I think you make a good point. I'm not sure why you're getting downvoted. A very common mistake from engineers who become entrepreneurs is to not understand the markets they're trying to enter, or even their customers. They think they have a cool tech solution and everybody will see the world like they do. Then they launch and find out they have a novelty that loses money.

I don't know the specifics of this business, but trying to build a robot for X without understanding X is a great way to lose money.
