This photo was taken at the Bartlett School of Architecture London back in April at the FABRICATE 2011 Conference. During an intermission near the coffee and small muffins this installation / demonstration was displaying Gramazio & Kohler's research and work toward extending the prefabrication process of construction into the field. Here exhibiting the robot's ability to judge which “brick” to lay next via coded instructions and physical analysations (previous / next / available blocks).
I am only reminded of this due to my current academic project having birthed a large mechanical arm docking “pod” hotel rooms from traveling about the Bavarian mountain side. Gramazio & Kohler’s execution seems to be more elegant though.
