ATLAS–the totally incredible Boston Dynamics robot that strikes love and fear into the hearts of all who witness its humanoid stride–is having a tough time lately. Last month it broke its ankle during its first live demonstration, and now it crumples when trying to walk through some minor debris. This footage, taken by a team from Florida’s Institute for Human and Machine Cognition, shows the rescue ‘bot flailing and falling over a piece of wood while trying to traverse the rubble. We once thought it was untrippable, too.
