AGVs Task Management with Occupancy Grid Map for Foam-Manufacturing In-Plant Transport

Abstract

AGVs are increasingly used in the automated warehouse with a high demand for changing traditional workflow management to industrial 4.0. The heart of the computerized system is the central software that can distribute work functions from the queues and manage the AGVs’ traffic. On the 2D floor plant layout and the occupancy grid map, the RFID girds are initially from marked points or the place that AGVs have to transit to do an assigned task. This research proposes autonomously generating paths via four nearest grids and path switching scenarios. The results show the generated paths with sequential tasks concurrently in random conditions. The task management method can prevent the AGVs’ crash and bottleneck from the operation of nine machines in the foam manufacturing plant.
