SUMMARY:

 

iRonCub3 is a jet‑powered flying humanoid robot developed by the Italian Institute of Technology (IIT) as the world’s first humanoid capable of controlled flight using miniaturized jet engines. Built on the latest generation of the iCub3 humanoid platform, iRonCub3 integrates four jet turbines—two mounted on the arms and two on a backpack module—to achieve vertical lift and mid‑air stabilization. It successfully performed its first flight in 2025, hovering approximately 50 cm above the ground while maintaining balance. 

 

Designed for disaster response, extreme‑environment exploration, and multi‑modal mobility research, iRonCub3 represents a major milestone in aerial humanoid robotics.

 

EDITORIAL:

 

iRonCub3 is one of the most ambitious robotics projects of the decade: a humanoid robot designed not just to walk or manipulate objects, but to fly. Built on the iCub lineage—a platform originally created to match the size and proportions of a 5‑year‑old child—iRonCub3 extends the concept of embodied AI into the domain of aerial mobility.

 

The engineering challenge is extraordinary. Unlike drones, which are symmetric and optimized for flight, iRonCub3 must stabilize a human‑shaped body with uneven mass distribution, articulated limbs, and shifting center of gravity. IIT’s researchers solved this through a combination of jet‑thrust control, whole‑body dynamics, and real‑time state estimation, allowing the robot to maintain stable hover despite its complex geometry. 

 

The result is a platform that blends humanoid intelligence with aerial capability, opening possibilities for search‑and‑rescue missions where ground robots cannot reach. iRonCub3 is not a consumer robot, nor a general‑purpose humanoid. It is a research‑grade flying humanoid, pushing the boundaries of what embodied AI can do in three dimensions.
