"Michigan, 20 masons lay bricks for a huge dorm, as big as three football fields, at the Naval Station Great Lakes in Illinois. Compared with those in years past, these workers are doing far less laying and “buttering” and, instead, are focused on quality and on cleaning up mortar joints.
.
A robot named SAM handles the real grunt work.
.
SAM, a clawlike metal arm extending from a cage, moves back and forth along the walls, buttering and layering a brick every eight to 12 seconds. Nearby, another robot called MULE uses a burly 12-foot arm to lift heavy cement blocks for workers, who then guide them into place.
.
Neither bot takes sick days or gets sore muscles, and both can work around the clock.

These days, reliability is a big issue in the construction industry, responsible for nearly $10 trillion in global spending annually. The vast majority of large construction projects go over budget and take 20% longer than expected, according to consulting firm McKinsey.
.
The problem is partly owing to a labor shortage.
...
Ekso Bionics makes robotic vests that support a worker’s arms for jobs like drilling or installing piping overhead. It also sells a robotic arm that makes it easier for workers to use heavy tools, reducing fatigue and injury.
.
And Dusty Robotics makes small autonomous bots that roll around construction sites and mark lines on concrete floors that indicate the location of walls and infrastructure, based on construction documents.
.
Few companies are trying anything as ambitious as San Francisco startup Built Robotics. It sells autonomous technology for bulldozers and other heavy equipment. The tech can enable a Caterpillar tractor, among others, to move dirt and lift pallets of wood—all without anyone in the cab."
