I could have benefited from this in the construction of our house. Riddled with inaccuracies, the engineer signed off on the foundations, but we found out when the walls were up that the builders used the internal dimensions as exterior dimensions. So our house is smaller by ~250mm on each side.

We had to make so many compromises and wastages as a result. Bathrooms now smaller if we want to keep other rooms the same, bathtubs couldn't fit, aw man.

Then when the house went up to 2nd and 3rd levels, the staircase was narrow and wasn't connecting between the levels. That alone delayed us by 3 months as we had to get the architect to build a 3D model of the affected area so we could figure it out. We have to hoist furniture up through balconies as it can't fit through the stairs.

I think having some machinery that minimises human error would be very helpful.

Cool! From HP! The robot only costs $1,500 but a two pack of extra sharpies for it costs $48,000. Before you can use it, you must install 5 petabytes of HP drivers.

Weirdly it turns out to be cheaper/faster than paying a human being to do the same thing in use cases where you have large concrete slabs with complex walls/casework layout

I wonder how it avoids pipes stubbed up through the slab, or electrical EMT, etc. or how it avoids mistakes made during the rough-in. What if the plumber missed a drain or supply by an inch? Guessing the robot doesn't adjust its outline. I.e. if a sewer stub is wrong by a few inches, the wall needs to be moved to fit the toilet, or the slab needs to be busted up and the sewer line relocated. I suppose if it gets some…

You have adjusts due to its detectors and it has a prism on it and is being continuously tracked by a total station.

It can correct course due to deviations in floor surface or obstructions pretty well.

As a high-end residential GC, I'm very interested in this product. We have incorporated Leica Totalstation and BLK360 into our projects. It assists confirming layouts, as-built conditions, and communicating with design professionals working remotely.

We find it pencils out on jobs with large OH /pan deck slabs or SOGs over 12000SF

    ## How it works
    ### CAD preparation
    1. You need a 2D CAD file. If you have a 3D model, convert it into a 2D .dxf CAD file.
    2. Insert additional printing information and instructions and use the HP Plug-in to get a robot-ready file.
    3. Save the 2D .dxf CAD file into the cloud. Maintain version control and share revisions with field operators.
    ### Site Preparations
    1. Clear layout area as for manual layout. No need for a broom-swept floor.
    2. Make sure that control points used for Robotic Total Station setup are accurately marked. The layout is as accurate as the control points.
    ### Solution setup
    1. Set up the Robotic Total Station and shoot the control points. 
    2. Lock the Robotic Total Station to the robot tracking prism.
    3. Connect the Robotic Total Station wirelessly to HP SitePrint through the user interface (tablet, phone, laptop, etc.).
    ### Job execution
    1. Open the CAD file on the control panel, select the print area, and submit the job.
    2. Maintain a line of sight between the robot tracking prism and the Robotic Total Station. 
    3. Choose between different inks for different types of layouts.
    4. The robot avoids collisions with obstacles. 
    5. HP SitePrint is robust enough to work on rough and bumpy surfaces.
    ### End-to-End management
    1. HP SitePrint cloud allows sharing of the latest CAD files with all stakeholders, so you can monitor job progress from the office and manage accounting reports.

Anyone know what this thing does...?

It reads construction blueprints and prints the necessary lines on the floor. Workers use the lines to assist with building walls, drilling holes, all the stuff that would need careful measurement before executing.

I think the market is more towards industrial scale sites like data centers and Amazon warehouses and factories where equipment installation is happening right behind JIT layout.

Places where high precision matters and services aren’t connected to the endpoint at the slab. That’s not most construction because progressive refinement is how most things are built.
