My program for step 17 is still plaguing me, because it won't work with walls of different dimension. I just can't find a way to solve it, but i will eventually.

Sometimes you don't know where someone will put your robot. The program is dependent on knowing this information, so you need to find a way to be certain of your starting position. I found a way to get to a location every time so that the program will work. Still, that's just the beginning.

For some strange reason, I found step 14 easier than step 15. Step 14 is an "unknown" world, so it should be harder. But even so, writing that program was easier than the writing the one for step 15. I didn't really get it, but I'm going to go over it again.

Even though I missed class today, I had someone explain what I missed. My field trip was fun, but it was nothing compared to Computer Programming...:p. To me, algorithms seem like a complex but efficient way of writing programs for unknown worlds. This is helpful, because in real life, we do not always know all the details. A properly written algorithm can get around this problem.

I really get what the tutorial means when it says Python is really picky about code. It's so annoying when I make a mistake, but at least I'm learning to be more careful. I don't really like to do all the checking.

I'm a little confused about the "do" and "while" statements, but it is clearing up bit by bit. Its a bit amusing that Guido keeps "learning" new things. I also have to keep reminding myself to be more and more careful with my codes, because there are more and more potential mistakes.

Now I can shorten the programming code dramatically using the "do" command, which makes the code much more neat and easy to keep track of. I think that its kind of funny that Guido is a robot, but he has parents and wants to dance and all that.

Today I learned that programming shortcuts can be very beneficial and efficient, but it is quite tricky. I kept having to debug my shortcut commands, but I got it eventually. Its kind of difficult, but it is satisfying to get it right.

I am learning how do more things with the Guido program, but the most interesting one is to teach the robot how to do more things. It is kind of complicated, but I'm getting used to being more careful.

Today, I learned many more things, but most importantly, I am starting to understand how the GVR program works. I can now use beepers, turn, and create walls. I am starting to enjoy using the GVR programming.

We learned about worlds, programs, and files today. We used these to control a robot called Guido van Robot. I found it a bit complicated, but I think I understand it better now.

Today, I learned that there are natural and formal languages. People use natural languages for everyday conversations. However, you use formal languages when programming. Natural languages are more ambiguous than formal languages. Formal languages are better suited for programming, because they are very precise and accurate.
