Robots constructing buildings is nothing new. We have covered a bunch of them here in the past. Hadrian X is a truck-mounted robot that can lay up to 1000 bricks an hour using a 30 meter arm. The robot has a hand that grabs and puts the bricks where they belong.
Hadrian X is smart enough to leave spaces for wiring and plumbing. Fastbrick Robotics has more info on this exciting bricklaying machine.
