Navigation method of PLC based mobile robot

For centuries, the revolution in technology undoubtedly is the robot. Starting from dream of a man to be free of the drudgery of manual labor using automatic device, until currently in 21st century where robot has been applied to almost all types of labor industries. This project is motivated by the lack of application in Programmable Logic Controller (PLC) as mobile robot navigation system. By developing an algorithm and analyzing the navigation of mobile robot using PLC, the mobile robot should be able to follow line hypothetically. An experiment was conducted as the method to prove the hypothesis. Starting with designing the program using PLC software until assigning the PLC into the mobile robot with complete circuit wiring. To analyze the navigation of mobile robot, navigation experiment is done in straight line which is repeated for 5 times and represented in line graph. From 20 mark points measured for each running time, it shows that error is lest then 18% which prove that the mobile robot able to navigate using PLC. At the end of the experiment, the result showed the ultimate goal of this project has been achieved by moving the mobile robot using PLC based controller mobile system and enable the mobile robot to read and following the line.
