This book was released on 1983 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors developed a noncontact proximity sensor which can measure the distance and orientation of a surface in a range of four to five centimeters. The sensor is based on the scheme of active illumination and triangulation. It uses multiple infrared LEDs(light emitting diodes) as the light sources and a PIN-diode area sensor chip for detecting the spot positions. Six LEDs with optics for collimating the beam are mounted at the sensor head. The directions of the beams are aligned to form a cone of light converging at a distance of 4.5 cm from the sensor head. As each LED is sequentially pulsed, the sensor chip detects the position, in its field of view, of the spot projected by the LED light beam on the object surface. The 3-D location of the spot on the surface can be computed by triangulation. By doing this for six LEDs a set of six 3-D points is obtained. Then by fitting a plane to those points, the distance and orientation of a small portion of the object surface are calculated. Since there is no moving part and the spot position sensor chip is a analog sensor which outputs the position of the spot directly without scanning its field of view, fast operation of the proximity sensor can be realized. Currently the sensor can give approximately 1000 measurements of distance and orientation per second with precision of 0.07 mm for distance and 1.5 deg for surface orientation. This non-contact proximity sensor will be useful for such applications as tracing an object surface by a robot arm with specified distance and orientation relative to the surface. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The use of sensor's with machines, whether to control them continuously or to inspect and verify their operation, can be highly cost-effective in particular areas of industrial automation. Examples of such areas include sensing systems to monitor tool condition, force and torque sensing for robot assembly systems, vision-based automatic inspection, and tracking sensor's for robot arc welding and seam sealing. Many think these will be the basis of an important future industry. So far, design of sensor systems to meet these needs has been (in the interest of cheapness) rather ad hoc and carefully tailored to the application both as to the transducer hardware and the associated processing software. There are now, however, encouraging signs of commonality emerging between different sensor application areas. For instance, many commercial vision systems and some tactile systems just emerging from research are able to use more or less standardized techniques for two-dimensional image processing and shape representation. Structured-light triangulation systems can be applied with relatively minor hardware and software variations to measure three-dimensional profiles of objects as diverse as individual soldered joints, body pressings, and weldments. Sensors make it possible for machines to recover 'sensibly' from errors, and standard software proce dures such as expert systems can now be applied to facilitate this.

This book was released on 2012-12-06 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at the NATO Advanced Research Workshop (ARW) on "Sensors and Sensory Systems for Advanced Robots", which was held in Maratea, Italy, during the week Apri I 28 - May 3, 1986. Participants in the ARW, who came from eleven NATO and two non-NATO countries, represented an i nternat i ona I assortment of d i st i ngu i shed research centers in industry, government and academia. Purpose of the Workshop was to rev i ew the state of the art of sensing for advanced robots, to discuss basic concepts and new ideas on the use of sensors for robot control and to provide recommendations for future research in this area, There IS an almost unanimous consensus among invest i gators in the fie I d of robot i cs that the add i t i on of sensory capabi I ities represents the "natural" evolution of present industrial robots, as wei I as the necessary premise to the development of advanced robots for nonindustrial app I i cat ions. However, a number of conceptua I and techn i ca I problems sti I I challenge the practical implementation and widespread appl ication of sensor-based robot control techn i ques. Cruc i a I among those prob I ems is the ava i lab iii ty of adequate sensors.

This book was released on 2012-12-06 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design of intelligent robots is one of the most important endeavors in robotics research today. The key to intelligent robot design lies in sensory systems for robotic control and manipulation. In an unstructural environment, robotic sensing translates measurements and characteristics of the environment and working objects into useful information. A robotic system is usually equipped with a variety of sensors to perform redundant sensing and achieve data fusion. This book contains revised versions of papers presented at a NATO Advanced Research Workshop held in Florida in September 1989 within the activities of the NATO Special Programme on Sensory Systems for Robotic Control. The fundamental issues addressed in this volume were: - Theory and techniques, including knowledge-based systems, geometrical fusion, Boolean fusion, probabilistic fusion, feature-based fusion, error-estimation approach, and Markov process modeling. - General concepts, including microscopic redundancy at the sensory element level, macroscopic redundancy at the sensory system level, parallel redundancy, and standby redundancy. - Implementation and application, including robotic control, sensory technology, robotic assembly, robot fingers, sensory signal processing, sensory system integration, and PAPIA architecture. - Biological analogies, including neural nets, pattern recognition, low-level fusion, and motor learning.
Download or read book Design of an Optical Proximity Sensor Using Multiple Cones of Light for Measuring Surface Shape written by Michael Fuhrman and published by . This book was released on 1984 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A noncontact multi-light source optical proximity sensor which can measure the distance, orientation, and curvature of a surface has been developed. Beams of light are sequentially focused from the ends of fiber optic cables onto a target surface. An analog light-sensor- a planar PIN diode area sensor chip - measures the position of the spots of light on the surface, and the 3-D locations of the spots are computed by triangulation. By fitting a surface to a set of points, the distance, orientation and curvature of the target surface is calculated. The number of light sources, and their positions and orientations were chosen so that the uncertainty in the measurement of distance would be within 0.05 mm and the uncertainty in surface orientation would be within 1.0 deg. Since there are no moving parts and the spot position sensor chip outputs the position of the spot directly without scanning its field of view, fast operation of the proximity sensor can be realized. Earlier prototype versions of the sensor can give approximatley 1000 measurements of distance and 1.5 degrees for surface orientation. This proximity sensor will be useful for such applications as tracing an object surface by a robot manipulator with a specified distance and orientation relative to the surface. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Precision agriculture is now 'main stream' in agriculture and is playing a key role as the industry comes to terms with the environment, market forces, quality requirements, traceability, vehicle guidance and crop management. Research continues to be necessary and needs to be reported and disseminated to a wide audience. This book contains peer reviewed papers presented at the 9th European Conference on Precision Agriculture, held in Lleida, Spain. The papers reflect the wide range of disciplines that impinge on precision agriculture: technology, crop science, soil science, agronomy, information technology, decision support, remote sensing and others. The broad range of research topics reported will be a valuable resource for researchers, advisors, teachers and professionals in agriculture long after the conference has finished.
