On Site Robotics is a collaborative project of IAAC and TECNALIA, which demonstrates the potentials of additive manufacturing technology and robotics in the production of sustainable low-cost buildings that can be built on site with natural materials.
Combining technological advances in robotics (cable robot and drones), natural materials and CAD/CAM software, the aim of the project, which will be presented at Construmat 2017, is to bring automation to the construction site, as well as allowing the production of high-performance buildings and their monitoring in real-time during the construction.
The 3D Printing System presented in On Site Robotics is introduced to 3D print large-scale construction parts, and even small-scale buildings, made from natural materials. This system includes the cable robot Cogiro with an integrated CNC control, which is able to automate the movement of the 3D extruder with precision.
Thanks to the use of cables operated by servo-controlled winches with easy assembly, maintenance and reconfiguration, the printing can happen in a very wide range of workspaces, and even directly on the construction site.
The system also integrates an extruder and a natural, biodegradable, recyclable and local clay-based extrusion material, based on the Pylos project. In addition, a custom script integrated in the CAD software allows to easily translate the complex forms of 3D design in the robotic trajectories.
