Jet-Powered Humanoid Robot iRonCub3 Achieves First Controlled Flight

Trials at Genoa Airport will assess its AI-driven control of aerodynamics across complex aerial maneuvers.

The iRonCub3 humanoid robot, equipped with jet engines on its arms and back, hovers roughly 50 cm off the ground during a flight test at the Italian Institute of Technology. Suspended by safety tethers, the robot maintains a stable, upright posture as it demonstrates controlled lift using jet propulsion.

Overview

  • The Italian Institute of Technology led a two-year collaboration with the DAER Aerodynamics Laboratory at the Polytechnic of Milan and Stanford University to develop iRonCub3.
  • iRonCub3 uses four jet engines—two on its arms and two on a back-mounted jetpack—to hover to approximately 50 centimeters with stable flight control.
  • Its design incorporates a titanium spine and heat-resistant covers to withstand exhaust temperatures exceeding 700 °C during operation.
  • Advanced AI control systems and real-time aerodynamic evaluation enable the robot to manage interactions between its multibody dynamics and high-speed propulsion.
  • Future testing at Genoa Airport will provide a dedicated space for more extensive experimental campaigns to expand the robot’s aerial and terrestrial capabilities.
