Abstract

This paper introduces a novel robotic platform, called RASA (Robot Assistant for Social Aims). This educational social robot is designed and constructed to facilitate teaching Persian Sign Language (PSL) to children with hearing disabilities. There are three predominant characteristics from which design guidelines of the robot are generated. First, the robot is designed as a fully functional interactive social robot with children as its social service recipients. Second, it comes with the ability to perform PSL, which demands a dexterous upper-body of 29 actuated degrees of freedom. Third, it has a relatively low development cost for a robot in its category. This funded project, addresses the challenges resulting from the at times divergent requirements of these characteristics. Accordingly, the hardware design of the robot is discussed, and an evaluation of its sign language realization performance has been carried out. The inspected recognition rates of certain signs of PSL, performed by RASA, have also been reported.
