LINE SENSING AND OBSTACLE DETECTION ROBOT

The main aim of this Project is to design a Robot which is capable of following

line using line detection sensor and ultrasonic sensor for obstacle detection and it

automatically stops when there is no line available in its presence.

In our project we are using line detection sensor to detect the Line detection

sensor to detect the line. This Robot automatically senses the presence of obstacles in its

path and changes its direction of movement. The obstacle detection mechanism is done

by an ultrasonic sensor that makes uses of ultrasonic waves to find the presence of an

obstacle in its path. The Microcontroller receives the Infrared Signal from the receiver

and it decodes and performs appropriate Action. The Range of the system is up to 10

meters.

Ultrasonic sensor has transmitter and receiver. Micro controller will generate the

40 KHz transmission signal. The receiver will receive the signal which is reflected from

the surface of the object. The return signal is amplified. The microcontroller is then used

to calculate the time of flight (TOF) for the sound wave that is bounced off of distant

objects. Using this device we can measure the distance of 10cm to 400cm.

The controlling device of the whole unit is a Microcontroller to which input and

output modules are interfaced. The Microcontroller is programmed in Embedded C

language which intelligently performs the specific task. Here, the Microcontroller gets

input from the line sensor attached to the robot. This input is processed by controller and

acts appropriately on the motors of the Robot. The system also uses ultrasonic sensor for

obstacle detection.
