sorry for the delay of my answer.
the project is still in development,but all the real footage has already been shot.
we had a stop due to other commercial jobs and also for waiting the new particle system and the still to come render API, both can solve some of the problems we encountered.
currently the only documentation i’m allowed to publish is the already known pdf http://www.blender.org/community/blender-conference/blender-conference-2006/proceedings/riccardo-covino/ shown at 2006 blender conference and the node compositor feature video http://www.blender.org/features-gallery/features/feature-videos/?video=imaging
when we’ll be ready to publish more pictures/videos we’ll be glad to to do it, but don’t expect anything in the next 2-3 months.
btw, the project is an indipendent short movie and has no government sponsor.
the robot camera currently is safely back in the hands of the owner company, but we hope it’ll be available for further projects
