Voice-Controlled Typesetting Robot of ...

Humanoid robots are moving from the factories into our homes to imitate human actions or to do works in our daily life. Thus, the interaction between users and humanoid robots becomes more and more important in these applications. On the other hand, more and more applications of robots help people in training or education. This work has designed a voice-controlled typesetting robot of alphabet letters which can help those physically disabled to select the alphabet letters they want by voice as well as help with the learning of English letters for children. A simplified prototype of such design has been proposed in this paper. By a proper arrangement of microphone, actuators and mechanism structure, the chosen alphabet letters by voice input can be displayed by typesetting of bricks within a 3X3 grid plate via the operation of a robotic arm. Some experimental results are given to validate the satisfactory performance. Besides, 20 children between 2 and 5 years old are randomly chosen to play with this prototype and a primary conclusion is therefore summarized also shown in the proposed paper.
