Obstacle Avoiding Bot

Aim

To make an autonomous basic obstacle avoiding robot.

Hardware used

• 1-Arduino Uno.
• 1-Ultrasonic sensor HC-SR04
• 1-Arduino motor shield
• 1 – External 9v power supply for Arduino as well as motors.
• 2-BO motors
• 1-Caster wheel for support
• 1-Mini breadboard

Details

The obstacle avoiding robot uses ultrasonic sensors for its movements. The ultrasonic sensor is attached in front of the robot.Whenever the robot is going on the desired path the ultrasonic sensor transmits the ultrasonic waves continuously from its sensor head. Whenever an obstacle comes ahead of it the ultrasonic waves are reflected back from an object and that information is passed to the arduino. The arduino controls the motors based on ultrasonic signals.
