Question about Velleman Allbot VR408

"fatal error: ALLBOT.h: No such file or directory" is probably the relevant error here.
This is a C library that you are missing.
https://github.com/Velleman... <-- Here you can find the current version.
https://www.arduino.cc/en... <-- Here are the instructions for installing new libraries.
I don't have an Allbot, so I can't speak from experience.
But try it with this and maybe it will help.

Maybe he doesn't like your folder name with the "for"... Please use a file path without umlauts and spaces. Otherwise, contact the manufacturer to find out what the problem is.
