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.
