iRonCub3
Shivi JainHumanoids flying before humans
The future of humanoid robotics just took flight—both literally and metaphorically. Meet iRonCub3, the world’s first flying humanoid robot, and a project that extends the boundaries of what robots can do.
The Italian Institute of technology have created this marvel- a combined effort by PhD students and researchers alike, robotics engineers, AI specialists, and aerodynamics experts. They collaborated with researchers at Stanford, and while it wasn’t a solo student project, it was heavily student-driven in a major institute which makes the whole thing even more impressive. What’s beautiful is that since 2009 this has been happening in Italy, and students here are actually promoted to do this by the government’s support itself.
Earlier, since 2009 the researchers at there had developed iCub, a child-sized humanoid robot designed to mimic a 3–5‑year‑old child, iCub can crawl, grasp objects, express emotions, and balance. This wasn’t limited to just Italy however, because it sparked a whole community- making it a staple across ~30 labs worldwide! iRoncub3 is built as an evolution of iCub, what’s new is the researchers added four micro-jet turbines, two on each arm and two on it’s back- like a baby Ironman with AI brains! It generates over 1,000 N of thrust, enabling it to hover about 50 cm off the ground. That sound less? For comparison- it’s like trying to fly a Jenga tower with mini rockets underneath it, and you have to make sure the tower doesn’t fall over or catch fire.
Why is it such a big deal?
Because until now, robots could walk, talk, run and maybe fall down the stairs- but not fly.
iRonCub3 changes that. Most flying machines use rotors like drones for easy stability. But jets are: Hotter, Faster, Harder to control and HIGHLY SENSITIVE to posture. So keeping a humanoid shape steady in the air, using fast-reacting AI trained for flight physics, is a first-of-its-kind achievement. It combines the best of both worlds, humanoid robotics and aerial drones! It opens up future robots that can walk and fly to hard-to-reach areas.
And– How it works
Much like the way planes work, the micro-turbines suck in air and compress-mix it with fuel, igniting it to produce a very strong thrust, lifting it into the air
But the real fun starts with this- how are such powerful jet engines kept stable? That’s where the AI beautifully steps in. Every mili-second, it’s sensing it’s surroundings, and thinking on that basis- hence calculating the amount of thrust required to hold balance.
It’s like juggling fireballs while standing on one foot—the AI must continuously adjust the robot’s limbs and jets to counteract gravity, air resistance, and motion.
When the Wright brothers flew their plane in 1903, it stayed in the air for just 12 seconds and traveled 36 meters. It didn’t look like much—until it changed the world.
iRonCub3’s 50 cm hover might seem small—but it’s the first-ever jet-powered lift-off by a humanoid robot. Just like the Wright brothers, it’s the first step toward a future where robots can fly where humans can’t.
