Labview Based Autonomous Agricultural Robot Using Fuzzy Logic Controller

Abstract

This study proposes a LabVIEW based autonomous agricultural robot which can be used for ploughing. The control logic is designed using fuzzy logic controller to operate the robot in autonomous mode. The robot can also be controlled from a remote place using internet and its position is monitored using Global Positioning System (GPS), Data Socket protocol and Wi-Fi connection. Two DC motors are used to achieve movement control of the robot and they are controlled by the designed fuzzy logic controller. This control logic has two loops. One is outer speed control loop and the other one is inner current control loop. Based on the present position of the robot, the reference speed value is generated and based on this reference speed value the movement of an agricultural robot is controlled. Laboratory Virtual Instrument Engineering Workbench (LabVIEW) is a graphical programming environment suited for system-level design. This LabVIEW software enables complex and expensive equipment to be replaced by simpler and less expensive hardware. The primary difference between natural instrumentation and virtual instrumentation is the software component of the virtual instrument.
