Maintainability analysis of mobile robot

Abstract

Maintainability analysis is used to improve the efficiency of the robotic system based on the adequate maintenance strategy. In this paper, the maintainability characteristics and the critical failure modes of the system with respect to repair frequency and duration were identified. Data collection from the robotic system and their analysis were valid for a period of thirty four months. Furthermore, the maintainability and repair rate modes for all failure modes were calculated. Moreover, maintainability for different time periods at failure level and the entire system have been estimated on the basis of fitted distribution models. This study is anticipated to serve as a valid data source for robotic systems product manufacturers to improve the design and operation of their systems.
