Psst… We received a tip…

Olaf was supposed to charm the crowd, but during a performance at Disneyland Paris last week, the free-roaming Olaf froze, fell backward, and lost his carrot nose in front of guests!

It is easy to build a demo that looks magical under controlled conditions. It is much harder to build a character that can do that in public, on cue, again and again, without face-planting in front of a crowd.

While Disney has been showing off a self-walking Olaf, Universal just published a patent. It isn’t a truly free-roaming robot like the Olaf that spectacularly fell over, but it is a system that can make a figure look like it is walking through carefully coordinated support, motion, and timing.

This week’s patent is Universal’s Animated Figure Walking Mechanism. How do you make a character feel alive without asking a machine to do more than the real world will let it handle?

Universal patented a system for making a figure look like it is walking, while the machine underneath does a lot of the hard work. In theme parks, the wow moment is only half the job. The other half is doing it repeatedly, in front of thousands of people, without the thing eating concrete. The application was filed by Universal City Studios LLC, the same company behind Universal’s parks and attraction tech work.

This patent explains an illusory effect that tricks the viewer into thinking the animatronic is walking.

At the center of the system is a hidden cart. It runs along a concealed track and carries the entire figure forward. That's what actually moves the character. The legs never push off anything or bear the weight of a real stride.

But Universal added a layer of choreography on top. As the cart moves forward, the legs swing, plant, and lift in a timed sequence. A controller coordinates the limb movement with the cart movement so the two read, to an audience, as a single coherent action. Step, plant, push, lift.

Theme parks have had moving limbs for decades. The novelty is the coordination. The knee bends. The foot appears to stay planted while the body moves over it. None of that is the figure actually walking. The result is an ambulatory effect, aka a convincing walking illusion, that doesn't require the figure to balance, recover, or catch itself. The hard problem of walking gets handed off to the cart. The figure just has to look the part.

WHICH CHARACTERS COULD UNIVERSAL APPLY THIS TO BEST?

This makes the system a strong fit for characters that feature heavy, eerie, theatrical bodies. Think someone advancing slowly through smoke, or turning spookily. Frankenstein’s Monster feels a promising example. Universal’s Dark Universe land is already built around Dr. Victoria Frankenstein, monsters, and Gothic spectacle, and Monsters Unchained: The Frankenstein Experiment is exactly the kind of setting where a big, weighty, half-human figure taking a few convincing steps.

Frankenstein also makes sense for a more practical reason, that he does not need perfect human motion. In fact, perfect might hurt the effect. A slight heaviness, a deliberate pace, even a touch of unnatural stiffness could make the figure feel more threatening.

You could imagine in-film use too. A horror movie could use a system like this for a close shot where a creature lurches toward camera, or a lab-built monster crosses a hallway with real weight and real shadows. Then visual effects could clean up whatever support is visible. That would be useful. But film only needs the shot to work a few times from the right angle. Theme parks need the effect to survive daily operation, safety checks, maintenance cycles, and crowds. That is why the better commercial bet is still attractions, not movie sets.

Disney said their Olaf animatronic had to learn to balance on “an unstable surface” for his boat show at Disneyland Paris, and days later a guest-facing Olaf froze, fell backward, and lost his nose in a viral clip. (Disney Experiences)

Universal’s Epic Universe has more than 50 experiences across five worlds, including Dark Universe. When you are building at that scale, character tech has to be repeatable, durable, and safe enough to run in front of guests every day. There is real value in a lifelike character that can reliably hit its mark. (Comcast Corporation)

Disney is the clearest comparator because it is already spending real money on this exact magic trick. Its BDX droids are described by Disney as “the first of a new generation of expressive, free-roaming robots,” and Disney’s Olaf was trained in simulation to stand and walk on tough surfaces, including a boat.

Universal is solving the same guest problem with a different bet. Universal invested more than $10 billion in new and existing Universal destinations across the U.S. from 2018 through 2024, and Epic Universe alone opened with five worlds and more than 50 experiences. (Comcast Corporation)

In-film use solves it a little differently. Shops like Wētā Workshop build custom robots, props, puppets, and partial animatronics for the shot that matters, then let editing and VFX do the cleanup. (Wētā Workshop)

The top 25 theme parks in the world pulled in almost 246 million visits in 2024. Disney alone drew about 145 million visitors across its parks in 2024, while Universal drew nearly 59 million. (Tea Connect)

Disney’s Experiences segment generated $36.2 billion in revenue and $10.0 billion in operating income in fiscal 2025, while Comcast’s/Universal’s theme parks segment generated $9.8 billion in revenue. Disney has also said it plans to invest roughly $60 billion in parks and experiences over about ten years. Comcast says it invested more than $10 billion in new and existing Universal destinations across the U.S. from 2018 through 2024. 

Olaf is a good reminder of why that matters. Disneyland Paris drew 15.8 million visitors across its two parks in 2024, and when Disney’s new free-roaming Olaf face-planted last week, the clip ripped across the internet. One version of the TikTok passed 4.5 million views, and the jokes on X pushed the moment past 10 million views there too. That is the market in one cute little wandering snowman. (PixieDust.be)

If you are looking for a clean animatronics gold rush, it is not really there. The money is pouring into the bigger bucket next door of humanoid and embodied-AI robotics. Robotics startups pulled in just over $6 billion in 2025, and humanoid robot startups alone raised more than $2.65 billion in 2025, up 152% from the year before. Goldman Sachs thinks the humanoid robot market could hit $38 billion by 2035. (Crunchbase News)

The biggest checks are going to real-world machines that can move, recover, and work around people. Figure (general-purpose humanoid robots, specialising in household work) raised $675 million in 2024 at a $2.6 billion valuation. Apptronik (building AI-powered humanoid robots for manufacturing, logistics, and retail) closed a $403 million Series A in 2025, then added another $520 million in 2026 as investors piled in behind its humanoid robot push.

Closer to Universal’s lane, Engineered Arts, which builds social humanoid robots for places like theme parks, science centers, and conventions, raised $10 million in late 2024 and said that brought total funding to $16.2 million. (Business Wire)

Disney is partnering with Nvidia and Google DeepMind to push its robotic character platform forward, while Universal is filing its own IP around a safer, more controlled walking effect. Venture money is chasing broad humanoid platforms, while the parks are still chasing narrower, more dependable show tech.

While Disney chases free-roaming robot magic, Universal looks like it is protecting characters that feel alive, hit their mark, and stay upright in front of millions of guests. In a parks business measured in tens of millions of visitors and billions in revenue, that kind of reliability is valuable. 

The smartest animatronics may be the ones that cheat just enough to sell the illusion without turning into a viral maintenance problem. After Olaf’s fall, that might become an appetising strategy.
