Design and Realization of a Social Robot for Teaching Sign Language to Hearing-impaired Children Part One: Upper-body, Arms & Hands
, M.Sc. Thesis Sharif University of Technology ; Meghdari, Ali (Supervisor) ; Alemi, Minoo (Supervisor)
Abstract
This thesis covers the design and realization steps of the upper-body of RASA, a social humanoid robot to be used as a Persian sign language (PSL) teaching assistant. In the design and fabrication processes, three main requirments is defined. First requirement is the robot's ability to perform PSL. The second one is for the robot to posess the characteristics required for a social robot interacting with targeted groups of people. And the third one is for the robot to be realized with minimum required cost. Further design guidelines are generated based on these three requirements. Analysing the structure of Persian sign language, the kinematic layout of the upper-body of the robot, regarding...
Design and Implementation of Face Recognition System on Expressive Robot and Study of its Interactive Effects with Deaf Children
, M.Sc. Thesis Sharif University of Technology ; Meghdari, Ali (Supervisor) ; Alemi, Minoo (Supervisor) ; Taheri, Alireza (Co-Supervisor)
Abstract
Social robots are a group of robots designed and built to interact with humans, so the ability to interact emotionally in these robots, especially in interaction with people with hearing and speech disorders, is essential because these people do not have an emotional state sound. Therefore, in this research, an emotional interaction system based on recognizing the user's emotional state from his facial state using deep learning algorithms as well as performing an appropriate emotional response on the robot's face has been designed and implemented on an expressive social robot. In order to design the emotional state recognition system, first, the best model was found on the large AffectNet...
