       | Disney's been doing awesome work with "Living Characters", like a
       | Mickey that moves his mouth or a BB-8 that can roll around. But
       | for various reasons, they never tend to make it into regular
       | usage.

       | If you have a few hours over Christmas break and want to watch a

       | you'll be delighted by it), I highly highly recommend this video:

           | 
           | Nothing about all that tech makes me think Olaf could

           | Disney does a ton of R&D that doesn't directly make it into

           | know the practicality at the start, like any good R&D.

             | In the video, one of the presenters removes and reattaches
             | Olaf's nose. The robot laughs and loves it. I thought to
             | myself, how many kids tearing at that wear item will this

           | Much like Olaf (and many before him... dinosaurs, WALL-E,
           | talking characters, etc), it was implied he'd wander around
           | the parks. But it tends to happen for a short amount of time,

           | says that: Olaf will be part of a 15 minute temporary show,

           | 
           | Maybe I'm wrong, but I've seen this exact thing happen a

             | I expect you're correct. While it's fantastic tech, it's
             | also very expensive to keep highly-precise, carefully
             | calibrated micro-machinery like this aligned and operating
             | 12+ hours a day outdoors where temps vary from 50-110
             | degrees. Disney thinks in total cost of operation per hour
             | and per customer-served.
             | 
             | While there's probably little that's more magical for a kid
             | than coming across an expressively alive-seeming automaton
             | operating in a free-form, uncontrolled environment, the
             | cost is _really_ high per audience member. Once there are
             | 25 people crowded around, no new kid can see what all the
             | commotion is about. That 's why these kind of high-
             | operating cost things tend to be found in stage and ride
             | contexts, where the audience-served per peak hour can be in
             | the hundreds or thousands. For outdoor free-form
             | environments, the reality is it's still more economically
             | viable to put humans in costumes. Especially when every
             | high-end animatronic needs to always be accompanied by
             | several human minders anyway.

               | Disney has problems with that. Their Galactic Starcruiser
               | themed hotel experience cost more to the customer than a
               | cruise on a real cruise ship, and Disney was still losing
               | money on it. The cost merely to visit their parks is now
               | too high for most Americans.
               | 
               | It's really hard to make money in mass market location-
               | based entertainment. There have been many attempts, from
               | flight simulators to escape rooms. Throughput is just too
               | low, so cost per customer is too high.

               | A little mobile robot connected to an LLM chatbot, though
               | - that's not too hard today. Probably coming to a mall
