In a large number of human-robot interaction (HRI) studies, the aim is often to improve the social behaviour of a robot in order to provide a better interaction experience. Increasingly, companion robots are not being used merely as interaction partners, but to also help achieve a goal. One such goal is education, which encompasses many other factors such as behaviour change and motivation. In ...

The multi-robot manipulation task, where a team of robots cooperatively lift and move objects, is exceptionally difficult due to the synchronization between the robots. Although increasing the number of robots can expand the area that the robots can cover within a bounded period of time, a poor human-robot interface will ultimately compromise the performance of the team of robots. However, intr...

We want to reveal the usefulness of mobile robots by showing concrete applications in human daily life through this study. In this paper, our trials to realize several specific tasks are shown. The development of an Intelligent Escort Robot moving together with human is presented first. A teleoperated book browsing robot is described next. And finally, a network-based stationeries rental servic...

This paper describes a robot control architecture with an underlying human-robot interaction (HRI) model. The architecture is supported on an algebraic framework inspired in semiotics principles. The architecture is composed of a set of objects that capture, in the locomotion context, features often present in human-human interactions, namely ambiguity and semantics. The resulting framework dif...

Existing methodologies to describe anthropomorphism in human-robot interaction often rely either on specific one-time responses robot behavior, such as keeping the robot's secret, or post hoc measures, questionnaires. Currently, there is no method dynamics of people's behavior over course an and response behavior. In this paper, I propose a that allows researcher trace anthropomorphizing non-an...
