Robotic arms are mechanical devices that can perform construction tasks accurately, quickly and safely. Robotic arms can function in different ways in house construction, depending on the type of material, shape and design you want to achieve. Here are some of the ways in which robotic arms can be involved in house construction.
– It is possible to assemble complicated geometries using people or robots in situ by fabricating them outdoors such as walls, roofs and stairs. For example, the TECLA project builds a house out of soil and plant fibres using robotic arms and a 3D printer.
– Perform formwork, joining and finishing activities on site materials with flexibility to changing circumstances. Welding, cutting, masonry and concrete distribution are some examples. The In Situ Fabricator project uses a robotic arm to build brick walls of various shapes.
– The robotic arms help employees work more safely and efficiently by performing labour-intensive repetitive operations such as material handling, demolition, drilling and earth moving. In the SAM100 project, for example, a robotic arm is used to apply bricks and mortar on construction sites.
Depending on their complexity and flexibility, robotic arms can work alone or in conjunction with humans or other robots. They may have sensors, cameras, scanners or artificial vision systems to perceive their environment and modify their behaviour. To obtain information and instructions, they can also be connected to computer systems or digital networks. Robotic arms bring benefits to housing construction, such as maximising resources, improving quality, safety, innovation and minimising environmental impact. They face difficulties such as high start-up costs, maintenance, lack of clear standards and potential loss of jobs or human skills.
What are the challenges and limitations of using robots in construction?
Some of the challenges and limitations of using robots in construction are:
– Due to the high initial cost of acquiring, installing and maintaining robots, small and medium-sized companies in the sector may find it difficult to compete.
– Robotic construction environments are dynamic and constantly changing, requiring adaptation of robots, which may require sensors, vision systems and sophisticated planning and control algorithms.
– Lack of clear laws and guidelines on the use of robots in construction, which could lead to uncertainties in terms of liability, safety, privacy and environmental impact.
– The possibility of losing jobs or human skills in the construction sector, which could impact on less skilled workers or those engaged in physical or regular activities. This could indicate the need to train, retrain or retrain professionals in the sector.
These are some of the difficulties and constraints associated with the implementation of robots in the construction sector, but there are also many advantages and possibilities that can compensate for them. Robots can increase productivity, quality, safety and sustainability in construction, as well as encourage originality and creativity in layout and design. In addition, robots can operate in tandem with people, enhancing their strengths and facilitating their task. It is therefore essential to find a balance between the advantages and disadvantages of robots in the construction sector and to encourage communication between the many actors to ensure the ethical and responsible growth of this technology.
How can the costs of using robots in construction be reduced?
The costs of using robots in construction can vary depending on the type, complexity and functionality of the robots, as well as the size, duration and location of the construction site. However, there are some strategies that can help reduce the costs of implementing and operating robots in the construction sector, such as:
– Take advantage of the benefits robots can offer in terms of sustainability, safety, speed and accuracy to save time, money and resources, while avoiding accidents, errors and waste.
– Select robots for construction jobs and projects that can adapt to changing situations and interact with people or other robots in a synchronised and efficient way.
– Analyse the costs and benefits of investing in robots, taking into account all relevant technological, economic, social and environmental factors, as well as potential hazards or pitfalls.
– Seek funding, rewards or support from government or private organisations that encourage the advancement of technology and innovation in the construction sector.
– Developing new skills or competencies to help people in the construction sector integrate into technological change, as well as training and educating them to take advantage of the opportunities presented by robots.
– These are some of the ways in which the costs of using robots in construction can be reduced, but there are also others that may depend on the specific context of each construction site or project.
What are the latest trends or innovations in construction robotics?
With the use of 3D printing technology, specialised and durable buildings and parts can be made from materials such as concrete, metal, wood or plastic. For on-site production and installation, it can be combined with robotic arms or drones. Drones with cameras, sensors, scanners or other instruments can help with transportation, surveying, inspection or other construction-related tasks. By enabling learning, reasoning and adaptability, artificial intelligence (AI) improves the effectiveness and efficiency of construction robots. Machine vision, motion control, path planning and robot cooperation are just some of the robotics-related uses of AI. For example, the In Situ Fabricator project uses a robotic arm with AI capabilities to build brick walls of various designs.
Robotics is a science that studies how to create and control machines that can perform complex and varied tasks. In recent years, robotics has made great progress thanks to the application of new technologies and methods.
