Mini Arduino robot moving between lines detecting obstacles moves between the two parallel white lines on a black surface and detects obstacles on its path.

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.

The robot uses 2 TCRT5000 sensors in order to detect the white lines and an IR sensor to detect the obstacles on the path.

When the robot sees an obstacle on its road, it stops and waits until the obstacle is removed.

Robot chassis is prepared with 3 mm thick plexiglass material.

The robot has two 6 V 100 rpm geared DC motors, two wheels and a caster ball wheel.

Mini Arduino robot moving between lines detecting obstacles is powered by a 9 V alkaline battery.
