Abstract

This study presents an alternative way to control Automated Guided Vehicles (AGVs) by designing, implementing, and testing both hardware and software solutions for the realization of a network-controlled AGV. A line-following AGV was constructed to represent AGVs in general. The hardware solution for network control involved the use of the Tiny Internet interface (TINI) module of Dallas Semiconductor. A TINI-based web server application and a client-based Graphical User Interface (GUI) applet were written in the Java programming language, and comprised the software solution for this study. The AGV was also given a wireless link to the network by using an 802.1lg wireless networking device. The network-controlled AGV was tested in a local area network setup. A five-station track was laid out on the floor for the AGV to follow. Computers on the network setup were then allowed to connect to the AGV via their web browsers to give out commands to the AGV; such as commands to tell the AGV which station to go next, commands to set the motor speed of the AGV, etc. The designed network-controlled AGV performed as expected. The only problem encountered was that of losing some serial frames over the network. This could be attributed to the omission of a hardware-based flow control on the serial communication between the ATMEGAIO microcontroller core of the AGV and the TINI module. The results of this study can become the foundation for giving AGVs, as well as any industrial robot, a globalized control scheme by interfacing them to a much wider network such as the interne.
