Hey All,

I'm trying to finish up my Wall-E build.

I have the track/motors, arms, sonar all done.

Trying to tackle the head. All I want is simple left/right
and up/down.

I've been browsing the forum and looking at as many
builds but haven't got a clear picture of how people
are doing this.

I can do the left/right easily, it's the up/down that I'm
not sure how to carve in.

I could use a helping/guiding hand please.
