EDGE AVOIDER ROBOT USING I -BOT mini V 3

EDGE AVOIDER USING I-BOT mini V 3 Edge Avoider Robot is built using the IR based Line Detecting Module. The modules are connected in front of the I-BOT so as to detect the edge early and take proper action in time. The distance between the sensors is also maintained greater that the width of the I-BOT considering the turning radius of the wheels. • When the surface is detected the IR module give a high pulse to the controller. • When the edge is detected the IR module does not reflect light thus giving a low pulse to the controller.

BLOCK DIAGRAM An array of sensor is used to detect the edge. Based on the status of sensors, special circuit or controller decides the position of edge and also the required direction of motion required to follow the line. Motor driver circuit is used to ON/OFF the LEFT/RIGHT motors of the robot to provide desired motion.
