Human Trust After Robot Mistakes: Study of the Effects of Different Forms of Robot Communication Collaborative robots that work alongside humans will experience service breakdowns and make mistakes. These robotic failures can cause a degradation of trust between the robot and the community being served. A loss of trust may impact whether a user continues to rely on the robot for assistance. In order to improve the teaming capabilities between humans and robots, forms of communication that aid in developing and maintaining trust need to be investigated. In our study, we identify four forms of communication which dictate the timing of information given and type of initiation used by a robot. We investigate the effect that these forms of communication have on trust with and without robot mistakes during a cooperative task. Participants played a memory task game with the help of a humanoid robot that was designed to make mistakes after a certain amount of time passed. The results showed that participantsxe2x80x99 trust in the robot was better preserved when that robot offered advice only upon request as opposed to when the robot took initiative to give advice.

HumanRobot Team: Effects of Communication in Analyzing Trust Trust is related to the performance of human teams, making it a significant characteristic, which needs to be analyzed inside humanrobot teams. Trust was researched for a long time in other domains like social sciences, psychology, and economics. Building trust within a team is formed through common tasks and it depends on team performance and communication. By applying an online game based tasks for humanrobot teams, the effects of three communication conditions (communication without text and verbal interaction, communication with text and verbal interaction relatednot related to the task) on trust are analyzed. Additionally, we found that the participantsxe2x80x99 background is linked to the trust in the interaction with the robot. The results show that in a humanrobot team the human trust will increase more over time when heshe is working with a robot that uses text and verbal interaction communication related to the task. They further suggest that human trust will decrease to a lower extent when the robot fails in doing the tasks if it uses text and verbal communication with the human.
