Repetitive construction robots have become more popular for small to large masonry contractors alike.
A housing project in Illinois is the first construction project in the USA to use both MULE (Material Unit Lift Enhancer) and SAM (Semiautomated Mason) robot technology. The 166,000-sf barracks contains 300 bedrooms for 600 military personnel is under construction at the Great Lakes Naval Base and is being constructed with the help of robots which can place foundation blocks weighing up to 135 lbs and lay bricks every seven to 10 seconds.
This $52 million project, started last March and scheduled for completion in October 2020.
There are currently more than 130 MULEs operating in the field, and 11 SAMs across the contractors in North America with more under operation.
