Abstract

The development of automated work machine systems towards autonomous operation is proceeding rapidly in different industrial sectors. The aim of the study was to explore the current situation and possible differences in standardization supporting the development in different industrial sectors. The existing ISO and IEC standards and work items related to autonomous machinery were reviewed as well as activities in international industry groups regarding automation and autonomy of machinery. In general, the current standards are made mostly for machine manufacturers, but the views or responsibilities at worksite level are not considered. Three different approaches for safety concepts for different operating conditions were identified. One of them relies on onboard safety systems including sensor and perception systems for indoor applications. One guides to separate and isolate the autonomously operating machinery and to use access control to the autonomous operating zone. The third one is relying mainly on the machine operator's ability to understand the situation and to react correctly according to the available information. From technology point of view there seems to be a gap between the safety requirements set in standards and the state of the art in currently available technology.
