How robots can take the building industry to the next level
Published on 29.07.2021
Robots get hands-on
Single-task construction robots (STCRs) can be found on sites completing repetitive tasks, such as bricklaying, welding, or concrete laying. Additionally, autonomous driverless trucks are used to transport materials. These types of robotic equipment often use digital logistics-driven control technology equipped with sensors to detect humans and obstacles.
Equipment can also be remotely controlled or programmed. For example, drones are increasingly being automated to complete large-scale, exterior painting projects.
Hand in hand with robots
Like in a factory, construction robots often work in a hybrid environment, meaning side-by-side with human workers. Robotic machinery boosts overall productivity on the site without replacing actual workers. By implementing robotics on-site, workers avoid overexertion and repetitive stress injuries, leading to less employee turnover.
Currently, the industry is even exploring the possibility of literally merging robots and humans – with an exoskeleton. These are rigid or soft wearable robotic elements that extend human strength and capacities. In the future, these elements could even collect and analyze data and use machine learning to detect how to better support the wearer in real-time.
Robots: an extra set of eyes and ears
Urban construction sites require constant monitoring and managing. To help orchestrate hybrid locations where robotic heavy machinery and humans work together, smart robots such as aerial drones or on-the-ground scanners can make a huge difference.
For example, LiDAR (Light Detection and Ranging) equipment can be used to scan and gather information at a worksite. Combined with AI, the equipment can detect problems and suggest the next steps. It can also create real-time 3D models of a site, helping supervisors calculate updates on work rates, productivity, and costs. 3D models will also be essential in helping manage and oversee the various automated machines at work on the site.
An additional and essential aspect of surveillance is the inspection of dangerous environments. Drones are increasingly utilized to carry out fire and safety inspections.
Robot-made building components
In the future, robots will be responsible for making components or even entire sections of buildings. 3D printing or additive manufacturing is now being employed on- and off-site to create components, but also in repair work or for the reproduction of historic elements when restoring old buildings.
The use of large-scale prefabrication (LSP) approaches is also being explored. Modules, such as for bathrooms or kitchens, will increasingly be made by robots in the future in the factory and then assembled on-site.
Both 3D and pre-fabricated approaches have the added advantage in that they only use the exact amount of material needed for a component or module, cutting down on waste and thus creating a more sustainable building.
Robots forging new paths
The use of robots can also significantly improve services in building maintenance. A TK Elevator pilot project explores the use of driverless vehicles to deliver materials to repair sites. Potentially, a cloud-based system could form a complete logistics network that can save technicians time as well more efficiently manage the distribution of spare parts.
Robots can be trained to “walk” in our footsteps. A “follow-me” smart technology has been developed by Piaggio Fast Forward (PFF) which improves a robot’s ability to sense direction and velocity and allows humans to control the robot via pairing.1 Cargo robots carrying up to 40 pounds of cargo, such as the “Gita”2, could accompany technicians, carrying spare parts and tools and eliminating the need for vehicles.
When this PFFtag technology is paired with GNSS (Global Navigation Satellite System)3 sensors it can be integrated into all types of on-site machines. Testing has already been conducted on the “Spot”4 robot. When fully tested, the technology can be used in construction, building maintenance, and logistics industries, enabling collaborative, intuitive robots that can follow and assist construction workers in a variety of tasks.
Opening the doors to robots
Hospitals, warehouses and supply centers, and hotels are increasingly implementing robots to improve services and customer care. However, for robots to be able to work autonomously, they need to be able to move through a site or building independently – even on elevators or industrial lifts.
TK Elevator has now developed a robotics interface platform that enables robots to use elevators and thus move freely through, and up and down, a building. The interface allows robots to communicate via WiFi or 4G LTE with elevators and make floor selections like a human passenger.
Relying on robots
Until now, the changes in the construction industry have been gradual. However, as the industry sees the rapid changes that come with the adoption of advanced technologies like robots, it will soon be no holds barred. Working with robots, buildings will benefit from the new speed and efficiency that will certainly result in yet another wave of innovation in design and sustainability.
