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 and has a L298 motor driver board for the control of DC motors.

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

The robot uses 2 TCRT5000 sensors in order to detect the white lines and a MZ80 infrared 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 15 mm diameter plexiglass material.

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

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