• 1-DOF Dynamic Pitching Robot that Independently Controls Velocity, Angular Velocity, and Direction of a Ball 

      Mori, Wataru; Ueda, Jun; Ogasawara, Tsukasa (Georgia Institute of TechnologyBrill Academic Publishers, 2010)
      This paper demonstrates that a 1-DOF planar ball-throwing robot has the capability of controlling three kinematic variables of a ball independently: translational velocity, angular velocity, and direction. The throwingmotion ...
    • Individual Muscle Control using an Exoskeleton Robot for Muscle Function Testing 

      Ueda, Jun; Ming, Ding; Krishnamoorthy, Vijaya; Shinohara, Minoru; Ogasawara, Tsukasa (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2010-08)
      Healthy individuals modulate muscle activation patterns according to their intended movement and external environment. Persons with neurological disorders (e.g., stroke and spinal cord injury), however, have problems in ...
    • 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 ...
    • 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 ...
