  The foundation of this paper is an experiment of fifteen participants
interacting directly with an autonomous robot. The task for the participants
was to carry a table, in two different setups, together with a robot, which is
intended to support older people with heavy lifting tasks. By collecting and
analyzing observational, quantitative, and qualitative data the interaction was
investigated with a specific emphasis on trust in the robot. The overall aim
was a better understanding of people's emotional and evaluative reactions when
they engage with a functioning robot in a relatable everyday scenario. This
study shows that successful cooperative task completion has a positive effect
on trust and other related evaluations, like the perceived adaptiveness
regarding the robot's behavior.
