The video you’ll watch three times: this humanoid robot can walk, fly, roll… and transform to fly!

The Versatile Hybrid Robot X1 from Caltech

X1 is a unique hybrid robot developed by the California Institute of Technology (Caltech), combining humanoid, drone, and vehicle features into one machine. It can walk, fly, and roll, representing a breakthrough in robotic mobility.

Design and Components

The robot merges two distinct machines:

Unitree G1: A humanoid robot made in China, capable of walking on two legs, climbing stairs, and opening doors.
Caltech’s M4 drone: A flying robot that, upon landing, rotates its arms and converts its circular propeller guards into wheels, transforming into a compact rolling vehicle.

Functionality and Movement

When combined, the G1 serves as a walking platform with mechanical wings on its back, carrying the M4 drone. Upon reaching open space, the humanoid leans forward to create a launchpad, allowing the drone to take off and operate independently. The M4 drone can then fly, land, and switch modes to roll across the ground.

“It took Caltech’s team three years to bring all these modes of movement together into a single, cohesive system.”

X1's ability to travel both on land and in the air, though not underwater, offers rare versatility in robotics.

Summary

X1 is an innovative hybrid robot blending humanoid and drone capabilities, enabling it to walk, fly, and roll seamlessly, showcasing advanced multifunctional mobility in robotics.
