Please help me shortening my code!

Hi guys,
I'm new to all this stuff, but I finally managed to get my code working (after a few days trying). What I ask for you, pros, is to help me shortening my code, so I can learn some more.
Any help improving the code is also welcome! Thanks for all in advance!

Split into new topic.

Most of your code looks like it can be shortened with table lookups and for loops. You can, for example, map all of those letters to lists of turtle moves. You could then just have a general algorithm which goes through the moves and has the turtle move given those inputs.

Indeed I think your code can be shortened.

1. Aren't Sai and Roda the same functions?
2. Could you maybe give a very brief explanation about what the code has to do?

Thanks,
