Bluetooth Controlled Smart Robotic Car

Abstract

Robots are made to make human task easier. Line following mode is an amazing feature in a robotic car. Besides, when it is also equipped with more features like manual controlling, voice controlling and obstacle avoiding it becomes more advanced and useful for humans. There are so many task that are very hard or impossible for a human being to complete, but as a robot is a machine it can perform any task according to its capabilities without getting tired. And also robot can work all day long as long as it is getting enough power supply. Besides there’s no possibilities of death of a robot while doing any dangerous task as they have no sense of life or felling. It can be damaged, destroyed, broken but also it can be repaired. So a robot is a must needed machine now a day. The robot in this project is equipped with multiple sensors like IR sensor, ultrasonic sensor. It is capable of follow along predefined black lines and also capable of detect obstacles and avoid it. An android app is used to control the whole thing. Every command is sent to the robot by using the app and then the robot behaves according to the command sent by the app. The app and the robot gets connected to each other via Bluetooth as a Bluetooth module has been used on the robot. Besides, it can be controlled by using infrared remote also because the robot is equipped with infrared receiver also. Overall this project is very interesting and very useful in so many ways. It can be used in industries, hospitals, parks, household application, guidance etc.
