Robot that 'Draws' in 3D

From the project page:

"MATAERIAL is the result of the collaborative research between Petr Novikov, Saša Jokić from the Institute for Advanced Architecture of Catalonia (IAAC) and Joris Laarman Studio. IAAC tutors representing Open Thesis Fabrication Program provided their advice and professional expertise. During the course of the research we developed a brand new digital fabrication method and a working prototype that can open a door to a number of practical applications. The method that we call Anti·gravity Object Modeling has a Patent-Pending status."
