The aggregate using of a flexible automation system in the industry area is gaining increasing attention from researchers in the last two decades. The most important factors influencing the automation system are the interaction techniques and the communication facilities used at the production line. There are different interaction techniques that have developed rapidly over the recent years within different manufacturing area for the sake of improving performance and quality of product.
Automated Guided Vehicle (AGV) has been used as a flexible goods transportation tool at fac-tories. This work is aiming to test and introduce an adaptive communication technique be-tween an AGV and a production line's components using Radio Frequency Identification (RFID) system, which can be used in the manufacturing area.
In this report, related works and titles to understand and achieve the goal has been discussed. As a background, AGV, RFID and communication techniques have also been discussed.This project provides a solution on how AGV communicates with the robot in a production line by using RFID systems and sensors. The proposed solution has been imple-mented and tested in order to get applicable results. The implementation phase is done us-ing an AGV, robot, RFID system (RFID reader and tags) and raspberry pi (RPI). In addition, the software used to make this components work includes AGV program (to control the AGV), RAPID program (to program the robot) and C program (is used in the RPI to receive the data from the RFID reader and resend it to the robot).
The first test is conducted to determine AGV's accuracy, i.e. positioning accuracy or stop position in front of the robot. The importance of accuracy test helps in avoiding damage of goods and other unexpected consequences that can be caused by the lack of accuracy of the robot. Other tests aim to determine the suitability of the system and that the RFID, as a communication technique, is functioning properly.
Some major benefits of the provided solutions include testing and proving that RFID can be used as a communication tool in the production line especially in the transportation of goods between different worksites and the capability of using RPI as a coordinating tool instead of ordinary computers. This fact can contribute in increasing the flexibility of production lines.
