Hannover Messe 2025: Mind The Reality Gap
Last week, I joined 127,000 of our closest friends in Germany for the Hannover Messe trade fair, which once again showcased all that’s new and interesting in the smart manufacturing world. Events like this always exist in a bit of a bubble, but the reality gap between lovely spring sunshine, beautiful cherry blossoms, and breathless AI boosterism inside the showground and tariffs, uncertainty, and lengthening sales cycles outside felt particularly wide this year. So What Did We See? Robots everywhere. Big and small, fixed and mobile, wheeled and legged: In some halls, utilitarian autonomous mobile robots were the point, and prospective buyers dug deeply into questions of carrying capacity, connectivity, range, and fleet management. Elsewhere, the flash of a robot leg (or four) drew crowds to the booths of the Bundeswehr (Germany’s army), Siemens, and other giants of the industrial world. In line with Forrester’s prediction, humanoid robots were a rarer beast. In a week of searching, I saw two (from Unitree and Sanctuary AI), and only one (Unitree’s G1) had legs. Forrester’s advice, to focus on the use case rather than the form factor, remains as relevant as ever. AI everywhere, too. Last year, I commented that “everyone had an AI story, even if few made much sense.” There was still plenty of that in 2025, but I also saw some evidence that AI was being put to practical use. Almost everyone had a chatbot to show, and some of them were quite clever. PTC showed a nice enrichment of the CodeBeamer asset lifecycle management application, using Microsoft’s AI tools to reduce ambiguity and contradiction in formal statements of requirements during product design and manufacture. Siemens enriched its existing AI offerings with a new industrial foundation model, trained on domain-specific concepts and able to process engineering diagrams as well as the text and images that more general-purpose tools manipulate. Embodied or physical AI. Interesting things happen when robots and AI get together, and some early indications of that were also on show. Sanctuary AI’s humanoid robot on the Microsoft booth might have been legless, but it had very clever hands and an impressive ability to respond to its environment. A small robotic arm on the TCS booth looked much like all the other robotic arms at the show, except for the scrawled signature of NVIDIA CEO Jensen Huang. Behind the scenes, his company’s Cosmos model helped the TCS team train the arm to cope with a wide set of situations. I’ll be diving more deeply into both in some embodied or physical AI research this year. Virtual PLCs. Audi, Intel, and Siemens have all been talking about different aspects of a project to virtualize line-side programmable logic controllers (PLCs) for several years, but industry conservatism, network latency, the control loop, and an engineer’s understandable desire to see — and touch — the little box of tricks responsible for keeping their multimillion-Euro industrial process moving smoothly conspire to slow the virtualization of operational technology workflows. Audi and Siemens have taken the solution into production, with Audi’s car body assembly line in Neckarsulm now controlled by virtual PLCs (TÜV-certified as fail-safe) installed on standard IT infrastructure in a data center 10 kilometers from the plant. According to Siemens, a further 40 customers are evaluating the solution. Unified namespace. The unified namespace (or UNS) was mentioned at a lot of booths this year, but it’s a term that risks becoming too diluted to be useful. Some (like Automation, HiveMQ, Litmus, and Sight Machine) mostly used the term in the pure sense originally intended by Walker Reynolds. Others were less precise and really just talked about pouring data from different systems into a single data lake: There’s not much unification happening there! Both can be useful, but the extra work to add context, semantics, and structure provides the real differentiation that makes a true UNS special. More data hubs and fabrics. We talk about the digital industrial platform at Forrester (new report on the topic coming very soon), and one important aspect of this is providing a way to more easily share data across application, organization, or workflow silos. There’s some overlap with the UNS, but we also see vendors offering their own software solutions. Autodesk Forge, AVEVA Connect, Hexagon Nexus, and others are addressing this challenge, and new options like GE Vernova’s Proficy Data Hub and HiveMQ’s Pulse were being promoted at the show and should be generally available later this year. Merck combines physical and digital to improve quality and traceability. It’s a pretty specific use case, but it popped up on at least two stands. Merck launched the M-Trust “cyber-physical trust platform” at CES in January, which ties digital product information to specific attributes of a unique physical product such as specific pigments embedded in the ink used to print its label. There’s a lot to explore here in terms of ensuring trust and authenticity up and down the supply chain and making the solution cost-effective for cheaper products. But integrations like those on show in Hannover help: On the Zebra stand, the special reader required to spot inclusions in ink and paint was embedded into a regular Zebra handheld scanner, and Siemens Merck showcased the SmartFacturing Studio that supports modular production of pharmaceuticals with a lot of help from Siemens hardware, software, and the Xcelerator platform. This touches on some similar ideas to the digital product passport, which I also saw good examples of and will be exploring in more depth in a report later this year. Oh, Canada! There’s usually a partner country at Hannover Messe. They’re selected months ahead of the show and normally don’t make that much of an impression after some of their senior politicians, diplomats, or executives say worthy things at the launch press conference. This year’s choice, Canada, was fortuitous and well placed to connect with broader concerns around tariffs and geopolitics. Canadian startups, companies, and high school robotics teams made the most of the opportunity to show their capabilities and
