    One of the fundamental aspects of vision is three-dimensional geometry referring to the relationship between the scene which is depicted and the images which are projections of that scene. This paper presents computational theories which deal with geometrical aspects of interpreting images as a three-dimensional (3D) scene. The presentation covers three levels of descriptions: micro-surface level,... View full abstract»

    Automation requires workpieces to be well organized. Current machine feeding technology is dominated by the use of human labor, mechanical feeders, or orientation preservation. All these techniques have problems and limitations that make an alternate solution desirable. Three vision algorithms are presented which enable a computer-controlled robot to acquire a single piece from a bin containing ra... View full abstract»

    The industrial robot's principal advantage over traditional automation is programmability. Robots can perform arbitrary sequences of pre-stored motions or of motions computed as functions of sensory input. This paper reviews requirements for and developments in robot programming systems. The key requirements for robot programming systems examined in the paper are in the areas of sensing, world mod... View full abstract»

    This paper describes the architecture of a robot system designed both to work in an integrated manufacturing environment and to support continuing research in programmable automation. Major system components include a controller, robot and sensor hardware, operator's pendant, and system software. A new high-level interactive language, AML, allows the user to combine manipulation, sensing, computat... View full abstract»

    The analysis, design, and evaluation of robotic systems for manufacturing applications require understanding of sensing, representation, and manipulation as well as the integration and configuration of computer processors for control of the system. Robotic assembly presents particularly complex research issues due to the physical interactions among workpieces, precise positioning, and complex geom... View full abstract»

    The Stanford Cart was a remotely controlled TV-equipped mobile robot. A computer program was written which drove the Cart through cluttered spaces, gaining its knowledge of the world entirely from images broadcast by an on-board TV system. The CMU Rover is a more capable, and neatly operational, robot being built to develop and extend the Stanford work and to explore new directions. The Cart used ... View full abstract»

    Recent advances in system design provide increasing opportunities for rapid experimentation with task-oriented architectures, i.e., architectures designed to perform extremely well for a given application. Problems encountered in one such experiment indicate that, contrary to initial expectations, only a small fraction of the effort is required for hardware development. Most of the effort was devo...

    Data are given on the nature of the singularities near the tip of a sharp metallic cone, and on the structure of the singular fields. Electric and magnetic fields are considered separately, as they become infinite according to different laws. View full abstract»

    The Roytman and Swamy method of circuit diagnosis is one of many available results found within the reference node r model suggested in this paper. This model provides a focal point upon which concepts including the node-pair functions, the driving point, and transfer relationships can be evaluated. View full abstract»

    A portable X-ray computed-tomography (CT) scanner has been developed for the nondestructive measurement of cross sections of live trees, wooden utility poles, wooden building columns, wooden statues, etc., in the field environment. Temporal resolution of CT reconstruction is good enough for observing details of annual rings of trees. The scanner shah be useful in plant physiology, environment asse... View full abstract»
