Meet X1, a unique hybrid robot from Caltech that combines the capabilities of a humanoid, a drone, and a vehicle. This machine looks like it came straight out of a sci-fi movie—part robot, part Transformer.
Developed by researchers at the California Institute of Technology, X1 merges two distinct machines: the Chinese-made Unitree G1 humanoid robot and Caltech’s M4 drone.
The humanoid robot serves as a carrier platform, walking on two legs, climbing stairs, and even opening doors with its hands. Upon reaching open space, it leans forward to create a launchpad for the M4 drone.
"The M4 can take off, fly independently, land, and then switch to wheeled mode to continue moving on the ground."
Caltech’s team spent three years integrating these different modes of movement into a cohesive system. X1 demonstrates rare versatility by traveling across land and through the air—though it cannot operate underwater.
X1 pushes the boundaries of robotics by integrating walking, flying, and rolling capabilities into one adaptable hybrid system, showcasing innovation in both humanoid and drone technologies.
