    INTRODUCTION

    Line follower robot using microcontroler

    A line follower is basically a machine designed to follow a path predetermined bythe user. The path maybe as simple as a straight or a curved line or it maybe as

    complex as a 90 degree turn and junction counting capabilities. In our semester

    project, we will concentrate on simple tasks.

    Line follower robot can detect bright light using specific sensors, and de fine its

    motion accordingly. Line follower senses the line using its sensors and

    maneuvers the mechanical structure to stay on course while constantly correcting

    wrong moves.

    The correct positioning of the sensors presents a feasible controlling strategy for

    complex as well as simple tasks. A robot will know when to turn depending on the

    location of the sensors. Number of sensors determines the smooth movement of

    the robot. Optimum distance between the sensors depends on number of sensors,

    width of straight line and the logic applied

    CIRCUIT DESCRIPTION OF LINE FOLLOWER

    ROBOT

    This line follower robot is design by basic microcontroller (8051). Microcontroller

    is the heart of the embedded design. Output is obtained from port1 at which

    7segmnt is connected and port2.4, 2.5, 2.6, 2.7 at which DC motor IC(L293D) is

    connected as shown in circuit diagram. To play this remote control vehicle switch

    swf , swb,sws are placed in on position (or pushed) port3. But when we press

    switch swf motor will move in forward direction and when switch swb is pressed

    motor will move in reverse direction otherwise when sws is pressed it is in stop

    condition. when we press switch swf then F is display on 7segment or when we press switch swb then B is display on 7segment or when switch sws is pressed

    then S is display on the 7segment.
