I had to change code at 4 or 5 positions in the already existing file robot_functions.
so, the easiest way is to replaceing this file (if you didnt made some changes in this file yourself, else make a backup!).
In the header of the file, I have listened all changes, i made.
The english part of it in my homepage will comming soon...
(Or has anyone desire for doing that?)
sorry for my bad english
