Humanoid robots have largely been caught with strolling, grabbing, or at greatest, tripping by impediment programs. However the Italian Institute of Know-how (IIT) in Genoa smashed that restrict with iRonCub3, the world’s first jet-powered humanoid robotic to nail managed flight.
Hovering 50 centimeters off the bottom, this 70-kilogram engineering marvel mixes a human-like form with sky-high expertise, hitting a milestone straight out of a sci-fi flick. iRonCub3 is the third tackle IIT’s iCub platform, a kid-sized humanoid constructed for teleoperation. This time, it’s packing 4 microjet generators—two on the arms, two on a backpack-style jetpack—kicking out over 1,000 newtons of thrust.

Daniele Pucci, who leads IIT’s Synthetic and Mechanical Intelligence (AMI) Lab, lays out the problem: “This analysis is radically totally different from conventional humanoid robotics and compelled us to make a considerable leap ahead with respect to the state-of-the-art. Thermodynamics performs a pivotal function—the emission gases from the generators attain 700°C and circulate at almost the velocity of sound.” To deal with that fiery ordeal, the workforce gave iRonCub3 a titanium backbone and heat-shield covers, letting it shrug off exhaust temps as much as 800°C with out turning right into a molten mess.
Retaining a humanoid regular within the air isn’t any cakewalk. Drones lean on symmetry and ease, however iRonCub3’s lengthy body and shifting limbs shift its steadiness with each transfer. Antonello Paolino, the research’s lead creator and a PhD scholar at IIT and Naples College, says, “Our fashions embody neural networks skilled on simulated and experimental knowledge and are built-in into the robotic’s management structure to ensure steady flight.”
The crew cooked up cutting-edge management algorithms with constrained Quadratic Programming, backed by Lyapunov evaluation, to juggle sluggish joint motors with the zippy jet generators. Wind tunnel runs on the Polytechnic of Milan and AI-powered aero fashions from Stanford College fine-tuned its hover expertise, even in windy bursts.
Constructing iRonCub3 meant a complete overhaul of the iCub’s blueprint. The workforce used PTC Creo to whip up a CAD mannequin, consistently tweaked with real-world check knowledge. A semi-auto URDF course of turned that into kinematic and dynamic fashions for planning and sims. At 70 kilograms, it’s a beefier leap from previous variations, but its jets carry it off with pinpoint accuracy. Early trials in IIT’s indoor lab labored like a appeal, with iRonCub3 holding regular throughout quick hovers. Subsequent up, they’re gearing to stretch limits at a particular flight zone at Genoa Airport, teaming with Aeroporto di Genova to roll out safety-checked, bolder strikes.
