Friendly Elevator Co-rider: An HRI Approach for Robot-Elevator Interaction

In-building cross-floor delivery has always been a common daily task for business, but its robot-oriented automation has never been a popular convention due to the high infrastructural or developmental cost and the difficulties of having physical elevator-ride for common robots. This paper thus aims to contribute a universal robot-oriented elevator-ride workflow that adopts different visual and audible human-like touchpoints to achieve automated robot-elevator interaction, while ensuring the physical safety and emotional security of surrounding pedestrians and elevator passengers. Investigating the handling for potential elevator-ride scenarios and observing the interactions between humans and the robot under the influence of such human-like touchpoints, this paper offers empirical suggestions as to how in-building travel of robots can be pedestrians and passengers friendly.
