Mini Arduino obstacle avoiding line follower robot follows white path on a black surface and stops when it detects and obstacle on the road.

The robot is controlled by an Arduino Uno R3.

RS Arduino Uno Shield is used on the robot which contains the input / output headers, on/off switch and a L293D motor driver on it.

3 TCRT5000 sensors are used for tracking the line and infrared sensor module is used for obstacle detection.

Robot chassis is prepared with 3 mm thick plexiglass material.

The robot has two 6 V 150 rpm geared DC motors, two wheels and a caster ball wheel.

Mini Arduino obstacle avoiding line follower robot is powered by a 9 V alkaline battery.
