Abstract

Automating the welding of custom‐built large structures becomes increasingly necessary due to the growing shortage of manual welders and competition from low‐wage countries. A consortium funded by the European Community is developing the technology necessary to make this possible.

Development and demonstration of an autonomous, mobile welding robot capable of fabricating large‐scale customised structures.

Abstract

Purpose

Development and demonstration of an autonomous, mobile welding robot capable of fabricating large‐scale customised structures.

Design/methodology/approach

An autonomous welding robot has been developed under the EC Framework V Growth program. The system comprises a global vision system for part location and orientation, and a robot transport vehicle (RTV) which carries a 6‐axis robot, robot controller, welding equipment, and local sensors at the welding torch. The RTV path, robot arm motion and weld process programming are performed automatically using sensors and specially customised simulation software.

Findings

The technology developed within the project was demonstrated, in November 2004, to be capable of identifying and welding large scale customised structures as found in the earth moving equipment and bridge fabrication industries.

Research limitations/implications

The project demonstrated that current sensor technology is capable of being applied successfully to autonomous robots, but further developments in sensor technology are required to improve accuracy and joint access.

Practical implications

The NOMAD concept of autonomous mobile robots provides an alternative solution to welding mass customised structures.

Originality/value

This project demonstrated, for the first time, the capability of autonomous robots to weld large scale customised structures.

Abstract

Investors frequently make judgments and decisions in the presence of affect (i.e., mood or emotion). Investors' moods may influence the extent to which they incorporate available financial information in their investment judgments. I propose that investors interpret their moods as signals of the extent to which financial information should be processed to make investment judgments, but only when other, more direct signals regarding the need for in-depth processing are unavailable. Consistent with research in psychology, my experimental results suggest that investors experiencing positive mood exert less effort to process available financial information than investors experiencing negative mood. Consequently, positive mood results in lower-quality financial judgments in my setting. However, when investors receive cues suggesting that initially received information is subjective, the effect of mood on effort to process financial information is mitigated. Overall, my results suggest that factors associated with positive investor mood (e.g., positive market sentiment) reduce the depth of investor analysis and lower judgment quality absent signals regarding the subjectivity of financial information.

Abstract

‘A MAP OF THE WORLD that does not include Utopia is not worth glancing at’ wrote Oscar Wilde. ‘It leaves out the one country at which humanity is always landing. And when it lands there it looks out and, seeing a better country, sets sail again. Progress is the realization of Utopias’.
