Assuming it's true that it just stumbled and the "incident" part is a nothingburger, the headline as written is still literally accurate. It's also still worth discussing: was the robot appropriately cautious of its surroundings when it performed that maneuver? Perhaps it could not have been aware enough to avoid all potential damage and that could be another discussion.
At which point does a "thing that moves by itself" like a Railway crossing and a thing that keeps itself in an upright position become a robot that needs to determine if an action can lead to physical harm on something else or itself?
I do not thing this thing can be cautious because it is a remote controlled car with 2 legs and everything the "AI" part is doing build down to keeping balance and locating the position that it hardcoded needs to grab.
Or in other words there is an operator, like with an RC car or a real car.
