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 robotactuated laser system. Sensor Review reports on these recent developments
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 hostile environments, and it yields output easily processed by digital electronics.
This report describes the progress that has been made to date on burn detection by acoustic emission with twoinch camshafts produced for V6 and V8 engines on a Norton camomatic grinding machine used for finish grinding valve cams.
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 a conventional robot.
Relatively simple and standard sensing equipment is quite adequate for some quite advanced and productive applications with robots, as has been demonstrated at the Cranfield Robot Automation Group. Jack Hollingum went to find out about it from David Williams.
Through a unique design and application of a photoelastic material a gripper was developed that was able to perform high precision assembly tasks with a robot on ultra thinwalledRT300.
Eddy current and ultrasonic sensing have potentially large advantages over vision systems for guidance of arc welding, except with very complex geometries. They are simpler, less expensive, and eddy current is immune to fumes from the arc. The authors review work currently in progress at Oxford.
The Robotics Research Unit at the University of Hull is engaged in work on robotic assembly problems using various sensory techniques.
Cracked screw heads have, as this paper describes, been automatically detected by a solid state electronic linescanning camera. The equipment which includes an automatic feeding system and fibre optic component illumination is controlled by a microprocessor.
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 cameras. Economics of scale, and the offer by Polaroid of a special designer's kit, have encouraged a great many experimental...
