[Robotics] robotics example

[Nicolas Lassabe]

Hi Breno,

Did you copy the yarp.py and _yarp.so ? Do you have the same version of python to run blender and for yarp-python ? It should be python 2.5 or 2.6.

$ sudo cp yarp.py /usr/lib/python2.5/site-package/
$ sudo cp _yarp.so /usr/lib/python2.5/site-package/_yarp.so
