h-bridge schematics

H-Bridge is a must used for your robot to control the motors… the speed and the direction of each motor. There are many kinds of H-Bridge. For low current DC motor, you can use IC L293D or L298N to drive your motor.

H bridge is an electronic circuit that enables a voltage to be applied across a load in either direction. These circuits are often used in robotics and other applications to allow DC motors to run forwards and backwards. H bridges are available as integrated circuits, or can be built from discrete components.

line follower robot without microcontroller

Another Line Follower Robot without microcontroller project. This project built using IC timer 555 to generated PWM signal to make the motor running smoothly. This Line Follower Robot tutorial written by Jaseung Ku – 17 Dec 2005. May be this is “not professional” robot, but i think it so cool to create a robot simple things around your place.
