Not exactly the type of self-constructed architecture described by Bruce Sterling in "Distraction" but very close: R-O-B by Gramazio and Kohler from ETH Zürich:

"R-O-B extends the traditional prefabrication process of construction: the robot leaves the protected environment of the production hall and ventures out to the building site. Housed in a modified freight container, the R-O-B mobile fabrication unit can be used anywhere in the world. It combines the advantages of prefabrication – precision and consistent high quality – with the advantages of short transport routes and just-in-time production on the building site. Furthermore, the mobile fabrication unit is not restricted to a predefined manufacturing process or a particular building material. Making use of computer methodologies in the design and fabrication process allows for manufacturing building elements with highly specific forms, which could not be build manually."

Why do I blog this? curiosity towards the application of robotics in architecture. The thing recently participated in the construction of this Wall presented at the Venice Biennale
