通常製造業者都擁有物料倉庫，在製造流程中的前置作業是作業員將需要的零件逐一從倉庫中取出，因為零件形狀不一致，難以避免人力作業，會因此花費大量時間執行作業，所以本文提出新的揀料系統雛型，能夠協助指引作業員更有效率的執行揀料作業；本文提出利用物聯網技術開發之揀料系統雛型，本系統將揀料資訊電子化，並提供物料和揀料單管理系統，系統可將資訊透過路由器轉發給終端設備，其終端設備以Arduino實現，路由器以Raspberry Pi實現，終端設備安裝於各個櫃位顯示物料名稱和剩餘數量，路由器安裝於每排貨架，負責當排櫃位的資訊轉發，在揀料作業中以燈號提示應撿物料位置，作業員能夠依照燈號位置依序揀料，並透過終端裝置即可將作業進度回饋至伺服器系統，由伺服器系統管控揀料作業，以減少作業流程加快作業員揀料的效率 ，並可以藉由伺服器系統蒐集之訊息規劃倉庫。

Usually manufacturers have a parts warehouse, preparation in the manufacturing process is where workers take out components one by one from the warehouse, because the components are not the same shape, human work cannot be avoided, it will spend a lot of time to perform the job. Therefore, this paper proposes a new prototype of picking system, to help worker’s picking operations more efficient. This paper proposes to use IoT technology development prototype of picking system, The system electronically picks up information, and provide materials and picking list management system, the system can be transmitted to the terminal through the router information devices, including Arduino terminal devices to achieve, the router to achieve Raspberry Pi, the terminal installed in each counter Display the name of the material and the remaining quantity, the router is installed in each row of counters, responsible for the information forwarding when the counters. Besides, the location of materials which should be picked, will light signal, worker can follow the prompts pick up the location of materials, improve the efficiency of the worker picking.
