Hi all, sorry to bother, but I'm trying to have a patrol bot float or hover in one place up and down slowly. I know I wrote a code for it about 5 years ago, modified it from a aum lesson, I think. but I can't find the aum or figure out how I did it. searched for it here on the forum too, but still no answers.

Can someone help me? thanks a bunch!
