1. The article states "he’s soon making his debut at Disney parks," which is misleading to a casual reader who may not realize that Olaf will only appear on the day of his debut.
There definitely are some marketing mistakes that have led to that, and certainly a lot of these projects seem to be in the direction of "one day, maybe, these will be crowd pleasers", but it still seems to me a bit funny how often casual intepretation seem to be "I can't wait to touch and play with the new Lincoln animatronic at the Hall of Presidents". It's not an R&D failure for Imagineering to keep building cooler animatronics even if most guests will only ever see them behind glass or rope or in other areas just out of touch. That's always been Disney's way of using robots for magic. The dream of "one day I can touch them and play with them" certainly lives on, of course, and these projects seem walking a few steps at a time towards that dream, but it seems weird to dismiss them as failures when they turn out to be just "normal" Disney tools for magic that try to create an illusion of being right next to you but don't allow for touching.
I can see why you're confused. Either of those possibilities would be acceptable and exciting, neither are going to happen.
Olaf (like the walking droids, flying x-wings, etc. before it) has so far made one single appearance in the parks on an off day, which was treated like a photoshoot. The photos from that shoot will be used in park promotional materials for years, incorrectly giving casual observers the impression that this is something that happens regularly.
If Walt Disney had advertised the Lincoln animatronic as being a part of the 1964 worlds fair, but only exhibited it for a few hours one time, he would have been ridiculed too.
The character shape lends itself to a low center of gravity but the fluidity of the motion implies light weight or strong motors.
An angsty kid giving Olaf a good shove or kick could be expensive and fast moving robotics are either dangerous or brittle
In addition to the points you've highlighted, the examples in the video and the images of the character strongly suggest it'll be a soft outer shell. I'd be more worried about a kid shoving it finding themselves caught by an internal pinch-point than damage to the robot.
> things that can withstand the wear-and-tear of millions of guests.
Idk about that. It is just a plastic part with magnets in it. Sounds like it would be easy to replace on a regular basis.
I would be a lot more concerned about kids tripping the robot over if they are allowed to interact with the robot that closely.
Nothing about all that tech makes me think Olaf could withstand a hug from an excited kid.
Disney does a ton of R&D that doesn't directly make it into the parks, such as smokeless fireworks (they donated the patent for this) and their holotile floor (basically an endless VR room you can walk around). I imagine they don't know the practicality at the start, like any good R&D.
