One of many robotics tasks that I’ve been most enthusiastic about for years now’s iRonCub, from Daniele Pucci’s Artificial and Mechanical Intelligence Lab on the Italian Institute of Know-how (IIT) in Genoa, Italy. Since 2017, Pucci has been growing a jet-propulsion system that may allow an iCub robotic (initially designed in 2004 to be the approximate form and dimension of a 5-year-old youngster) to fly like Iron Man.
Over the summer season, after practically 10 years of growth, iRonCub3 achieved lift-off and stable flight for the first time, with its 4 jet engines lifting it 50 centimeters off the bottom for a number of seconds. The long-term imaginative and prescient is for iRonCub (or a robotic prefer it) to function as a disaster response platform, Pucci tells us. In an emergency scenario like a flood or a fireplace, iRonCub might shortly get to a location with out worrying about obstacles, after which on touchdown, begin strolling for energy efficiency whereas utilizing its palms and arms to maneuver particles and open doorways. “We consider in contributing to one thing distinctive sooner or later,” says Pucci. “We have now to discover new issues, and that is wild territory on the scientific degree.”
Clearly, this idea for iRonCub and the sensible experimentation hooked up to it’s actually cool. However coolness in and of itself is normally not sufficient of a purpose to construct a robotic, particularly a robotic that’s a (presumably quite costly) multi-year mission involving a bunch of robotics college students, so let’s get into just a little extra element about why a flying robotic child is definitely one thing that the world wants.

Getting a humanoid robotic to do that form of factor is kind of a problem. Collectively, the jet generators mounted to iRonCub’s again and arms can generate over 1000 N of thrust, however as a result of it takes time for the engines to spool up or down, management has to return from the robotic itself because it strikes its arm-engines to keep up stability.
“What is just not seen from the video,” Pucci tells us, “is that the exhaust gasoline from the generators is at 800 °C and nearly supersonic velocity. We have now to know the best way to generate trajectories in an effort to keep away from the truth that the cones of emission gases had been impacting the robotic.”
Even when the exhaust doesn’t find yourself melting the robotic, there are nonetheless aerodynamic forces concerned which have till this level actually not been a consideration for humanoid robots in any respect—in June, Pucci’s group published a paper in Nature Engineering Communications, providing a “complete method to mannequin and management aerodynamic forces [for humanoid robots] utilizing classical and studying methods.”

Whether or not or not you’re on board with Pucci’s future imaginative and prescient for iRonCub as a disaster-response platform, derivatives of present analysis may be instantly utilized past flying humanoid robots. The algorithms for thrust estimation can be utilized with different flying platforms that depend on directed thrust, like eVTOL plane. Aerodynamic compensation is related for humanoid robots even when they’re not airborne, if we count on them to have the ability to operate when it’s windy outdoors.
Extra shocking, Pucci describes a current collaboration with an industrial firm growing a brand new pneumatic gripper. “At a sure level, we needed to do power estimation for controlling the gripper, and we realized that the dynamics appeared actually just like these of the jet generators, and so we had been ready to make use of the identical instruments for gripper management. That was an ‘ah-ha’ second for us: first you do one thing loopy, however you then construct the instruments and strategies, after which you possibly can really use these instruments in an industrial situation. That’s the best way to drive innovation.”
What’s Subsequent for iRonCub: Attracting Expertise and Future Enhancements
There’s yet one more necessary purpose to be doing this, he says: “It’s actually cool.” In observe, a very cool flagship mission like iRonCub not solely attracts expertise to Pucci’s lab, but in addition retains college students and researchers passionate and engaged. I noticed this firsthand once I visited IIT final 12 months, the place I acquired an analogous vibe to watching the DARPA Robotics Challenge and DARPA SubT—when folks know they’re engaged on one thing actually cool, there’s this tangible, pervasive, and immersive buzzing pleasure that comes by. It’s tasks like iRonCub that may get college students to like robotics.
Within the close to future, a brand new jetpack with an added diploma of freedom will make yaw management of iRonCub simpler, and Pucci would additionally like so as to add wings for extra environment friendly long-distance flight. However the logistics of testing the robotic are getting extra difficult—there’s solely to this point that the group can go along with their present take a look at stand (which is on the roof of their constructing), and future progress will possible require coordinating with the Genoa airport.
It’s not going to be straightforward, however as Pucci makes clear, “This isn’t a joke. It’s one thing that we consider in. And that feeling of doing one thing distinctive, or presumably historic, one thing that’s going to be remembered—that’s one thing that’s saved us motivated. And we’re simply getting began.”
