There are two commercially accepted methods of force control used in automated surface finishing today. The first method, “through‐the‐arm” force control, applies force using the position of all the robot axes in unison. The second method, “around‐the‐arm” force control, uses the...

Describes the benefits of using robots for advanced composite lay‐up procedures. Particular emphasis is on aerospace structures. Argues that the use of robots now makes viable many fabrication operations that were previously too expensive, and highlights the improved quality afforded by...

The current state in the application of lasers for cutting and welding is reviewed. Most cutting operations are performed on specifically developed laser machine tools such as the Trumpf Lasercell and its application in the development of trim shapes and low volume panel production at a...

Reviews the 16th International Symposium on Automation and Robotics in Construction held in Madrid, Spain, in September 1999; outlines robotic projects relating to construction activities.

The article summarises the results of two projects undertaken within the framework of the European Union Brite‐Euram programme. Describes the problem of automating railway carriage production. Explains the solutions that have been developed for the welding and cutting processes that are...

There has been a considerable growth of interest in climbing and walking robots since the first international conference in Brussels last year. The two‐day event at Portsmouth University attracted speakers from 20 countries, a number of whom were able to report on machines that have been built...

Describes the experience of setting up a cooperative arm system based on individual open‐architecture controllers. Two six‐degree‐of‐freedom industrial manipulators, one of which is mounted on a moving track, are installed to realize a cooperative experimental set‐up. The main issues...

A discouraging problem regarding the use of robots within production processes is the perception by designers of single, unique products (such as buildings) that a manufacturing approach, reliant upon high levels of standardisation, constrains design creativity. An alternative approach, based...

Manipulators in one form or another have been in existence for many hundreds of years with the design usually motivated by the task to be undertaken. Most often in robots this has led to a simple two fingered claw mechanism which has been adequate for many tasks but when the problem domain...

Fieldbus has been used to control self drill drive screw (SDDS), spot clinching and self pierce riveting tools mounted to a single robot with a tool changer. This has reduced wiring complexity and enabled more robust cable dressing. The network, tool operation and tool changer are described.
