Italian researchers have built a humanoid robot that may one day fly like Iron Man

As robots have steadily expanded their operations out of the controlled environments of research labs and into the chaos of real-world architectural infrastructure, getting from point A to point B has become a major challenge -- take stairs, for example. In response, roboticists have developed a number of solutions, from installing rotors so that the robot can helicopter over obstacles or, in Boston Dynamics case, execute backflips that would give Simone Biles pause. And then there's Daniele Pucci, head of the Artificial and Mechanical Intelligence lab at the Italian Institute of Technology, who has taken the audacious step of strapping a fully functional jetpack akin to what Richard Browning developed onto the back of an iRonCub synthetic humanoid with hopes of eventually blasting it into the sky. You'd think we'd have learned our lesson about the dangers of building aerial humanoid robots after our first time through Age of Ultron but Pucci's team believes that such systems could one day act as first responders to the roughly 300 natural disasters that kill around 90,000 people worldwide annually. We've seen a slew of disaster response bots -- some humanoid, some not so much -- emerge from labs for more than a decade, often with varying degrees of success.
