Presents a procedure for constructing controllers that limit and route information flow in autonomous underwater vehicle (AUV) networks. Particular attention is paid to the objectives of maximizing throughput and bandwidth efficiency while minimizing power consumption. Both a finite and infinite time horizon problem are formulated and solved for unique, piecewise continuous optimal controllers. In the infinite time case, a receding horizon system is adopted and a stability result for it is presented.

A fully automatic adjustment system for mass production of the optical head for magnetooptical disk drives is described. The optical head is composed of millimeter scale optical components, such as laser diode, the collimator lens, the object lens, various prisms and various detectors. A series of algorithms composed of measurement, recognition, calculation of manipulation, execution of manipulation, verification and fixation ensures proper adjustment of the head. The key is to process the measured value, recognize the shape of the beam and the waveform, and determine the manipulation. With this system, the adjustment process is reduced to 6 minutes, as compared to 9 hours it takes an experience worker.

An object-oriented modular approach to the engineering of complex robotic systems emphasizes reliability, reusability, ease of development, and user and network interfaces. This modular approach integrates many architectural principles and computational techniques which support adaptive and learning capability at the local, modular level. The TETROBOT is a modular and reconfigurable robotic system which was developed to demonstrate the reliable performance in a wide variety of task domains through reconfiguration of the same fundamental hardware and software components. Such a modular approach emphasizes the synthesis and integration of engineering modules and takes advantage of object-oriented engineering principles to design for a family of tasks. This paper provides an overview of the TETROBOT modular system and describes three modular systems in other applications domains.

This paper proposes a new method of estimating the position and heading angle of a mobile robot moving on a flat surface. The proposed localization method utilizes two passive beacons and a single rotating ultrasonic sensor. The passive beacons consist of two cylinders with different diameters and reflect the ultrasonic pulses coming from the sonar sensor mounted on the mobile robot. The sonar sensor, again, mounted on a pan-tilt device then receives the reflected pulses while scanning over a wide area. The geometric parameter set of beacon is acquired from the sonar scan data obtained at a single mobile robot location using a new data processing algorithm. The presented algorithm is especially suitable for processing the sonar scan data obtained by ultrasonic sensor with wide beam spread. From this parameter set, the position and heading angle of the mobile robot is determined directly. The performance and validity of the proposed method are evaluated using two beacons and a single sonar sensor attached at the pan-tilt device mounted on a mobile robot, named LCAR, in our laboratory.

The central challenge of all manufacturing is making products to the right standards and delivering them at the right time. AT&T is upgrading its corporate and factory resource planning systems to improve control of day-to-day manufacturing. The Manufacturing Process Control System (MPCS), developed at the AT&T Engineering Research center (ERC), provides this support. MPCS connects the shop floor with production scheduling, accounting, product data archive, and engineering support systems.
