# Miniature Building Robots The Minibuilder Robots Can 3D-Print Large-Scale Structures By Rahul Kalvapalle | Published 2014-06-19 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/minibuilder References: [gizmag](http://www.gizmag.com/minibuilder-robots-3d-print-large-scale-structures/32573/) & [iaac.net](http://iaac.net/printingrobots/) A team of researchers at the [Institute for Advanced Architecture of Catalonia](https://www.trendhunter.com/trends/moca-home) in Barcelona, Spain are using [mobile 3D printers](https://www.trendhunter.com/trends/bodxl) -- dubbed 'Minibuilders' -- to print large-scale structures directly on site. The robots are called 'Minibuilders' because of their size, with the largest robot being only 42 centimeters wide. The robots work in teams of three, each of which carries out a unique function in the building process. The robots work on their own task but coordinate with each other throughout the process. Each Minibuilder follows instructions provided by a central computer fitted with sensors and positioning technology. Another robot provides the building material to eah Minibuilder as required. The Minibuilders have so far only created one demonstration piece that sits in the Design Museum of Barcelona. However, it is hoped that the robots will eventually be able to [work in swarms](https://www.trendhunter.com/trends/tiny-robot) to construct full-sized structures. ## Trend Insights (Trend Hunter) - Score: 3.3/10 - Popularity: 20% | Activity: 72% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [AI](https://www.trendhunter.com/ai) ## Key Themes ### Why This Trend Is Growing - **Mobile 3D Printing:** Developing smaller, mobile 3D printers that can construct large-scale structures on site is a new trend. - **Collaborative Robotics:** Robots working in teams and coordinating with each other during the building process is becoming a common trend. - **Construction Automation:** Using robotics to automate the construction process with high precision is emerging as a new trend in the industry. ### Industries Being Reshaped - **Construction:** The construction industry can benefit from using mobile 3D printers and collaborative robots to build structures on site more efficiently and accurately. - **Robotics:** Developing mobile, collaborative robots for construction applications presents an innovative opportunity for the robotics industry. - **Architecture:** The architecture industry can benefit from using robotics and 3D printing to create innovative and complex structures with greater precision and efficiency. ## Related on Trend Hunter - [3D-Printed Neighborhood Homes](https://www.trendhunter.com/trends/wolf-ranch.md) - [Record-Breaking 3D-Printed Neighborhoods](https://www.trendhunter.com/trends/icon-and-big.md) - [Compact 3d-Printed Housing](https://www.trendhunter.com/trends/tiny-house-lux.md) - [Multidirectional Miniature Robots](https://www.trendhunter.com/trends/multidirectional-miniature-robots.md) - [Large-Format 3D Printers](https://www.trendhunter.com/trends/bambu-lab-h2s.md) - [Qatar 3d-Printed Building Plans](https://www.trendhunter.com/trends/bodxl.md) - [Voice-Led Fabrication Robots](https://www.trendhunter.com/trends/speech-to-reality.md) - [Fully Recyclable 3D-Printed Homes](https://www.trendhunter.com/trends/biohome3d.md) - [3D-Printed Tall Concrete Towers](https://www.trendhunter.com/trends/the-tor-alva.md)
