    A novel approach of constructing a robust variable-speed drive system using an induction motor supplied from a voltage-source-type PWM inverter is discussed. The inverter is controlled so as to generate the fabricated terminal voltages based on the voltage-decoupled transvector control theory where neither a current feedback loop nor a current limiter circuit is required. Although the hardware for... View full abstract»

    The quadruped walking robot called TURTLE-1 is described. A novel link mechanism named ASTBALLEM is used to construct highly rigid and easily controllable legs. Each leg has two degrees of freedom and is driven by two DC servomotors. The motion of the legs is controlled by a microcomputer, and various gaits are generated so that the robot walks not only statically but also quasidynamically. When t... View full abstract»

    Methods are described for vision-guided robotic control of fabric motion for performing simulated joining operations for apparel manufacturing. The determination of robot motion paths is based on visual information defining the position of the fabric edges in world coordinates. The usefulness of the shape analysis and motion control algorithms is demonstrated by experimentation with an integrated ... View full abstract»

    An automated deburring procedure using a robot manipulator is considered for the removal of burrs in the presence of robot oscillations and bounded uncertainties in the tool holder. Electronic compliancy (impedance control) is proposed as an adaptive mechanism to satisfy the requirements of this application. The development and implementation of the impedance control methodology on an active end-e... View full abstract»

    A pilot study that compares vision systems that might be used to control a teleoperated land vehicle is described. The study compares three forward-looking vision systems, both for actual remote driving and for noninteractive video simulation. Remote driving has the advantage of realism but is subject to variability in driving strategies and can be hazardous to equipment. Video simulation provides... View full abstract»

    The application of a procedure for classifying tissue types from unlabeled acoustic measurements using unsupervised analysis is reviewed and evaluated. Unsupervised learning techniques are applied to the problems of detecting tumors within an organ and of discriminating between tissue types of two neighboring organs such as the liver and the kidney.<> View full abstract»
