Approximately 20% of construction costs are wrapped up in fixing errors. Barcelona-based Scaled Robotics wants to minimize the rework by automating progress monitoring with autonomous mobile robots. 

Leveraging lidar and autonomous vehicle technology (similar to what’s used by Google cars to map the world), Scaled Robotics built a WALL-E doppelgänger to navigate and build maps of construction sites by fusing images, video and data captured by its robots.
