This paper integrates information, mechanical, and electrical technologies to design an intelligent pyramidal manipulator for recognizing and writing handwritten-characters. In terms of mechanism design, we use the iGus pyramidal manipulator, which is a modular structure that can be assembled by yourself. The motion of the iGus pyramidal manipulator is controlled by an Advantech motion control module, in which we use three AC servo motors to drive three sliders and enable the end-effector moving in three-dimensional space. For character recognition, we adopt a convolutional neural network (CNN) for recognizing handwritten English letters and numbers, and then return the recognition results to the pyramidal manipulator via MQTT. After that, the pyramidal manipulator writes down the characters. Finally, through experiments, we verify that our pyramidal manipulator can accurately recognize handwritten characters and accurately write the character. |
