Japanese manufacturer Kawasaki Heavy Industries has revealed its latest concept, Corleo, a four-legged robot powered by hydrogen and equipped with artificial intelligence, designed to be ridden much like a horse. The prototype was showcased at the Osaka-Kansai Expo 2025, drawing attention for its blend of clean energy and robotic design.
“Robot horse” built for varied terrain
According to Kawasaki, Corleo is designed to operate on rough and varied terrain. The machine walks on four independent robotic legs, allowing it to move with balance and stability across different surfaces. The company states that each leg can move separately, offering a smoother ride on uneven ground.
Hydrogen engine powers electric movement
Corleo is powered by a hydrogen engine. The company has confirmed the use of a 150cc hydrogen motor that generates electricity to drive the robot’s four legs. Kawasaki describes the vehicle as an “off-road” mobility platform that uses clean energy to reduce environmental impact.
A body inspired by motorcycle design
The design of Corleo reflects influences from Kawasaki’s motorcycle division. The body has a streamlined shape made from a combination of metal and carbon materials.
The front features a head-like shield that resembles motorcycle aesthetics. Built-in lights allow for visibility during both day and night conditions.
Movement responds to the rider’s body
The robot horse also features a display panel. This heads-up display (HUD) shows information such as hydrogen levels, navigation, and movement stability, including how the rider’s weight is distributed.
According to the company, Corleo does not use traditional control buttons. Instead, it reacts to the rider’s body movements, adjusting its steps when the rider shifts their center of gravity.
Built-in safety features and jumping ability
Rubber “hooves” on its legs help the machine maintain grip on both hard and soft surfaces. Kawasaki notes that Corleo can jump over obstacles, although specific performance figures have not been disclosed.

A long-term vision for mobility
At this stage, Corleo remains a concept. Kawasaki has not released technical specifications such as speed, range, or battery life.
A company spokesperson indicated that Corleo is a long-term vision, with a potential market release by 2050. No additional details about the development timeline or commercial use have been confirmed.
Combining robotics and clean energy
The unveiling of Corleo reflects Kawasaki’s growing focus on robotics and sustainable mobility. The company has previously worked on industrial robots and motorcycles but has now combined elements of both to explore new forms of personal transport.
As of now, Corleo remains a vision of the future, looking at how hydrogen power and intelligent systems might shape mobility in the years to come.
