| dc.description.abstract | The purpose of this study aims to design an interactive educational robot with low-cost materials and parts. This robot is composed of two mechanisms. One is robotic head, and the other is robotic arm. To execute facial expression, the servo motors and servos are combined with the linkage structure for robotic head to control the movement point. The movement points are eyelid, neck, eye, eyebrow, and mouth. Subsequently, the robotic arm with 6 degree of freedom constructed by the acrylic frame is controlled by using the inverse kinematics and motion strategy.
This robot is capable of implementing the interactive and educational functions by cooperating with [1]. These functions are (1) English and math teaching, (2) the upper posture and facial expression imitation, and (3) color balls tracking and touching. Firstly, the robot can identify the pictures and math further control the robotic arm to array the right answer by inverse kinematics. Secondly, the robot can imitate the humans’ upper posture and facial expression by controlling the robotic head and arms. Finally, the robot can identify the color movement direction and adjust the motors installed in the neck by designing the fuzzy controller to continuously track the color ball. When the color ball stops, the robotic arm will touch the ball. After a series of experiments, the results show the robot to accomplish the three functions effectively. | en_US |
