The document outlines the design and components of a line-following robot equipped with obstacle avoidance capabilities. It details the use of an Arduino Uno microcontroller, motor driver, ultrasonic and IR sensors, and a servo motor to navigate a path and circumvent obstacles. Applications for the robot include industrial goods handling and waste transportation in mining sites.

1. Line Following
Car with Obstacle
Avoidance

2. What is the Aim?

3. What is the Aim?
The aim is to ensure that the robot follows a
line without deviating and move around an
obstacle if detected and return back to
the line

4. Materials
Required

5. Arduino Uno Board
• It is a Microcontroller Board (Mini CPU).
• It can able to Store about 32KB of memory.
• It is programmed and used for various
projects.
• It is programmed by the Arduino Software.

6. Motor Driver L298
• It receives comments from Arduino UNO.
• It controls the speed of the motors.
• It also used for rotate the model.

7. Ultrasonic Sensor
• It emits sound waves to find the distance
• The frequency of the sound wave is above
the hearing level of human

8. IR Sensor and Receiver
• It emits light to sense the object.
• It contains two parts – one send the light
source and another receives the light

9. Servo Motor
• It is used to rotate the Ultrasonic Sensor.
• It will rotate at the fixed angle, which is
coded on Arduino UNO.

10. And Motors, Wheels, and Some
Jumper wires

11. Working Process
The Line following robot detects the
a path, and drive through it.
It follows the path with the help of IR
Sensor attached to it.

12. • If any object is placed on the
path, by using ultrasonic sensor,
the line follower can detect the
obstacle and change the path to
cross the object and return to
the same path.

13. Uses
•It can be used in the industry sites to handle the
goods
•In Mining sites, this can used for carry the waste
soil or other things
•So on..
