LINE FOLLOWING ROBOT WITH FAULT TOLERANCE

SCHEMATICS : ( MADE IN PROTEUS ISIS )

5 SENSOR LINE FOLLOWING ROBOT USING DIFFERENTIAL DRIVE

WORKING:


1. FULL WHITE SURFACE : CONTINUE ITS PATH
2. BLACK STRIP BELOW THREE MIDDLE SENSORS: FOLLOW THE BLACK STRIP
3. BLACK STRIP BELOW TWO SENSORS ( IN- LINE ) : ONE WHEEL FUNCTIONAL
4. BLACK STRIP BELOW ONE SENSOR ( IN - LINE ) :  DIFFERENTIAL DRIVE
5. BLACK STRIP BELOW EVERY SENSOR : CONTINUE THE PATH
6. BLACK STRIP ABSENT AND WHITE SURFACE AHEAD : CONTINUE THE PATH TILL
    BLACK STRIP IS UNDER THE THREE MIDDLE SENSORS
7. FOR SHARP TURNS THE TWO EXTREME SENSORS ARE USED.
8. SHARP TURN RIGHT HANDLED USING RIGHT EXTREME SENSOR AND ROBOT MOVES RIGHT
9. SHARP TURN LEFT HANDLED USING LEFT EXTREME SENSOR AND ROBOT MOVES LEFT
