14.11. Human-Robot Collaboration (HRC) in Construction

Human-Robot Collaboration (HRC) refers to the shared workspace and task execution between humans and robots. In construction, this collaboration allows robots to augment human capabilities rather than replace them.

Human-Robot Collaboration (HRC) focuses on how humans and robots can effectively work together in the construction industry. Instead of robots taking over jobs entirely, they complement human efforts, enhancing productivity and safety. The robots assist in tasks, allowing workers to leverage their unique skills in coordination with robotic capabilities. This forms a partnership where both robots and humans play essential roles in completing construction tasks.

Imagine a construction site where a human operator uses a robotic arm to lift heavy materials. Instead of trying to lift a heavy beam alone and risking injury, the worker controls the robotic arm remotely. This allows the worker to handle the heavy load safely while focusing on the precise placement, showing how robots can enhance human strength without taking over the job.

• Coexistence: Humans and robots work in adjacent zones without direct interaction. • Sequential Collaboration: Humans and robots work on the same task but at different times. • Cooperation: Humans and robots perform different subtasks simultaneously. • Collaboration: Humans and robots work together on the same task in real-time.

There are several types of interaction between humans and robots in construction: 1) Coexistence means they operate in separate areas of the site. 2) Sequential Collaboration occurs when humans and robots handle different shifts of the same task. 3) Cooperation involves both working at the same time but on different parts of a task. 4) Collaboration is when both actively work together, sharing tasks and responsibilities. Each type has its own benefits, making understanding the context of the interaction essential for optimizing construction processes.

Think of a kitchen where a chef (human) and a food processor (robot) work together. In a coexistence scenario, the chef slices vegetables while the food processor chops herbs nearby without interfering. In sequential collaboration, the chef might prepare the ingredients while the food processor makes a sauce afterwards. In cooperation, while the chef cooks chicken, the robot simultaneously stirs a pot of soup. Lastly, in collaboration, the chef might pour ingredients into the food processor as it mixes, proving they can work in tandem effectively.

• Proximity Sensors and Vision Systems • Wearables and Gesture Recognition • Augmented Reality (AR)-based Interfaces for robot programming and coordination • Force Feedback Systems for real-time adaptation

Safety and interface technologies are critical in ensuring effective collaboration between humans and robots. Proximity sensors help robots detect nearby humans to avoid accidents, while vision systems allow them to interpret their surroundings. Wearables and gesture recognition enable workers to control robots through movements or devices. Augmented Reality can display information about the robot's tasks directly in the worker's view, facilitating coordination. Force feedback systems help robots respond to human actions in real-time, adapting their movements to ensure safety and efficiency.

Imagine a warehouse where workers use smart gloves that can communicate with robots. These gloves may have sensors that allow the wearer to guide a robot arm to pick up or move items simply by pointing. If a worker approaches a robot, the proximity sensors stop the robot from moving, preventing accidents. This is similar to how a driver uses tools in a vehicle, like sensors that alert them of obstacles when backing up, ensuring safety.
