HP's construction robot puts blueprints on site floors

Construction workers might soon spend more time building and less time preparing. HP has unveiled a SitePrint robot that autonomously prints layouts on construction site floors. With the help of a remote control tablet and cloud tools, the machine can outline walls, doors and other elements with little intervention — it can avoid unexpected obstacles, including steep drops. The company claims the bot can finish a layout in a "fraction" of the time humans require, although this will vary by the complexity of the project.
