A more complex example is the Apple Pie bakery shown below. I want to have four sets of bots that make pastries, raw apple pies, and the apple pies. I found that when I first built the bakery and directed the raw apple pie making bots (wearing the top hats) to put the apples and the pastries onto their own kitchen tables, they would sometime run off to another area to get the apples and the pastries that were not the nearest to their tables. So, I added a beacon with a very small range near each of the tables. Now, the bots no longer waste time running to the wrong apples and pastries.
