed Muscle Force Control Taking Into Account the Control DOF of Power-assisting Device 

      Ding, Ming; Kurita, Yuichi; Ueda, Jun; Ogasawara, Tsukasa (Georgia Institute of TechnologyAmerican Society of Mechanical Engineers, 2010-09)
    • Wearable Sensorimotor Enhancer for a Fingertip based on Stochastic Resonance 

      Kurita, Yuichi; Shinohara, Minoru; Ueda, Jun (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2011-05)
      This paper reports the initial experimental results of a wearable sensorimotor enhancer for a fingertip. A shorttime exposure of tactile receptors to sub-sensory white-noise vibration is known to improve the tactile ...
