Digital technology is becoming ubiquitous and embedded as an integrated part of our daily lives, in which the digital and the physical worlds are increasingly interconnected and intertwined. While advanced technology can provide tremendous benefits and opportunities, it can also be very complex and challenging to understand, potentially leading to fear, suspicion, and distrust. This paper investigates a case of human-robot interaction in cooperative manufacturing, focusing on understanding how operators, managers and viewers feel about cooperating with industrial robots using potentially dangerous tools like nail guns. The aim of the study is to identify how human reactions to technology-induced change can be understood. The research question is: how can different trigger points of fear or distrust in technology be understood in the context of human-robot interaction? The findings reveal three key factors in overcoming fear, creating trust and encouraging interaction: knowledge, control, and self-preservation. The main contribution is illustrated through suggested guidelines for aspects that have to be practically considered when building this type of flexible robot cell for interacting with industrial robots in a real setting.
