Computers are already powerful enough to sustain useful robots that interact and assist humans in every-day life. However progress requires a scientific shakedown in goals and methods not unlike the cognitive revolution that occurred 40 years ago. The document presents the origin and early steps of the RUBI/QRIO project, in which two humanoid robots, RUBI and QRIO, are being brought to an early childhood education center on a daily bases for a period of time of at least one year. The goal of the RUBI/QRIO project is to accelerate progress on everyday life interactive robots by addressing the problem at multiple levels, including the development of new scientific methods, formal approaches, and scientific agenda. The current focus of the project is on educational environments, exploring the ways in which this technology could be used to assist teachers and enrich the educational experiences of children. We describe the origins, philosophy and first steps of the project, which included immersion of the researchers in the Early Childhood Education Center at UCSD, development of a social robot prototype named RUBI, and daily field studies with RUBI and QRIO, a prototype humanoid developed by Sony.

The design and development of social robots that interact and assist people in daily life requires moving into unconstrained daily-life environments. This presents unexplored methodological challenges to robotic researchers. Is it possible, for example, to perform useful experiments in the uncontrolled conditions of everyday life environments? How long do these studies need to be to provide reliable results? What evaluations methods can be used?In this paper we present preliminary results on a study designed to evaluate an algorithm for social robots in relatively uncontrolled, daily life conditions. The study was conducted as part of the RUBI project, whose goal is to design and develop social robots by immersion in the environment in which the robots are supposed to operate. First we found that in spite of the relative chaotic conditions and lack of control existing in the daily activities of a child-care center, it is possible to perform experiments in a relatively short period of time and with reliable results. We found that continuous audience response methods borrowed from marketing research provided good inter-observer reliabilities, in the order of 70%, and temporal resolution (the cut-off frequency is in the order of 1 cycle per minute) at low cost (evaluation is performed continuously in real time). We also experimented with objective behavioral descriptions, like tracking children's movement across a room. These approaches complemented each other and provided a useful picture of the temporal dynamics of the child-robot interaction, allowing us to gather baseline data for evaluating future systems. Fi-

Abstract-This paper introduces the early stages of a study designed to understand the development of dance interactions between QRIO and toddlers in a classroom environment. The study is part of a project to explore the potential use of interactive robots as instructional tools in education. After 3 months observation period, we are starting the experiment. After explaining the experimental environment, component technologies used in it are described: an interactive dance with visual feedback, exploiting the active detection of contingency and robotic emotion expression.Index Terms-humanoid robot, QRIO, the RUBI/QRIO project, toddlers, long-term interaction, engaging interaction, interactive dance, contingency detection
