Obstacle Avoider Line Follower Robot
   
MINI LINE FOLLOWER ROBOT WITH MZ80 INFRARED SENSOR
Mini Line Follower Robot With MZ80 Infrared Sensor

Mini line follower robot tracks the white path on a black surface. When the robot detects any obstacle on the path, it stops and waits until the obstacle is removed. Then, it continues to follow the line.

The robot uses 4 CNY70 sensors in order to track the line. 74HC14 Schmitt triger was used for the sensor circuit.

There is an MZ80 infrared sensors on the robot, which was used to detect the obstacles on the path.

The robot has a compact design with two N20 geared dc motors connected to 2 wheels, and a caster ball wheel.

Video of the robot

The robot was powered by a 9 V alkaline battery.

PIC16F628A was used as microcontroller for the robot.

L293 motor driver was used for the driving of the DC motors.
