2. Introduction
 Collision Avoidance (CA) systems have been used in wide range of different
robotics areas and had extra ordinary success in minimizing the risk of collisions.
 It is a critical requirement in building mobile robot systems where they all featured
some kind of obstacle detection techniques in order to avoid two or more objects
from colliding.

3. Introduction
 The purpose of this paper is to present an algorithm for performing collision
avoidance in mobile robot that is relying on the use of low-cost ultrasonic with
infrared sensors, and involving some other modules, so that it can be easily used in
real-time robotic applications.
 The proposed algorithm is implemented in multiple scenarios with several
obstacles placed in different locations around the robot.
 Our experimental run shows that the robot has been successfully detecting
obstacles and avoiding collisions along its path.

4. Block Diagram
 The following figure shows the block diagram. The system consists of ultrasonic
sensor, Arduino UNO board and Motor driver.

5. Block Diagram
 The above diagram is the functional block diagram of the entire system.
 The main controller will trigger the Servo Controller, receive the distance values,
run the collision avoidance algorithm and control the Stepper motors.
 The Servo Controller controls the ultrasonic sensor and servo motor while
providing the readings from the ultrasonic sensor to the main controller.

6. The working of the system
 The ultrasonic sensor will detect when an obstacle comes in front of moving
robot and it will stop without colliding with any obstacles that may exist in its
path.
