Kawasaki Unveils CORLEO, A Hydrogen-Powered, Four-Legged Mobility Vehicle & 2 Other Concepts

Ahead of the upcoming Osaka-Kansai Expo 2025—set to be held from April 13 to October 13, 2025 (yes, six months!) in Japan—Kawasaki Heavy Industries Group revealed three concept products at a showcase event of the Expo, which focuses on the “Future of Mobility.”

Kawasaki is a Japanese public multinational corporation that manufactures motorcycles, engines, heavy equipment, aerospace and defense equipment, and more. So, naturally, one would expect its concept prototypes to be something extraordinary, especially since it’s set to make a mark at a six-month-long exposition—and the company did not disappoint.  

Concept 01: CORLEO

Kawasaki introduced a new category of personal mobility that combines the functions of an off-road motorcycle with a fun-to-ride feel.

Kawasaki’s Concept 01: CORLEO is a hydrogen-powered, four-legged robot that gains its inspiration from animals such as wolves, deer, and panthers, i.e., sleek movers. Yet, humans can ride it like a horse (have you heard of people riding wolves, deer, or panthers?).

It comes with the handling and stability of Kawasaki’s motorcycles, offers all-terrain capability, and preserves “the joy of riding,” as per the company.

“The vehicle continually monitors the rider’s movements to achieve a reassuring sense of unity between human and machine.”


The robot’s rear leg can move independently from the front leg’s unit, allowing riders to maintain leveled postures when climbing stairs, which ensures they’re looking at the path ahead instead of upward. These legs can even absorb shocks while walking and running.

At the end of these legs sit hooves that sport a left-right divided structure made of rubber, which is slip-resistant and can adapt well to irregular surfaces, including grasslands, rocky areas, and rubble fields.

The vehicle, with drive units installed in each of the four legs, is powered by a 150cc hydrogen engine, where the hydrogen is supplied from a canister mounted at the rear. It comes with an instrument panel that displays the hydrogen level, route to the summit, center of gravity position, and other information. This includes a feature that assists riders at night by projecting markers onto the road surface in front of them, marking the path ahead.


Kawasaki also posted a video showing off the robot’s capabilities.  

Concept 02: ALICE SYSTEM

Kawasaki’s ALICE SYSTEM is a system that combines Kawasaki's land, sea, and air mobility technologies to allow people around the world to enjoy movement freely and comfortably.

At least, that’s the idea behind Kawasaki’s Concept 02: ALICE SYSTEM.

FYI, ALICE is an acronym for Accessible Linkages for Innovative and Comfortable Experiences.

The concept is designed to become the transportation system of the future, which would allow “anyone anywhere to reach their destination in the comfort of a personal cabin.”


All users need to do is input key information—destination, number of passengers, etc.—into the ALICE app to receive multiple automatically generated travel options. The app will provide them with a plan that centers around their preferences or a plan that ensures they reach their destination ASAP. Plans can be modified by users.

Once a user selects their plan, an ALICE Cabin is sent to them. Users sit inside the Cabin while it’s automatically transferred between the hydrogen-powered ALICE Car, ALICE Rail, ALICE Ship, and ALICE Aircraft, delivering them to their destination.


The ALICE Cabin comes with a robotic arm-powered concierge that can assist with various tasks, such as ordering drinks, fetching devices, helping users wear coats, and more. It also features a remote communication system that allows them to communicate with other cabins, gain information through audio and text announcements, enjoy video conferencing, and more. The display is fitted on the window’s semi-transparent glass, which users can use to watch movies or even turn off to look outside.

Each Cabin accommodates a maximum of four people, and seats can be removed to create space for wheelchair users.


Essentially, it consists of an app that allows users to plan their journey, which brings them a cabin that’s automatically transferred across rail, road, water, and air, all handled by the ALICE SYSTEM. 

Concept 03: O’CUVOID

Kawasaki’s third concept comes as the company pushes for a hydrogen-powered society.

Concept 03: O’CUVOID is a power generator that combines a hydrogen engine used in Kawasaki motorcycles with a generator and inverter.


O’CUVOID offers users an affordable power generator that doesn’t emit carbon dioxide. It comes with a communications system that allows users to monitor the status of each component. This includes maintenance and failure checks, at which point any unit can be swapped out for another, reducing system downtime.

Moreover, each O’CUVOID can be connected to create a combined power system that can be deployed for a wide range of purposes, including powering large vehicles and generating energy for homes.


In the last few days, the robotics sector has taken some major leaps (no pun intended), with advancements in driverless trucks, tiny flying robots, and tiny healthcare-focused robots, among others.
