A 3-D imaging robot could help construction workers make fewer mistakes

Using lidar and a healthy dose of AI, a new robot can check that building projects are going to plan. How it works: Once a construction site shuts down for the night, a small robot deployed by startup Doxel can get to work. Using lidar, it scans the site and uploads data to the cloud. There, deep-learning algorithms flag anything that deviates from building plans so that a manager can fix it the day after. Why it matters: If errors aren't noticed immediately on a work site, they can create compounding issues that take time and money to put right down the line.
