The emergence of steam and microelectrical machines in society gradually expanded since the era of the Industrial Revolution. Up until now, human beings have already co-existed with these machines for more than two centuries, and contemporary laws have developed preventional regulatory frameworks. These frameworks are based on risk assessments to supervise the safety of microelectrical machines which include automobiles, railway systems, elevators and industrial robots, etc. Regulators, especially South Korea and Japan expect human-robot co-existence societies to emerge within the next decade. These next generation robots will be capable of adapting to complex, unstructured environments and interact with humans to assist them with tasks in their daily lifes. Unlike heavily regulated industrial robots that toil in isolated settings, next generation robots will have relative autonomy, which raises a number of safety issues that will be the focus of this dissertation. The author’s purpose is to propose a theoretical legal framework on safety governance for service robots, and the core concerns are regulatory issues regarding the Open-Texture Risk.
