Concatenating strings #1
Conversation
For me, the IDE couldn't concatenate the int types with strings. So I had to create 3 strings and concatenate them.

First off, thanks for contributing. However, your problem seems strange. Have a look at the official Arduino Reference for the object String this clearly states that adding integers is allowed and should work since version 0019 (which is a long time ago). My IDE certainly does not complain, so maybe something else is wrong... |

I don't like the style here. There is really no reason to make three String objects and concatenate them in a String constructor.
If concatenation of integers in strings does not work, why not just change line 38 to:
report = String(i) + String(": ") + String(pos)

The syntax is obviously amateur. My point was that it couldn't concatenate the int types with the string ": ". I also found this site. If you scroll a bit down it actually explains the same scenario of concatenation. It says "This won't compile because the compiler doesn't handle the operator precedence correctly." I use the 1.0.6 version for the Crustcrawler.
Anyway, I just changed the code on my computer. If you say it works for you than something must be wrong on my side, but I wrote the code line by line and the only time it couldn't compile was when I tried to create the report string.

One more thing, I might have mislead you. The IDE can compile, but if I upload the code to the robot and open the serial monitor with the original code I only get a bunch of ones. Nothing else. However changing the code seemed to work.
