Fast Obstacle Avoider Line Follower Robot
line follower robot

This is a basic line follower robot tracks the white path on a black surface.

The robot uses 3 CNY70 sensors in order to track the line. 74HC14 Schmitt triger was used for the sensor circuit.

It has two 6 V geared DC motors, two wheels and a caster ball wheel.

Basic line follower robot was designed as simple as possible, it is good for starting to deal with robotics.

Video of the Robot

The robot was powered by 3 AA alkaline batteries.

PIC16F628A was used as microcontroller for the robot.

Two BDX53 darlington transistors were used for the driving of the DC motors.
