GPS-Guided Mobile Robot

Published on 19 May 2022. Written by Vasanth Vidyakar

The main objective of this project is to build a modular mobile robot that can navigate around its way using GPS. The primary component of this robot is its navigation system, with an augmented GPS system integrated to provide the local coordinates and help in positioning of the robot. It can be programmed to carryout multiple functionalities.

The project comprises of two major parts, one is the robot chassis fabrication with all the sensors and another is the navigation system comprising the GPS module. You can also build a mobile robot that uses only GPS as its sensor and can make it way through the field by navigating via GPS coordinates. The accuracy of the robot’s motion depends on the accuracy of the GPS. You need to program the microcontroller in such a way that the robot will move according the coordinates provided in the GPS module.

The robot can be made as an autonomous navigation and guidance system capable of moving along a sidewalk in an urban environment under the way-point navigation using a GPS receiver unit as its only sensor. The robot can further be modified in to an all-terrain robot that can provide a greater assistance to humans in hostile environments of military and defence. You can also add IR proximity sensors or ultrasonic sensors to make the robot avoid obstacles or detect the human presence.

Project Description:

Arduino Uno: The digital and analog input/output pins are equipped in boards that may be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
Voltage regulator: It is used to maintain a constant voltage level and also used for regulating AC or DC voltages. A voltage regulator contain negative feed-forward design or it may also contain negative feedback control loops.
DC Motor: This is an electric machines which converts electrical energy to mechanical energy. This is the most commonly used motor for the actuation of robots.
Ultrasonic Sensor: The ultrasonic sensor is used to detect the obstacles present in the location. This module will be constantly generating the ultrasonic waves and whenever the robot comes near the obstacle the waves will be reflected back and the receiver will detect it and sends the data to the microcontroller.
Piezo Buzzer: A piezo buzzer is a loudspeaker that uses the piezoelectric effect to generate sound. It has both a piezo disc and an oscillator inside. Whenever the buzzer is powered, the oscillator generates a frequency around 2-4 kHz and the piezo element vibrates accordingly to produce the sound.
GPS Module: The EM-406A GPS is a simple device used with the robot for determining the location using satellite, complex math and general relativity. The Honeywell HMC6352 digital compass is used to get the heading angle of the robot.
