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.

Ok and I thought having our inground pool installed crooked was bad. Where you able to get any legal/financial clawbacks because of all the hassle?

pavel_lishin

Translating for folks not natively familiar with millimeters - this is 25cm, or about ~10 inches.

Doesn't sound like a lot, but you're losing a foot and a half across a dimension of a house. That's very easily into the "Bathtub doesn't fit" territory.

TheSoftwareGuy

That's awful. I hope you were able to recover damages from the builders

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.

tacticalturtle

Most of the 5 petabytes is a model used to determine if your sharpies are counterfeit.

They remotely brick your Sharpies even if they are original because of a bug in the software

realitysballs

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

profsummergig

Don't give them ideas.

lloydjones

You beat me to it!

tguvot

do you have sharpie that won't grind down to zero on concrete after 3ft ?

tomovo

Not on genuine HP concrete.

tguvot

Hp concrete actually exists

I remembered hearing a podcast about a startup robotics company doing the same thing; a little search and they actually have a comparison page between their product and HP's:

Thank you. I wondered immediately on seeing this if HP had just acquired those guys.

So Dusty is for SMBs and SitePrint is for clueless Corporations, like Oracle.

Take your pick:

If you give it a big job, it freezes halfway and just spins its wheels as fast as it can until you unplug it.

It refuses to paint yellow lines when it's out of blue paint.

It asks you for feedback after doing any and every job.

It doesn't have good Linux support.

It has no off button. The only modes are printing, standby at half power, or unplugged.

When you want to just print a small blue square on the floor, it makes xxxjuukkktsssssruuuuukkkttt sounds for 5 minutes, pauses for another 2, zooms at max speed to the location on the floor, pauses for 10 seconds, and begins doing the actual job it was designed to do, but does it in a shade of blueish brown.

epic slashdot post fellow redditor. here, have this thinkgeek tshirt that says "no i will not fix your printer". le epic

+ If your subscription expires while it's printing, it freezes and you have to carry it back home.

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 of this wrong, it'll be obvious, and a human can correct it.

brudgers

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.

realitysballs

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.

brudgers

The concern is not the course, but the ability to adjust a layout due to deviations from the plan due to normal construction errors.

For example a pipe might not be in the location shown on plan for many reasons ranging from simple human error to a delta between the plan location when the pipe was layed and the time the robot got its data…keep in mind that when the pipe went in there was only dirt, not anything to accept ink.

In the 1980s there were “turtle graphics” robots if LOGO wasn’t real enough for you,

bitwize

The Logo Turtle was originally a robot. The on-screen turtle was added later to make Logo and its pedagogy economical for the computers schools were likely to have (a single Apple II per classroom, if that).

I can only see this getting used by very large scale contractors. Framers for your standard house are probably just going to keep using chalk lines (maybe a laser line too these days). "Precision up to +/- 1/32 inch" really isn't necessary in framing.

Groxx

agreed, though I can see it making some sense in those specific situations, e.g.:

>PCL reduces cost by 86% on interior curved lines layout at Vancouver airport

for random bits of complicated-shape fashion in a giant flat open area, I can see how it could almost immediately pay for itself.

that said... at that point it's probably competing with "we put a projector on the ceiling for a day, and went over the lines with chalk". which is quite cheap.

brudgers

Some small builders probably will because it will make business sense for their specific business.

And others will because some builders are as attracted to gee-whiz its new and shiny as in any other business.

I wonder if this is in collaboration with this group

This one called Dusty

Oh nice someone else mentioned it

As a specialized commercial contractor and former large format printer, I won't touch HP equipment with 10 ft. pole saw..

rkagerer

I saw the title and hoped someone had finally built a tool that can correctly print websites with fidelity.

HP gets a lot of crap for home printer quality and ink DRM, but does still have some neat products like this.

The industrial printers for example, especially the PageWide Web Press line are impressive. The T1100 is a huge beast.

Then there are the life science products that can do precision dispensing of fluids for life sciences and drug discovery. Some of them also do individual single live cell dispensing.

PaulHoule

(1) As much as people complain, home inkjet printers do a remarkable job of printing high quality art reproductions and photos at low cost relative to alternatives, (Sure offset litho is cheaper… if you are running 10,000 prints)

(2) The key to this using quality materials. You’ve got to use good coated paper (which is relatively expensive.). You can mostly trust OEM ink although I found low-end EcoTank printers use ink that fades in six months although the higher end models like the ET-8550 are better. Look at forums and you will find many versions of “I was trying to print borderless and all I got was this inksplosion” and the common denominator is third party inks. There could be testing of third party inks that proves they are comparable to or even superior too the OEM links but as it is there is no testing because… they target a consumer who doesn’t care.

curiousgal

It's not about the technology itself, it's about everything that surrounds it, the software, the commercial side. I will go out of my way to avoid HP.

TBH my LaserJet 451dn died recently and I bought brother colour 3270cdw. The quality of colours is awful, almost unbearable. I remember I could print a photo with HP but the Brother fails that task spectacularly for some reason - quickly colours go to overdrive and bleed

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.

realitysballs

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