Construction robotics: Building the future

The construction industry, a cornerstone of economic development, stands on the cusp of a technological revolution. While sectors like manufacturing and logistics have long embraced automation, construction has traditionally been more reliant on manual labor.

However, the tide is turning. A new wave of innovation is bringing robotics to the forefront, promising to enhance efficiency, safety, and productivity on building sites.

While artistic interpretations of robots in architecture, like those seen at the Venice Architecture Biennale, spark the imagination, there is a sense of anticipation that the practical, real-world robotic systems now emerging could completely transform the construction sector.

These are not just concepts; they are functional machines and systems tackling tangible construction tasks, from laying bricks to installing elevators and even 3D printing entire structures.

Some might argue that construction robotics remains more a dream than a widespread reality. It’s true that the sector is still significantly less automated compared to others like manufacturing, which recognized the potential of robotics as early as the 1950s.

Even logistics, beyond advancements in vehicles, has only seen significant robotic integration in warehousing in more recent years. Other sectors, such as finance and computing, are inherently highly automated.

Construction, arguably one of the sectors most in need of robotics and automation, has been slower on the uptake.

This isn’t entirely surprising: until recently, few companies had developed robots robust or versatile enough to effectively replace or augment human tasks on a dynamic and often unpredictable construction site.

Now, however, the landscape is changing rapidly. An increasing number of companies are launching innovative robots designed to automate tedious, time-consuming, or dangerous tasks.

From precise floor marking to the automated assembly of entire homes, these machines are poised to reshape the industry.

Let’s delve into some of the most interesting and useful construction robotic systems being developed and evaluated in the industry now.

A glimpse into a more automated construction site

1. The Concert modular construction robot, developed by researchers, is a versatile system designed for on-site assembly tasks. It focuses on the precise placement and connection of modular building components, aiming to speed up the construction process for prefabricated structures and improve the quality of assembly through robotic accuracy. This system is envisioned to work alongside human crews, taking over repetitive and physically demanding aspects of modular construction.

2. Schindler’s Robotic Installation System for Elevators (R.I.S.E.) is an innovative solution designed to automate the installation of elevators in high-rise buildings. This robot can autonomously drill holes and set anchor bolts, tasks that are traditionally labor-intensive and carry safety risks for human workers. By improving precision and working around the clock, R.I.S.E. aims to significantly speed up elevator installation, a critical path item in building construction.

3. HP’s SitePrint is a robotic layout solution that autonomously prints complex construction site layouts directly onto floors with pinpoint accuracy. Instead of manual marking methods which can be time-consuming and prone to errors, SitePrint uses sophisticated navigation and printing technology to transfer digital plans to the physical site, improving efficiency and reducing mistakes in the crucial early stages of construction.

4. The Hadrian X, developed by Australian company FBR (Fastbrick Robotics), is an autonomous bricklaying robot designed to revolutionize wall construction. Mounted on a truck for mobility, it features a long telescopic boom and utilizes a 3D CAD model to precisely lay bricks or blocks much faster than traditional manual methods, potentially building the walls of a standard house in a significantly reduced timeframe.

5. An ABB robot was instrumental in the 3D printing of a local German Red Cross headquarters. This industrial robot arm, equipped with a special print head, precisely extruded concrete layer by layer to form the building’s walls. This project demonstrates the potential of robotic 3D printing to create complex architectural forms efficiently and with potentially reduced material waste.
