Hi everyone, I need help regarding my automatic guided vehicle which I
intent to work on as my final year project.

What I have selected so far.
8051 as MCU
2 stepper motors for differential speeds while turning and keep them
synchronized while in linear motion.
Sensors for path control.
A PIC16F84 and two L293D H-bridge drivers for bipolar steppers.

What I need is path control mechanism ( detection of obstruction and
movement from one point to other including turns and to compensate the
slip etc)

Also need help on sensors - what kind of?

Any help is greatly appreciated, please share your thoughts and ideas.
Thanks.
