OSAKA, Japan – April 5, 2025 — Kawasaki Heavy Industries has officially introduced CORLEO, a hydrogen-powered, four-legged robotic mobility vehicle designed to carry human riders. The unveiling took place at the highly anticipated Osaka-Kansai Expo 2025, positioning CORLEO at the intersection of clean energy, advanced robotics, and futuristic transport.
Reimagining Personal Mobility with Robotics
CORLEO is a quadrupedal robot designed to replicate the gait and posture of a horse. Unlike wheeled transport, CORLEO walks using four mechanical limbs, allowing it to traverse varied terrain more naturally. Its biomimetic engineering brings an animal-like presence to robotic mobility, offering a unique blend of functionality and familiarity.
Sustainable Power with Hydrogen Fuel
What sets CORLEO apart is its hydrogen-powered propulsion system. As the world shifts toward carbon-neutral technologies, Kawasaki’s use of hydrogen fuel emphasizes its commitment to eco-friendly robotic transportation. The system operates quietly with zero tailpipe emissions, making it suitable for use in public or sensitive environments.
Advantages of the CORLEO Robotic Vehicle
- Environmentally conscious: Uses hydrogen fuel for cleaner energy.
- Adaptive mobility: Four-legged locomotion handles uneven terrain better than wheels.
- Human-centered design: Accommodates a rider in a saddle-like seat.
- Low noise output: Suitable for patrol, tourism, or exhibition settings.
This futuristic robotic horse showcases how robotics and sustainability can work in harmony to redefine personal transport.
This is mind-blowing.

Challenges Facing Adoption
Despite its innovation, CORLEO comes with limitations. The global hydrogen refueling infrastructure is still in early stages, potentially limiting operational range and accessibility. Additionally, its payload capacity and speed may not yet meet industrial or commercial transport needs compared to more conventional utility vehicles.
Comparing CORLEO to Traditional and Robotic Systems
CORLEO differs sharply from wheeled or tracked robots due to its quadrupedal build. This allows smoother movement over rough ground but may sacrifice speed and maneuverability. Unlike other rideable robots, CORLEO focuses on human-riding applications, blending animal-inspired design with futuristic tech.
A Bold Step Toward Robotic Mobility Innovation
The introduction of CORLEO at Expo 2025 highlights Kawasaki’s ambition in advanced robotics and hydrogen fuel systems. While the vehicle remains an early prototype, its public debut sparks interest in next-generation mobility technologies. If supported by infrastructure and improved performance, CORLEO could inspire a new category of clean, adaptable robotic transport.
A Symbol of Sustainable Tech at Expo 2025
Kawasaki’s CORLEO is more than just an expo showpiece — it represents a new vision for green, rideable robotics. As audiences at the Osaka-Kansai Expo 2025 engage with the robotic steed, the potential for hydrogen-powered mobility and lifelike machines takes a significant stride forward.
