A New York-based company has invented a semi-automated robot that is able to lay bricks up to six times faster than a human can. The Semi-Automated Mason (SAM) system costs $500,000 (£330,000) and has taken New York-based Construction Robotics eight years to develop and test out on construction sites.
The system is available to order and features a robotic arm that is able to pick up bricks, apply mortar and then lay each brick in the desired location to build up a wall, laying between 800 to 1,200 bricks a day. In comparison, a human mason can only lay about 300 to 500 bricks a day.
The robot can be mounted on scaffolding and is even clever enough to adjust for wind swaying the structure it is standing on, as well as to figure out the difference between the building's planned specifications and what's actually on site.
Robot saves heavy lifting, but still needs plenty of human direction.
As its name suggests, the robot is not completely automated – a human needs to follow it and tidy up after it or carry out more intricate tasks such as laying corner bricks, so it will not be replacing anyone's job any time soon, while humans are also needed to run a control panel on a tablet that sends specific commands wirelessly to the arm.
What makes the robot useful, though, is the fact that it can save a great deal of lifting. It is also able to perform a wide array of functions due to computer algorithms, sensors that measure velocity, orientation and angles, and a laser that acts as the robot's eyes to sense depths and distance.
To that end, SAM can be programmed to create different types of brick bonds, or extremely complex patterns using different coloured bricks. It can also stamp a brick with a particular company's logo by following a digitised pixel version of an image, or bump bricks in or out of the wall by half an inch in order to create a textured appearance.
Robot unlikely to replace humans on the building site
SAM comes with a control panel on a tablet that lets humans input specific measurements on site that are sent wirelessly to the robot.
According to Construction Robotics, in recent years a shortage in masons has led to the price of bricklaying increasing sharply. SAM can help with this since it can speed up the building of long stretches of wall, but when it comes to short stretches, it would still be more effective to use a mason and humans will still need to perform quality control on the robot's work.
"Your mason monitors wall quality, while SAM does the heavy lifting. Masons that haven't worked with SAM are hesitant at first, but once they learn and work with the robot they, and realise it won't take their job, they are very open to it," Zachary Podkaminer, operations manager at Construction Robotics, told Construction Manager.
To get SAM to work, masons first need to use Construction Robotics' proprietary software to design how they want their wall to look.
