Human-robot interaction of an active mobile robotic assistant in intelligent space environments

This paper presents techniques for system design and human-robot interaction of an active mobile robotic assistant for the elderly people in known, cluttered and dynamic indoor environments. The RFID-based intelligent space is proposed to automatically help users to attain desired services and prevent from possible accidents. A useful human-robot interactive system (HRI) is presented which includes facial expressions, event reminder and two nursing-care functions. An operational scenario is presented for showing how the robot interacts with the user. Experimental results are conducted to show the merits and effectiveness of the proposed techniques.
