This morning I heard about a robotic bricklaying machine called Hadrain built by an Austrailian. It can lay 1000 bricks an hour which works out to about one every four seconds, 24 hours a day, seven days a week. It can build a house in two days. I tried to find a video of it on YouTube and couldn't; however, I did find an article about it in "Tech Times."
The inventor hopes to have it on the market within a year or so. He says it's not to replace workers as much as it is to fill a gap created by not enough people going into the bricklaying profession.
While I'm rambling on about laying brick, I saw a picture not long ago of a machine that lays down the bricks in a herringbone pattern on streets. Bricks are fed into a hopper and they come out on the ground in the pattern on the other end.
