AGV guidance system simulations with a programmable robotics kit

摘要

This paper gives an analysis of automated guided vehicles navigation systems. Two types of guidance are analysed and simulated by using Lego Mindstorm NXT package - fixed-path guidance through line following as the oldest type and vision-based guidance as a low-cost guidance system that utilises mobile phone camera for tracking marks and detecting obstacles. On the basis of theoretical studies and experience, robot can be programmed in the programming language RobotC in order to demonstrate the functionality of real AGV vehicles.
