Worked in food service for 16 years, started my own restaurant. So not a layman... (yes I know this is a logical fallacy; appeal to authority. So what)
But to answer your question, no. I don't think they've addressed these obvious issues.
Why the hell wouldn’t they have addressed those issues? It’s so fundamental that they’d be stupid to not have thought of what you’ve described. These people probably know a thing or two about what they are doing — this isn’t some kid’s science project. Other people have worked in restaurants too — I am pretty sure your concerns aren’t novel.
I knew a lot of people whose parents worked in the industry. Their kids would "help" out a bit (the parents hoped to pass on the restaurant) by working the front of the house, or doing some bookkeeping etc. This gave them a sense of the business without learning the hard side of it. The really long hours, the fear of going broke, the hassles of employing people. The endless cleaning, stocking, menu planning, working with vendors. The million details that all have to be done for the business to run smoothly.
Then the parents decide to step away from the business. Their children take over the business, and want to put their stamp on it. Modernize it. They update the menu; redo the decor. Aim for a better clientele. Try to remove the difficult parts of the business with technology. And the business fails. Because they didn't understand the myriad small decisions that lead to its initial success.
Restaurants are incredibly hard to start and run successfully. That's why franchises are so popular, they take some of the guesswork out, at the expense of giving up control and individuality.
At the end of the day, people want tasty food, at a reasonable price, served quickly, and in a decent atmosphere. If this robot can provide that, it'll succeed. I don't see that it can satisfy the second and third criteria. If they get that down, and the cost of the robot isn't higher than a staffed and equipped kitchen they'll succeed.
