Autonomous mobile machines are applied increasingly often in outdoor applications where logistics can be arranged effectively and safety issues can be solved. Many new technologies are related to safety systems and a failure of a safety system can be hazardous, since they should prevent from accidents, theirs failures can be critical and the users trust them. These factors are important when considering new risk sources of autonomous mobile machines.
The aim of this study is to help safety assessors and designers to find new risk sources, which are additional to conventional mobile machine hazards. Autonomous systems are complex and risk sources are difficult to recognize. Systems include new technologies in safety systems and in control and communication systems. System complexity increases also possibilities of human errors. Therefore, risk assessor or designer of an autonomous mobile machine system need advice to find risk sources, in order to minimize risks to adequate level. The main result of this study is a checklist of new risk sources or hazards of autonomous mobile machines is presented and discussed in this article.
