Barriers to Robots in Construction
Barriers to Robots in Construction:
Almost unique context on each project and site.
Unstructured, dynamic nature of the construction site, the hazards and difficulties presented by temporary works, weather and, sometimes, the shear scale of activity mitigate against greater automation.
Initial investment.
