No, there isn't. But DrawRob should exist. I knowDrawRobPer exists.
Looked at your code, I'm really impressed. Only things I'd recommend:
1. Indenting. It's a style thing only, has no effect on the code, but it makes it more readable. Look at Darwinbots' code for examples of when you would indent or unindent.
2. You would be better off grouping code into their own Subfunctions, that themselves call smaller syub functions, etc.
So that your main code would look like:
Setup
Do
CheckInput
UpdateGraph
loop while blah blah...
Like that, it makes the program look more professional. In the end, you'll have a tree of functions, that all call smaller functions, that call smaller functions, etc.
