24.5. Applications of Cobots in Civil Engineering

Cobots lay bricks with uniform spacing and mortar quantity. Examples: SAM100 (Semi-Automated Mason) used in large-scale projects.

Cobots, or collaborative robots, can automate the process of laying bricks. They ensure that bricks are spaced evenly and that the right amount of mortar is applied. One specific example of this technology in action is the SAM100, a semi-automated masonry machine that has been used in significant construction projects. This technology has the potential to speed up the construction process and improve the consistency and quality of masonry work.

Think of the SAM100 as a very precise chef in a busy kitchen. Just as a chef uses specific tools to ensure that every dish is prepared perfectly and consistently, the SAM100 uses its robotic mechanisms to lay bricks uniformly and efficiently.

Cobots assist in concrete placement, spraying, and smoothing. Integration with 3D printing systems for concrete structures.

Cobots can help in various tasks associated with concrete work, such as placing, spraying, and smoothing concrete. They can also work alongside 3D printing systems that create concrete structures, allowing for innovative designs and construction methods. This integration leads to higher efficiency, consistency in application, and the potential for creating complex shapes that would be difficult to achieve manually.

Imagine a painter using a paint sprayer to apply an even coat of paint to a wall. The cobot works similarly with concrete, ensuring uniform application and helping to achieve a smooth finish without the physical strain that workers would face when performing these tasks manually.

Cobots tie reinforcement bars in repetitive and ergonomically challenging positions.

Cobots can assist in the repetitive and physically demanding task of tying reinforcement bars, commonly known as rebar. This often requires workers to be in awkward positions, which can lead to injury. By using cobots for this task, the physical strain on workers is significantly alleviated, allowing them to perform other tasks that require human oversight or creativity, thus improving workplace ergonomics and productivity.

Think of a rebar tying cobot as a type of assistant that helps a chef with sous-vide — a cooking technique where food is placed in a bag and cooked in a water bath. While the chef focuses on other, more delicate tasks that require human judgment, the assistant takes care of ensuring the rebar is tied quickly and consistently, almost like perfectly preparing the ingredients while the chef manages the larger meal.

Steel structure fabrication with precision welding by cobots. Plasma and laser cutting for prefabricated components.

Cobots are also utilized in welding and cutting processes within civil engineering. They can perform precision welding, which is essential for creating solid and durable steel structures. Additionally, they can employ plasma and laser cutting technologies to craft prefabricated components accurately, speeding up production times and reducing the likelihood of human error.

Imagine a master artist capable of intricate painting details who, instead of using a brush, uses a laser to cut out shapes from metal. This artist, represented by the cobot, can create precise cuts that would be impossible for a human to do consistently, much like how laser cuts in quilting create perfectly shaped pieces to be sewn together.

Cobots mounted with cameras and sensors to scan surfaces, joints, and finishes. AI-based defect recognition for automated reporting.

The inspection and quality control of construction sites can also benefit from cobots. Equipped with cameras and sensors, cobots are capable of scanning surfaces, joints, and finishes for quality checks. They can utilize AI to recognize defects automatically, which allows for quicker identification of issues that need addressing before projects proceed. This not only enhances the overall quality of construction but can help avoid costly revisions later.

Think of a cobot in quality control as a high-tech quality inspector in a factory who never misses a detail. Just as an inspector checks each product for flaws with keen eyes, this cobot employs advanced technology to scan and report issues swiftly, ensuring that everything meets the necessary standards.

Uniform coating and polishing tasks. Reduction of health hazards for human workers.

Cobots can perform tasks related to surface finishing and painting, ensuring that coatings are applied evenly and uniformly. This has the added benefit of reducing health hazards for human workers, especially in tasks that involve toxic chemicals or materials, as cobots can handle these substances with safety protocols in place. Reducing human exposure to harmful substances is a significant advantage in construction environments.

Imagine a skilled painter who is very meticulous about their work. Similar to how this painter ensures every brushstroke is perfect, a cobot takes care of surface finishing, making sure every edge is smooth and every surface is evenly coated without the risks associated with human exposure to chemicals.
