Are there such drones without human remote control?

What would help at least me is to see this dogs actually used for something useful where they are the best solution, what I mean used in production not demos - because I can't imagine that many scenarios where are a good solution over a drone or a robot with wheels.

Yes. Definitely. autonomous flying air craft are not new. much easier compared to anything moving on the ground. object and path detections is arguably less likely to fail being less contact with terrain.

>Are there such drones without human remote control?

To be realistic. Spot (the dog) is not autonomous currently either. In fact it doesn't even use "AI", all of its movements are electrical and mechanical control theory on steroids ;)

The BD customer can integrate an AI to direct movements if desired but it's not what BD ships. BD instead offers a human operated remote control with camera system.

Any idea What is it good for?

SpaceX uses them to inspect still burning crashed spaceships (minutes post-crash).

Do they do it for PR reasons? i assume you can use drones more effectively.

Why do you think so? A drone has to be piloted the whole time, while a dog can be positioned and stay there with no further piloting or energy requirement. I also imagine that piloting a drone around hissing gas and in low vision could be problematic.

So if SpaceX needs video of the landing/crash sites then you could buy a few drones instead of a single dog. Because of possible debris and fire on the ground I also expect a drone would be better, and if teh land is clear then a drone could also be configured to land and film from the ground(because you could afford multiple ones you can have different configurations).

I might be missing something though, a scenario where an robot with legs can do better then a flying or wheeled one.

Fires, especially large hots ones, create wind and other aerodynamic instability.
