AI Trash. Here's a real XPENG Iron demo:
I sometimes wonder why don't they make more Robots that use wheels instead of legs as a method of propulsion (Or at least incorporate Wheels on the feet whenever It's necessary)
Because sure legs provide better access and mobility over rough terrain, But most robots are going to be probably deployed in urban areas or buildings where the terrain is more flat. And also considering the fact that wheels are more energy efficient than legs when traversing flat zones.
But thinking about it they can use a mix of both, incorporate wheels around the area of the feet like a roller skate so the Automata can move efficiently around flat areas, and for obstacles like rough terrain or stairs use the legs.
