Build automatic elevating platform?

Hey, didn't know if anyone could help with this:

I need to build a motorized platform for my tripod, that would automatically raise
and lower itself, so I can get different vantage points as the motorized tripod
head will pan or tilt. What's the easiest way for me to do this?

Thanks for the help in advance!

Look at 3D printer and CNC projects at how they use a stepper and screw to raise and lower the z axis.
