Foster + Partners have teamed up with Boston Dynamics as part of their early adopters’ programme for Spot, the semi-autonomous robot, to investigate how cutting-edge technologies can push the boundaries of both design and construction. Using 3D laser scanners mounted on Spot we are capturing and monitoring construction progress on building sites, as well as changes to furniture layouts in completed buildings. These repeated laser scans allow us to compare our digital design models to the reality as-built, and to build 4-dimensional models of space, to understand detailed changes over time.
