Driving control module for low cost industrial automated guided vehicle

Abstract

Automatic Guided Vehicles (AGVs) are computer-controlled “driverless” mobile vehicles equipped with optical, magnetic or laser guidance systems for automated functionality, categorized as either load carrying or load towing. AGV consists of several parts, such as the frame for pulling or lifting weights, movement balancer wheels, battery housing, collision avoidance sensors, driving module and others. But, the most important part of AGV is the driving module which is a module that functions as a movement guide, consisting of path detection sensors, driving motors and controllers. This Paper presents low cost a driving control module for low cost AGV that used in automotive manufacture industry. The AGV uses Raspberry Pi instead of PLC as controller, infrared sensor to detect line and industrial standard brushless DC (BLDC) motor as main actuator. PID control applied in the movement of the BLDC motor speed so that the AGV can follow the path smoothly and precisely. As a result, the AGV can follow the path with speed 30 m/min on a straight road and 30 m/m at a turn with a deviation 5 mm off the track.
