Simultaneous teleoperation of multiple social robots

摘要

Teleoperation of multiple robots has been studied extensively for applications such as robot navigation; however, this concept has never been applied to the field of social robots. To explore the unique challenges posed by the remote operation of multiple social robots, we have implemented a system in which a single operator simultaneously controls up to four robots, all engaging in communication interactions with users. We present a user inter-face designed for operating a single robot while monitoring several others in the background, then we propose methods for characterizing task difficulty and introduce a technique for improving multiple-robot performance by reducing the number of conflicts between robots demanding the operator's attention. Finally, we demonstrate the success of our system in laboratory trials based on real-world interactions.
