LINE FOLLOWER USIG STEPPER MOTORS
You can use a stepper for good accuracy and speed, but the problem with torque. I have seen some students working with steppers in the 'Printer'. But the problem of high power supply. You should use L298 with heat sink and a good power supply. The torque problem is a great headache. So your
robot won't be moving so fast as you required even though your logic is good. So if you are going for steppers in line followers you should go for a small stepper and the power supply should be of small battery, stepper of good torque and speed. Then you can win the race. But the cost will increase drastically because we mostly use two 9V battery costing Rs.15 each for most robots, but getting good batteries of low size is a costly affair. The the second thing is the cost of stepper you are using, it will be going above Rs.500.
