Kawasaki Heavy Industries has unveiled a new type of robot named Corleo, inspired by a horse, at the Osaka-Kansai Expo 2025 showcase event in Japan. This hydrogen-powered robot with four legs is designed for humans to ride, distinguishing it from previous animal-shaped robots like Boston Dynamics' Spot. The robot is currently in the concept phase, with no functioning prototype publicly available yet. Corleo's legs are equipped with inward-facing knees and rubber hooves similar to a goat's, allowing it to navigate various terrains. Kawasaki envisions the robot carrying up to two riders through rocky cliffs, snow, forests, and streams. The design also includes an AI system for balance, navigation, and rider interaction, along with a heads-up display for important information. Powered by a 150cc engine fueled by a hydrogen fuel cell, Corleo aims to be environmentally friendly, emitting only water as a byproduct. While the robot is set to debut at the Osaka-Kansai Expo, there are no concrete plans for commercialization or detailed technical specifications available yet. Kawasaki suggests a potential launch by 2050 but has not outlined a development timeline.
