If you need some inspiration from 30 years ago :-) http://www.technicopedia.com/8094.html

Edit: My brother owns that set, I am a few years younger and got to play with all his LEGO. Great times.

I hqve one of these sets too (plus other technic from the same era) it’s still functional. Fond memories.

One of the out-of-the-box robots have pen plotting capabilities already, so it would be easy to modify and extend the code.
