Equipped with a precision-motion robotic arm and powered by solar panels, the machine sprays an insulation foam mold on the ground and then fills it with concrete – it completed the walls of a 50-foot-diameter, 12-foot-high dome in 14 hours.
MIT's system is a massive robotic arm attached to a track vehicle.
And human workers can attach any 'conventional (or unconventional) construction nozzle' that is needed for a certain task, such as pouring concrete or spraying insulation material.
To demonstrate the technology, the team constructed the walls of a 50-foot-diameter, 12-foot-high dome in 14 hours of 'printing' time.'To me it's not merely a printer,' said Neri Oxman, group director and associate professor of media arts and sciences who also worked on the project, 'but an entirely new way of thinking about making, that facilitates a paradigm shift in the area of digital fabrication, but also for architectural design.''Our system points to a future vision of digital construction that enables new possibilities on our planet and beyond.'During the proof-of-concept, researcher were able to show that it can easily work alongside with other construction equipment and 'will fit existing building codes without requiring whole new evaluations', said Steven Keating Ph D, a mechanical engineering graduate and former research affiliate in the Mediated Matter group at the MIT Media Lab.
Bricks are fed onto a conveyor belt that travels along a long robotic arm, or telescopic boom.
Je kunt de grassprietjes tijdens een voetbalwedstrijd bijna tellen.
Overigens hangt daar wel een flink prijskaartje aan.
The robot has a boom 92ft (28 meters) long that is connected to its main body.
At the end is a robotic 'hand' that can grab bricks, pick them up, and place them down in sequence.
