Bricklaying robot twice as fast as humans

please link to this story about another robot bricklayer: http://www.domain.com.au/news/worldfirst-robot-brickie-hadrian-can-build-a-house-in-two-days-20150714-giaw96/ The comparison with human bricky was taken from a few discussion threads that we can't cite in the story but they are all giving similar numbers, so OK to assume 500-700 a day

A US-based company, Construction Robotics, has created a brick-laying robot called the semi-automated mason or SAM which can lay 500 to 700 bricks per day. The robot has been in use for a few years but came to public prominence when a gif of the robot became viral. As we previously reported in July 2015, Perth-based company Fastbrick Robotics was developing a robot called “Hadrian” that could lay 1,000 bricks per hour. The robot had the potential to erect the brick frame of a house in just two days, rather than in weeks. Over AUD$7m was spent on the 10 year project.
