displacement or position sensors (6 to 10 cm)

position sensors as in "what position is the base of the arm in?" ? I'm
sorry, I don't understand what you're asking exactly and besides having a few
possible suggestions, I'm curious to see what answers pop up here on the
newsgroup as well.
If it's for distance, probably a mouse wheel sensor might be easiest.
Ridiculously small but not necessarily that hard to use. That's a very small
robot you're building. What about just painting the wheels with a white stripe
on half the wheel, then detect the white stripe with a reflective pair LED /
phototransistor? How accurate would you need to be?

Well if you look in any electronics catalogue for a 'displacement'
transducer, you'll get a thing that looks a little like a mini hydraulic
ram, that gives an electrical output proportional to the position (or
displacement) of the 'piston.
Farnell or RS do quite a few
