World’s first humanoid robot walks carrying drone that drives, flies

Caltech, in collaboration with the Technology Innovation Institute (TII) in Abu Dhabi, has developed the world’s first multi-robot system called the X1 System, which integrates a humanoid robot with a transforming drone capable of walking, flying, and driving. This innovative system combines a modified Unitree G1 humanoid robot that can carry heavy loads with the M4 multimodal robot, which can be deployed from the humanoid’s back to fly over obstacles or transform into a wheeled vehicle for driving. The X1 System is designed to autonomously navigate complex terrains and perform real-world missions such as emergency response and urban navigation without human control. The development involved multiple teams, including Caltech’s Center for Autonomous Systems and Technologies (CAST), TII, and Northeastern University, focusing on locomotion control, autonomy, onboard computing, and morphing mechanics. During a demonstration at Caltech’s Pasadena campus, the humanoid robot successfully launched the M4 drone, which flew over obstacles,
