Table of contents

Major advance by British company in automatic laser processing

To date lasers have not been used to their full capacity in industrial applications. However the situation could change as a British company is developing a commercial…

Proximity sensing uses re·entrant loop magnetic effect

G. Beni, L.A. Hornak, S. Hackwood

Advantages claimed by the authors for this type of magnetic sensor for embedding in robot fingers are that it is independent of the rate of approach, it is reliable in…

Camshaft grinding burn detection by acoustic emission

D.A. Roberts, D.L. Leete

This report describes the progress that has been made to date on burn detection by acoustic emission with two‐inch camshafts produced for V6 and V8 engines on a Norton…

Grabbing moving objects with visual feedback

Daniel Gelbgras, Marc Bogaert

This paper describes a system to grasp oscillating shock absorbers on a variable speed aerial conveyor. The system includes a set of cameras and a gripping tool mounted on…

Simple solutions trace complex surfaces

Relatively simple and standard sensing equipment is quite adequate for some quite advanced and productive applications with robots, as has been demonstrated at the…

A gripper for ultra·thin·walled tubes with a built·in force sensor

Y. Tur‐Kaspa, Sunrise Robotix, E. Lenz

Through a unique design and application of a photo‐elastic material a gripper was developed that was able to perform high precision assembly tasks with a robot on ultra…

Eddy current and ultrasonic sensors for robot arc welding

M.P. Howarth, M.F. Guyote

Eddy current and ultrasonic sensing have potentially large advantages over vision systems for guidance of arc welding, except with very complex geometries. They are…

A multi·processor system for sensory robotic assembly

I. Mitchell, D.G. Whitehead, A. Pugh

The Robotics Research Unit at the University of Hull is engaged in work on robotic assembly problems using various sensory techniques.

Detection of cracked screw heads using a linescan camera

C. Wallis, I.T. Franks

Cracked screw heads have, as this paper describes, been automatically detected by a solid state electronic linescanning camera. The equipment which includes an automatic…

Low·cost ultrasonics finds industrial use

Two other articles in this issue of Sensor Review make mention of the Polaroid ultrasonic rangefinding equipment which was originally developed for the company's own…

Sensing down on the farm

Publication last month by the Agricultural Research Council of a report dealing with future needs for sensors highlights the need and opportunities for exchange of ideas…

Vehicle finds its own way with mixed sensing

Using a variety of sensing methods the mobile robots laboratory at the University of Warwick is developing a free‐ranging vehicle for use in factories and stock yards.
