Abstract—In this project, ‘AZ’ humanoid robot head is developed to assist elderly person in their daily life as a personal assistance. This paper provides the modeling and design of an electrically actuated head mechanism. Object and color tracking are considered in the design process. Considering performance of tracking capabilities leads to a total number of four degrees of freedom for the head mechanism, which are split into two main sub-mechanisms: the neck and the eyes. Modeling each sub-system is carried out and taken as inputs of the design process. The ‘AZ’ humanoid robot head using combination of two cameras and kinematics revolute joint movement which is actuated by servo motor that perform robot head movements concurrently. The tracking action of robot head is managed through graphical coding interface i.e labVIEW. The final outcome of this project will enable the robot to receive process and execute the command received from the elderly people.
