There's a video of the robotic building woodworking system for building components.[1] (This article is from their VC firm.) The video is so bad that, if weren't from ABB, a legit robotics company, it would clearly be a scam. They never show the robot at work for more than 1-2 seconds at a time. It's not clear how much of the job it does. The video is about 90% filler - quick cuts, talking heads, scenery. It's not even clear what they're making. All they show is a robot moving some wood around.

Assembling building panels with robots in factories with has been done, but it takes a bigger factory, because what's being made is large.[2] That's a legit video showing the whole process of making housing panels.

I visited Re:frame Systems[1] in Boston last month and it was pretty cool to see their system which was apparently primarily comprised of a series of magnetic stops on an angled work-surface tended by a giant robotic arm. Cut to length lumber would be fed in on batched trolleys and the arm would compensate for non-square lumber while pinning individual pieces in place then finally nailgun them together in to a completed structural frame. These frames then moved flatpack-style to a second site in the factory for assembly then manual fit-out. I was quite surprised at how slow the arm was, but it didn't really matter because a human would likely take longer by the time they went up a ladder a few times, had a break, and took time off for weather interruptions. They had a pretty impressive team drawing experience from most of the larger US robotics applications and were moving from single level to double level housing, with more elaborate structures planned in future.

Another of the companies mentioned, Facit, has a lot more videos and information about their build process:
