Procedure of Experiment. 2 All measurements took place at the Faculty of Electrical Engineering, University of Ljubljana, in the Laboratory of Robotics. Participants were asked to come to the faculty where they were accepted by the executive researcher from the Departments of Psychology and Robotics. First, the researcher from the Department of Psychology explained the purpose of the study and its framework. Before starting, the participants read and signed the informed consent that was necessary for participation in the study. The participants then filled in demographic questions. This part of the procedure took approximately 10 minutes. Participants were asked to sit down at a table, which was their working space. There was also a robot on the table and all the peripherals (Figure 4 and Figure 5). On the left side of the working area sat a researcher who operated the robot, and on the right a researcher from the Department of Psychology, who was writing down the participants' answers about their feelings (Figure 6). An electrical engineering student also participated in the experiment, who helped with preparing the work tools. Participants were first briefly introduced to the course of the experiment. They were told that they will participate in two work scenarios, one imitating the industrial environment and the other the laboratory environment. Within these scenarios, they will perform different steps of the task, and after each trial, they will report about their level of pleasure and arousal, how safe they found the robot’s movement, and to what extent they would be willing to work with the robot in the future. Participants then began the experiment with the industrial or laboratory scenario. The researcher first introduced them to all five steps of each situation. All the steps of both scenarios are presented in detail in Deliverable 2.2. Participants had a trial practice before each of the scenarios to familiarize themselves with the workflow. Before each trial, the researcher once again explained to the participants the course of the task so that the participants knew what the robot would do and what their task was. This part of the experiment took half an hour on average. After the experiment, participants were asked to share observations, feelings and experiences they had during the experiment. The executive researcher from the Department of Psychology wrote down their observations (Figure 6). The executive researchers thanked the participants for their time and coopera...
