26.1. Bricklaying: SAM100 by Construction Robotics (USA)

The Semi-Automated Mason (SAM100) is a collaborative robotic system developed by Construction Robotics to assist with bricklaying. It does not fully automate the process but works alongside human masons.

The SAM100 is a robotic tool designed to help humans with bricklaying tasks rather than replace them. This means that instead of doing everything by itself, the robot works in tandem with skilled masonry workers. This collaboration allows for a better blend of human intuition and robotic efficiency, making the whole process faster and more precise without compromising on the quality that human masons provide.

Think of the SAM100 as a very skilled assistant in a kitchen. Just like a chef who has a sous-chef, the robot does the heavy lifting (like getting the ingredients) while the chef focuses on assembling the dish perfectly. This combination leads to faster meal prep times while maintaining high culinary standards.

• Humans handle setup, alignment, detail work, and quality assurance. • Robot performs repetitive and high-effort tasks like picking bricks, applying mortar, and placing them with precision.

In the collaboration between the SAM100 and human masons, there is a clear division of responsibilities. Humans are responsible for critical aspects of bricklaying such as setting up the work area, ensuring each brick is in the correct position, and checking the quality of the work. Meanwhile, the SAM100 takes on the repetitive and physically demanding tasks such as fetching bricks from a pile, applying mortar accurately, and positioning the bricks correctly. This allows human workers to focus on more skilled tasks while reducing their physical strain.

Imagine a sports team where a player specializes in defense while another focuses on scoring. The defender safeguards the goal, ensuring no opponent can easily make a move, while the striker is free to aim for the goal without worrying about the defensive side. This specialized teamwork maximizes their strengths and enhances overall performance.

• Used in multiple projects across the US, including the Berkeley Building, New York. • Achieved 3–5 times faster bricklaying speed.

The SAM100 has been implemented in various construction projects throughout the United States, one notable instance being the Berkeley Building in New York. Its use has significantly increased the speed at which bricks are laid—by a factor of 3 to 5 times faster than traditional methods. This speed increase is crucial in meeting tight construction deadlines and managing costs effectively.

Consider the difference between a traditional bicycle and a high-speed racing bike. While both can get you to the same destination, the racing bike allows you to reach that point much quicker due to its design and engineering. Similarly, the SAM100 is like the racing bike for bricklaying, allowing construction projects to progress at a much faster pace.

• Reduced physical strain on masons. • Enhanced consistency in brick placement. • Optimized use of skilled labor for critical detailing.

The implementation of SAM100 has resulted in several positive outcomes. First, it reduces the physical effort required from masons, leading to less fatigue and the potential for fewer injuries. Second, by performing repetitive tasks, the robot ensures that each brick is placed with high precision, which improves the overall quality and consistency of the masonry work. Finally, with the robot handling labor-intensive tasks, human masons can devote their skills to more intricate detailing that requires human judgment, thereby optimizing the overall labor force use.

Think about how using a dishwasher reduces the amount of time you spend washing dishes by hand. With less time spent on the mundane task, you can instead focus on preparing more delicious meals or engaging with guests. In the same way, SAM100 takes on the more draining aspects of bricklaying so skilled masons can concentrate on creative and detailed work.
