    A rule-based, digital, closed-loop controller that incorporates fuzzy logic has been designed and implemented for the control of power on the 5-MW Massachusetts Institute of Technology (MIT) Research Reactor under both steady-state and transient conditions. A comparison is made of the rule-based and analytic approaches. Differences in the division of labor between plant engineers and control speci... 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»

    Current research on a versatile mechanical hand for robotic arms is described. This mechanical hand is a self-contained, autonomous system capable of executing high-level commands from a supervisory computer. It consists of parallel fingers powered by a DC motor and controlled by a microcomputer embedded in the hand housing. Sensors are integrated in the hand for measuring grasp force of fingers a...

    The structural design of a system called ODYSSEUS is discussed. The system consists of a triangle base with three programmable wheels, a special digital compass based on the Grey code, a sonar system in a hexagonal configuration, a slope meter, and a microprocessor controller that selects information from the above components and determines the navigation paths. The system possesses learning capab... View full abstract»

    A procedure is described in which an infrared detector is used to control the quality of solder joints being formed on printed circuit boards and a laser is used to inspect the quality of each joint at the same time. This approach eliminates after-the-fact inspection while making available real-time data for process control of the soldering operation. Although the joints are formed one at a time, ...

  • Adaptive controller for a glass viscoelastic testing process

    Publication Year: 1988, Page(s):33 - 40
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (627 KB)

    An adaptive controller has been designed to control the force and pressure of glass pressing tests for viscoelastic properties. The dynamics of the testing process appear to be nonlinear with the characteristic parameters varying drastically from test to test due to changes of glass compositions and the various test conditions. To automate the testing process, a self-tuning controller is designed ... View full abstract»
