I will give you my robot seen here;
http://www.romanblack.com/deskbot.htm

IF you tell us your name and more about yourself.
:o)

His 14 NiCd batteries were bought new but need some
charging now I have kept him charged periodically.
Perfomance of the stepper motors is good and
positioning is quite good, torque is excellent.
It requires a smooth surface, not carpet.

I'll even throw in a "brain" for him with a new
16F628.
