Rajesh--

Nearly any microcontroller will do the job, so you should choose one
that you have easy access to and is popular so you can get good tools
for it. The PIC chips are a fine choice. (The Atmel AVR line is my
favorite ... probably because I have a mess of 'em.)

Since you're doing the building of the robot, you could even build the
programmer & such. Do a google search on PIC and you'll find plenty
of schematics for controllers and stepper motor controllers for you to
build. If you're only interested in building the mechanical parts,
I'm certain you could find reasonably priced electronic modules to do
the job for you.

By the way, you should change the subject line when you're asking an
unrelated question, so people will know what's going on.
