Can anyone give me more details on using H bridge for driving the motors? I don't want to use any ready-made ICs. I want to build my own H-bridge. I am using LDR sensors to detect a white line and hoping to connect it to the H bridge.
Other questions:
1. Can H-bridge be used to stop one motor, while the other one continues to rotate so that the robot, as a whole, turns as the white line curves?
2. How do we control the speed of the motor connected to the H-bridge?

the problem with h bridges is that u have to make a single hbridge for each motor...and why don tu want to use premade ic's /...they are pretty useful and really help...why do u want to go through the tedious job of making one urself

You can build your own (rather than from a shop). Check out my tutorial in the members pages - I give various circuits.
You need an H bridge for each motor
You control the speed using PWM.
