A novel design of line following robot with multifarious function ability

This paper describes the design and implementation of a Line following robot that follows a line which specifically is black line on white surface. This line following robot has two distinguished modes, such as line following mode and obstacle detection mode. It is like a robot car that follows a designated path. This robot can identify obstacles rightward, leftward and in front obstacles while following its designated path on it pathway. So, altogether, it can be said the robot has capability to move following a black line while detecting obstacles three way round. The design includes knowledge of Arduino programming, electrical circuit integration with the designed coding and some architectural as well as basic mechanical engineering knowledge for its development using Arduino Uno. The robot has three sonars connected in three ways round for better obstacle detection and two infrared sensors connection which undergoes with a connection of a motor driver IC (L293D). This follower with multiple modes has given power by a rechargeable lithium battery of 6 volts. All over the robot costs 4500 BDT (Bangladeshi Taka)/4253.15 INR (Indian Rupees), 64.136 USD (United States Dollars). The robot is able to carry up to 600gms of component above while detecting line with identifying obstacles without any problem of changing its course on its designated pathway
