INSIGHTS FROM
INDUSTRIAL AUTOMATION

Newsletters, opinion pieces, and insights about realvirtual.io, Virtual Commissioning, and Industry 4.0.

Lock-In Has No Future. AI lets competitors build faster and big organizations are too slow, so closed-source moats erode. Open plus AI over an MCP server is the durable bet.

I don't believe in the future of lock-in business models.

Siemens just showed the playbook at VivaTech, with Roland Busch on stage: heavily discounted engineering software for startups, an Industrial Copilot that writes and validates code, all under the Industrial AI revolution banner. But a discount that steep is less strategy than signal. When a startup can prompt a working tool in an afternoon, the old enterprise license is hard to justify.

The whole bet rests on the lock-in holding later, and that is getting thin from two sides. AI lets a competitor build in weeks what took years, and the incumbents are too slow to react, not because the people are weak but because big orgs decide at big-org speed. By the time the discount becomes lock-in, smaller teams have shipped around it.

There is a catch the closed vendors miss too. An AI agent is only as good as the code it can read. On open source it understands and extends the system. Behind a closed binary it is guessing. The better agents get, the more source access decides what they can do, which is exactly what a locked platform withholds.

So we bet the other way. Open instead of closed, AI on the digital twin over an open MCP server, not inside one vendor's garden. When everyone can build faster, open is the durable choice. Whoever is fast and open does not need lock-in.

Build your first digital twin in Unity: take a conveyor FBX from CAD, add materials, a Transport Surface, a Drive and a Source, and watch it move parts with the free realvirtual.io Starter

Build Your First Digital Twin in Unity: From a CAD Model to a Moving Conveyor

A digital twin starts as plain geometry. Here is how you take a conveyor the way it arrives from CAD and turn it into a machine that actually moves parts in Unity, with the free realvirtual.io Starter and no code.

You can lay out a whole production line without opening a single engineering tool.

No CAD seat. No app. No cloud. No subscription. Just a browser tab.

Drag your components onto the grid, arrange the line, done. The parts you plan with are plain GLB files, the same open 3D format the rest of realvirtual Web runs on. Nothing else to maintain.

Which means the library is yours. Every line builder and machine builder already has their components. Label a GLB once, drop it in, and it's a planner block your whole team reuses. Keep them built in, in a local folder, behind a URL, in a GitHub repo, or pull them from the Asset Store.

Here's the part I like. The labeled component you drag into the layout is the same one that later becomes the 3D HMI. You plan the line with it, the machine ships, and that exact part is now clickable in the browser, carrying its documentation and its live signal. One labeled GLB at the front of the lifecycle and at the end of it.

This is the PLAN side of realvirtual Web. Before commissioning, before the machine ships, a planner or sales engineer roughs out the layout the customer is actually buying. Same platform that later delivers and monitors it.

Online now. Free to use. Try the live demo.

Want a component to behave differently? Script it in TypeScript or JavaScript, let the AI write the code, and off you go.

Most robot paths still get taught at the pendant. You stand there and jog the robot point by point.

6.3.4 lets you do it on the twin instead. Teach the path in Unity, export it as controller code. ABB RAPID, KUKA KRL, Fanuc TP, SEW and Wandelbots. Live preview, then copy it or save the file.

Cobots work now too, and the export does blending, so the robot doesn't dead-stop at every point.

The clip is the Unity simulation, the cobot running a path I built from a handful of points in the twin. No real robot, no pendant.

Still beta. Treat the output as a starting point and check it before it goes on a real controller. If you run one of these brands, throw a path you know at it and tell me how it did.

Your machine docs belong to you. Static files you host anywhere, no cloud, online for 10 years.

Your machine's documentation belongs to you. Not to a cloud you're renting.

Two things never leave your side. Your CAD is never uploaded to process it. And the delivered docs aren't a hosted service either.

What you hand over is a stack of static files. The viewer plus your 3D files, that's it. No backend. No database. No login server. No subscription.

So you can put it wherever you want:

  • your own web server
  • an S3 bucket or any static host
  • the customer's intranet
  • or a USB stick that ships with the machine

And it runs. Still runs in ten years, because a static web server is about the most stable thing on the web.

That's exactly what the EU Machinery Regulation asks for from 2027: keep the documentation online for ten years, without being chained to a cloud vendor that might go under or kill the service first.

Your delivery shouldn't depend on us still being around. So we made sure it doesn't. Hand over the files, host them anywhere, and they keep working even if realvirtual is gone.

What is a digital twin in Unity? 3D geometry plus behavior: drives, behavior models, and PLC signals in realvirtual.io

What Is a Digital Twin in Unity?

People use the term digital twin for almost anything that looks like a 3D model. In realvirtual.io it means something specific: 3D geometry plus behavior. Here is what that actually consists of, explained on the Getting Started demo.

