Abstract

In this paper, we presented a cart which can automatically transport loads to the distribution center of the appointed indoor place, based on Raspberry pi 4. It can recognize the obstacles by using the ultrasonic sensors so that it prevents the collision and takes a detour. Further, we entered the direction control code in the RFID. It has installed at important points such as the intersections of the destinations, so that if the RFID reader of the cart senses the RFID, the cart would stop or change the direction. After the transportation, if the load cell(weight sensor) recognizes that the baggage is unloaded, the cart returns to the initial point and would be retrieved. Therefore, we embodied the transportation cart which reduces the use of manpower and solves the problems conveniently across the transportation strategies.

본 논문에서는 물류센터나 실내의 정해진 위치까지 짐을 자동으로 운반할 수 있는 카트를 라즈베리 파이4를 기반으로 구현하였다. 카트는 초음파 센서를 이용하여 장애물을 인식해 충돌을 방지하고 우회한다. RFID에 방향 제어 코드를 입력해 교차로나 목적지 등 주요 포인트에 설치하였고, 카트의 RFID 리더기가 RFID를 인식하면 정지하거나 상황에 따라 방향을 전환할 수 있도록 하였다. 운송이 끝난 후, 로드 셀(무게추 센서)이 물건이 내려짐을 인식하면 카트가 다시 출발 지점으로 돌아와 회수된다. 카트는 운송 과정에 필요한 인력의 소모를 줄이고 운송 과정을 편리하게 해결할 수 있도록 구현하였다.
