微型電磁塔吊夾娃娃機

Abstract

本專題的目的為製做一個類似於夾娃娃機取物功能的機構，並在過程中結合跨領域知識來完成此作品。本題目使用了精確規格的機械部件搭配3D列印製成之零件為機構，以確保操作時的精準度及流暢度；並自行設計驅動電路來驅動步進馬達使機構運作，如此整合製做出一個類似於塔吊的單懸臂取物機構。 此機構使用8051單晶片微控制器，透過驅動電路驅動三顆步進馬達，各別控制懸臂的左右旋轉、電磁鐵的前後及上下移動；並使用連座的線性軸承來帶動電磁鐵的移動，以使之到達準確位置來吸取物品，達成機構在特定空間內抓取物品並放置到目的地位置的功能。未來亦希望能延伸應用此機構在機械手臂及其他需要精密操控的儀器中。

The aim of this project is to design and implement a scaled-down tower crane that can grab and move objects to the specific destination. In order to ensure the accuracy and freedom of operating mechanism, most of mechanical parts are made in accurate specification and combined with parts made by 3D printer to assemble the mechanism. In addition, a stepper motor driver is designed and implemented in this project. By integrating these materials and techniques, a mechanism which possesses the functions of a tower crane is completed. In this project, an 8051 single-chip microcontroller is employed to drive three stepper motors to fulfilled the functions of hoist, crane and claw. The stepper motors control the movement of the electromagnet arm (back and forward, left and right, up and down), and use the linear bearings with dock to help driving the electromagnet, in such a way to move objects accurately within the specific area. In future, we hope the method and the concept of this project can be used in mechanical arms or mechanical equipments that need precise operation.
