Hi Nicolas, I tried what you said but I still get some repeatedly import
errors as the messages below:

ImportError: No module named middleware.yarp
Python script error from controller "object_pick#CONTR#4":
Traceback (most recent call last):
  File "object_pick", line 4, in <module>
AttributeError: 'module' object has no attribute 'selectedObject'
Python script error from controller "object_pick#CONTR#4":

Python script error from controller "check_visibility#CONTR#5":

  File "check_visibility", line 4, in <module>


I was looking for middleware.yarp but I didn't find it yet. Another issue is
why I can't edit Yarp_python_simulator.blend file. I mean I tried to change
some pieces of code but It's not allowed to change anything. Do you have any
idea about it? My python is 2.5.

Thanks agaiin
