Construction projects are time-consuming, labor-intensive, prone to delays, disputes and other issues. Robots on the work sites make many of these problems go away.
A robotic bricklayer named SAM, which stands for semi-automated mason, has started working alongside some construction workers, the MIT Technology Review reported last year, applying mortar and laying brick. A human worker is still needed for the tasks that require a little more finesse, such as handling aesthetic details or working on corners. SAM can lay bricks three times faster than a mason doing it the old-fashioned, however.
Another robot, named Hadrian, developed by engineers in Perth, Australia, can take that even further, working 20 faster than a human bricklayer, Gizmag reported last year. Hadrian is capable of laying up to 1,000 bricks per hour and can lay down the framework of an entire house in two days.
