A Few Issues on Human-Robot Interaction for Multiple Persistent Service Mobile Robots

AI and robotics researchers aim at having robots in our environments coexisting with humans, as artificial creatures that will help humans and collaborate with humans to improve our societies. There will be more than one robot. Robots will not interact with some humans just once, or a few times, but many times. Humans will interact with robots to change their requests and to teach and correct their behaviors. This abstract briefly discusses a few issues for AI and HRI for such challenging repeated interactions in space and time between robots and humans. We have made different levels of research progress on these issues, as we discuss. Our presentation is motivated by our work with the CoBot mobile service robots, which have been running in our environments for the last three years, and for more than 500kms.
