現今科技日新月異的發展，自動化、無人化的應用也越來越普遍，許多的國家也相繼投入智慧型機器人之相關研究與運用，目的在希望提高工作或服務之效能，替代人類從事具危險或反覆性之工作，走入大眾社會，服務弱勢團體，讓生活能夠更便利，固衍生出各式各樣用途的機器人，例如工業應用上有機器人可以應用在焊接、運輸、裝配及各種加工。
本文研究目的想建構一台能夠分送郵件之機器人以節省各機關在傳遞公文上時間和人力的耗費，而現今之機器人的工作環境大多會侷限於同ㄧ平面或同ㄧ樓層，加上現今的建築物大多以樓層方式建構，這一個限制不但會使機器人的工作效率會大大的降低更會把機器人未來的應用侷限著，因此所建構的郵件機器人除了能夠傳送同ㄧ樓層之郵件給收件者外，還需能夠達到跨樓層傳送郵件之目的。本文透過筆記型電腦端和兩個PIC16F877單晶片之間的溝通進而控制郵件機器人完成送信的目的，在電腦端建構的人機介面可以用來選取收件者、建立環境地圖、路徑規劃、影像辨識、控制郵件機器人的運動方式等功能，並透過演算法計算出路徑規劃、影像辨識之結果分別傳送給單晶片PIC16F877去控制郵件機器人中各馬達間的相對運動。最後，我們以工科系館為實驗環境並以系館的老師作為送信對象，實際執行送信實驗測試。

Nowadays, technology has been changing so fast. The practices of the automation and non-people operation are getting more common. More countries devote into the correlation studies and practices of the intelligent robot. The purpose is to improve the efficiency of workings, and to substitute people of dangerous and repeatable work. The intelligent robot can serve the disadvantaged groups in the society. In order to make life more convenient, different robots are invented for various kinds of usages. For example, the robots can be used in soldering, transportation and assembling of industrial applications.
The purpose of this research is to construct a robot which can deliver mails for reducing time and man power among administrations. The working environment of robots today is confined to the same plane. Besides, most of the buildings are built by floors. This restriction lowers the working efficiency of the robots, and confines the roadmap of the robots. Therefore, the mail robots can deliver not only the same floor but also the whole building. The main point of this study is to control the robots to deliver mails through the connection betweens the notebook and a couple of PIC16F877 chips. The human-to-machine constructed by computers can be used to choose receivers, make environment map, plan path programming, do the image recognition and control the movements of the mail robots. The human-to-machine can transmit the results of the path programming and the image recognition to both PIC16F877 and the chips can control the relative motion of the motors. Finally, we use the building of engineering science as the experimental environments and take the professors as the attendees for the experiment.
