Today the field of robotics is gaining popularity, because of their intelligence. These robots are performing a variety of activities in different fields. In this new era of robotics, continuous path tracking robots are drawing much importance because of their sophisticated closed loop control with completely automation features. The robot deigned here is also controlled through android device via WiFi. The main theme of this project work is design and develop a robot that can be operated as a line following robot as well as control the robot through android device for reading different parameters like obstacle, pit detection and fire sensing. The robotic vehicle designed here follows the line/path marked with black paint in a closed loop and senses the parameters that are constructed with sensing circuits on the vehicle. The path sensing sensors are arranged at the front bottom end of the vehicle and DC motors are used to drive the wheels. The microcontroller used in this project work is programmed to control the motors independently. Two DC motors with reduction gear mechanism are used to drive the robot and depending up on the control signals received in the input through the sensors or the android device; the output is controlled by the controller. The two DC motors are connected to the rear wheels of the vehicle for the vehicle movement. The required power supply for the vehicle is provided through the high power rechargeable battery of 12V. The advancement of technology has made possible the implementation of embedded systems in each and every field. This has added new capabilities and features. However most of the time, the Implementations are proprietary and networking is not always possible. Yet there is an increasing demand for advancements, where devices react automatically to changing environmental conditions and can be easily controlled through one common device. This project work presents a possible solution whereby the user controls the robot for fire sensing, pit or obstacle sensing by a mobile phone through its android interface. This results in a simple, cost effective and flexible system, making it an excellent feature for future smart robotic operations. The robot is designed to move freely in all directions and all required devices including heavy-duty battery is arranged over the chassis of the vehicle. DC motors with reduction gear mechanism are used to drive the vehicle, with the help of sensing circuits pits, obstacles and fire are sensed and will be informed to the android device that are connected through WiFi.
