The newly formed bricks looks a bit like a Lego blocks and stack the same way, overlapping and connecting with the pegs and the holes. In theory, the newly formed brick provides similar structural stability with less material. If only a machine like this already existed — it would be perfect to help in the reconstruction of Haiti after the earthquake. Companies should already be working in Haiti to recycle the debris in order to rebuild, but with this robot they could rebuild even quicker.
