[Robotics] robotics example

[Gilberto Echeverria]

Hi Breno,

I just tried to find out what could be the problem, and honestly I 
couldn't make that code work myself. The blender file you are using is a 
bit outdated now, since we have made lots of changes to the whole 
framework. Our yarp-blender bindings have changed a lot, and so, they 
don't work anymore with this file.

Can you try downloading the latest files from:
https://code.launchpad.net/~blender-for-robotics/openrobots-simulator/ors
To install, the instructions are in:
https://answers.launchpad.net/openrobots-simulator/+faq/844

Let us know if you have any problems installing or running this code.
All the best.

Gilberto
