Objectives

The reliability of a TELEMAN machine is affected by environmental factors such as dust, water, vibrations, heat, and ionising radiation. The effects of many of these factors on the components and materials in question were well known, but knowledge was missing about the effects of large doses of ionising radiation (1000000 Gy) which were relevant here. Furthermore, there was a need to collect knowledge at system level, i.e. about complete TELEMAN machines. Components and materials which are especially susceptible to radiation damage are: electronics, sensors, fibre optics, signal communication systems, insulating materials, lubricants, and adhesives.
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.
Work to be done

In order to assess how much the various factors influence reliability, the "TELEMAN 41 - ENTOREL" project was to provide data as well as models for the calculation of the reliability of the machine as a function of time and exposure. Furthermore, failure strategies were to be developed to plan the difficult task of recovery of stranded machines. Reliability data already existing with the partners and elsewhere for relevant equipment was to be collated in a data base. Possible gaps in the existing data were to be covered by component or materials testing. Concurrently, reliability models as well as other models for the assessment of the behaviour of the machine were to be set up. A very important part of the work throughout the project was to be the collection of data and other information from internal and external (to TELEMAN) sources and the dissemination of this information as well as information generated by the project to the partners of all the TELEMAN projects.

Test strategy

Component and material testing was to be performed in order to complement data gathered from the partners in this and the other TELEMAN projects.
