Automated Guided Vehicles (AGV) for Material Movement in Plants & Warehouses

Abstract

The American Society of Safety Engineers (ASSE) defined AGVs as Machines without drivers that can move along pre-programmed routes, or use sensory and navigation devices to find their own way around, Vehicles that are equipped with automatic guidance systems and are capable of following prescribed paths, driverless vehicles that are programmed to follow a guide path. The AGV robot described here is a PIC microcontroller based, and is developed with three degrees of freedom. (Light following, wall following & pit avoidance capability). The robot contains the USB 2.ocompliant PIC 18F455o microcontroller, motors, sensors, wheels, battery, etc. The robot uses four IR sensor modules and two LDR circuits. ALL the sensors of the robot are precise and sensitivity can be varied.
