So the AssistMe project is finally over. AssistMe was a 3-year long endeavor to develop an industry 4.0 system for human-robot cooperation in a factory environment. The iterative development of the system featured (1) an off-the-shelf robotic arm controlled via a touch- panel (remote-control), (2) a robotic arm featuring physical human-robot interaction (pHRI), and (3) a robotic arm featuring a tangible user interface (TUI) for control. Each iteration step was evaluated by five industry workers for two different use cases. We used established analysis methods, namely behavior observation and User Experience (UX) questionnaires. The goal of the project was to find out (a) if there is a difference in the UX between the different robot versions, and (b) to identify improvements over time, as well as open questions and dead-ends in order to (c) provide concrete suggestions for future robot-human cooperation in the Industry 4.0 context. Our user studies revealed an improvement over time of UX in terms of usability, temporal demands, and performance expectancy based on concrete ergonomic, supportive artificial intelligence, and intuitive simplified interaction.