Since 2027 a machine manual can be a digital, interactive 3D machine instead of a PDF. EU Machinery Regulation 2023/1230

Since 2027 your machine's manual can live inside the software. Not a PDF attached to it. The 3D machine itself.

Almost nobody is doing this yet. That's the opportunity.

The EU Machinery Regulation 2023/1230 made it legal. Article 10(7) lets you hand over the instructions digitally instead of on paper. Paper is still fine, nobody forces you. You just have the option now.

The customer opens the machine in a browser, clicks the broken part, and the documentation is right there on it. No 200-page PDF. No part-number hunt.

And right now it sets you apart. Your competitor still ships a binder and a USB stick. You ship a machine people can actually use. That wins you the room in the sales meeting, not just goodwill after delivery.

One catch. Go digital and it has to stay online and downloadable for ten years. Most software won't be alive in ten years. So you can't tie your delivery to a vendor that might disappear. Us included.

That's why we made the realvirtual Web viewer open source. You self-host it, you own it, it keeps working even if we're gone. We make our money on the authoring side. The delivery stays yours.

We're writing it all up in a short Machine Information System ebook, out soon. In the meantime, try the live demo: web.realvirtual.io/demo

UnoPro Industrial Excellence — new sales and integration partner in Türkiye

We are happy to welcome UnoPro Industrial Excellence as our new sales and integration partner in Türkiye.

UnoPro Industrial Excellence is a Türkiye-based operational and organizational excellence company focused on Digital Lean Transformation, Industry 4.0/5.0, MES-IoT integration, Learning Factories, VR/AR-based training systems, and Digital Twin solutions.

UnoPro combines industrial hands-on experience, academic expertise, and implementation capability to support companies in building sustainable, human-centric, and data-driven transformation systems.

The company has actively designed and established multiple Learning Factory and Digital Transformation Center environments in Türkiye and is currently expanding its capabilities towards AI-supported Digital Twin and virtual commissioning solutions.

Welcome on board, UnoPro.

Just came back from Hannover Messe. As expected: "Physical AI" everywhere. Cloud-rendered digital twins. GPU clusters. Six-figure platform subscriptions. Complex systems built by specialists for specialists.

This is a dead end. At least for 95% of manufacturing companies.

The digital twin — as it's currently sold — is too complex, too expensive, and too locked-in to ever reach the people who actually need it: the operator on the shopfloor, the maintenance technician with a tablet, the service engineer at the customer site.

We built realvirtual WEB to change that. Because in 95% of use cases, a modern browser is all you need. Open source. One link. Any device. No cloud required. No specialists needed.

Click on a component in 3D — see documentation, spare parts, live sensor data. That's it. That's the digital twin that creates value.

And we're just getting started. Coming soon:
→ Layout planning directly in the browser
→ Discrete event simulation
→ Interfaces to external data sources like Unity Asset Manager

Keep it simple. Bringing 3D to everybody.

Physical AI. World Models. Cloud-rendered digital twins. Cool demos. Zero value for the guy fixing the machine at 2am.

Your maintenance technician still looks up spare parts in a PDF catalog. Your machine documentation lives on a file server nobody can find. And your "digital twin strategy" is a slide deck your management presented at a conference.

Here's a radical idea: what if a digital twin was just... a link?

See how Mauser Packaging Solutions is transforming the way machine documentation is delivered — interactive 3D, accessible to everyone on the shopfloor. No GPU farm. No hosting. No Lock-In. No AI buzzwords. Just real value for real people. Thanks to Nils Maier for supporting what began as a vision and is now reality.

Come see the Mauser demo live at Hannover Messe — Hall 17, Booth G44.

One link. Any device. Open source.

Closed Source Is Dead — AI killed it

Closed Source Is Dead. AI Killed It.

Investing in closed source software might be the worst long-term investment a company can make today. Not because closed source is bad software — but because AI coding agents work dramatically better when they can see the full source code.

Your HMI is Still 2D? Here's What You're Missing

Last week, I watched an experienced operator spend 15 minutes clicking through seven HMI screens to locate a sensor fault. The sensor was 2 meters from where he stood. The problem wasn't the operator — it was the interface.

Accelerating AI Training with Digital Twin Technology

How realvirtual.io AI Builder is changing the game — train AI vision systems within a digital twin environment, dramatically reducing development time and improving performance.

Let's Stop Buzzwording — A Call for Real Conversations

As I walked around Hannover Messe, one thing stood out: everywhere I turned, the same buzzwords — Metaverse, Industry 4.0, Digital Twin, AI. But are these words driving innovation, or have they become catch-all phrases that obscure the real work?

The Shifting Landscape of Industrial Simulation
