    Individual Muscle Control using an Exoskeleton Robot for Muscle Function Testing 

    Ueda, Jun; Ming, Ding; Krishnamoorthy, Vijaya; Shinohara, Minoru; Ogasawara, Tsukasa (Georgia Institute of Technology, 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 ...

    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 Technology, 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 ...

    Experimental Verification of Discrete Switching Vibration Suppression 

    Schultz, Joshua; Ueda, Jun (Georgia Institute of Technology, 2011-01-20)
    Control system design for flexible robotic systems requires special care with regard to the control system design to prevent oscillation in the system's resonant modes. If the resonant frequencies of such a system are ...
