Machine reliability, safety and environmental tolerance

The reliability of a TELEMAN (robot) machine is affected by environmental factors such as dust, water, vibrations, heat, and ionizing radiation. The effects of many of these factors on the components and materials in question are well known, but knowledge is missing about the effects of large doses of ionizing radiation (1E6 Gy) which were relevant.

Reliability analysis tools have been developed in order to incorporate radiation degradation in the analyses. Reliability analyses have been carried out for a number of robot types and a number of reliability data have been collected.

A widely representative range of components and materials have been radiation tested and the test results have been collated in the TELEMAN database along with data provided by the participants from their earlier work. Radiation data handbooks (2) have been written and published by Siemens and AEA Technology using information generated within the project. Data has also been exchanged with the corresponding radiation tolerance database run by the European Space Agency. The data has been disseminated to the other TELEMAN participants through a regular newsletter and on floppy disc.
Exploitation
The results of the project are already being exploited through radiation testing of components other TELEMAN projects. In addition, the data has been exchanged with the European Space Agency, and two radiation data handbooks have been published, ensuring broad exploitation of the results. The TELEMAN TM48 - INGRID robust gantry-mounted manipulato research project is also exploiting results from TM41 - ENTOREL to assess the reliability of the integrated research machine.
