The objective of this paper is to present how robotics permits improvement of construction and building. The comparison will be made with the manufacturing industry for which the robots have operated for many years. To illustrate a robotic system developed to apply a new advanced Additive Manufacturing (AM) process will be presented: Batiprint3dTM. The proposed advanced technology consists of creating a complex wall of 3D-printed materials using a mobile and polyarticulated robot: two polymer-foam printed walls are used to encase a subsequent third wall made of concrete. By using 3D printing for the foam and extrusion of the concrete with the same robotic system, the technique creates jointly both the structure and thermal elements of the building. In the first part of this paper the composite foam/concrete 3D printing method are presented and the idea of a robotics system adapted for building on-site will be developped. In the second part, an experiment in full scale using this new walls 3D printing method will be presented, it is the construction of Yhnova, a real 95m² social housing. In the third part, other robotics solutions dedicated to construction will be presented. This technology Batiprint3d have been used to build a certified, validated and inhabited house; it is possible now to propose a synthesis of the impacts of this new advanced technology for construction.
