REALTIME OBSTACLE AVOIDING ROBOT CAR USING RASPBERRY PI

Abstract

In robotic car, real time obstacle detection and obstacle avoidance are significant issues. Design and 
implementation of a robotic car have been presented with regards to hardware, software and communication 
environments with real time obstacle detection and obstacle avoidance. Raspberry Pi platform, web applications and 
Wi-Fi technology have been used for implementation of the system. This robotic device has been developed with the 
interaction of web-based. Raspberry Pi has been used as the robot’s brain. The robot has many hardware 
components such as Ultrasonic Sensor, DC Motors, Relay’s, voltage regulator, capacitor, resistors and transistors. It 
also consists of the software component that uses a web application. The desired direction or mode by web 
application can be selected by the user of the robotic car. The user can control the robot movements from his/her 
own intelligent device or take the robot in automatic mode and let the car drive in its own way. Thus, the robot can 
flee from the obstacle and detect live objects. The purpose of this project is to alert the civilian and military to 
potential terrorist attacks especially in military areas with live detectable sensors.
