Robot arm help?

A while back i saw an instructable that was a wooden robot arm it had a main arm and a second smaller one. the smaller one had a handle that allowed you to move it. you moved the smaller arm to program the larger one. anybody know what i am talking about?

i wish i could explain it better it had a small arm that would track its movement then the larger arm performed it
Analog or digital?

You're looking for a pantograph. It appears that there are several I'bles on the subject.
