Robot Brief

CORLEO is an innovative, hydrogen-powered, four-legged robotic off-road personal mobility vehicle developed by Kawasaki Heavy Industries, unveiled as a futuristic concept leading up to the Expo 2025 Osaka-Kansai. Inspired by the agility and stability of wolves, CORLEO combines the terrains handling of legged robots with the thrill and simplicity of riding a motorbike, designed especially for mountainous and rough terrains where wheels struggle. It features four independently articulated robotic legs equipped with adaptive hooves that provide excellent grip and shock absorption on diverse surfaces such as rocky ground, grasslands, rubble, and even near-vertical slopes. The robot is powered by a compact 150cc hydrogen engine that acts as a generator supplying electricity to motors at each leg, aligning with Kawasaki's commitment to carbon-neutral and next-generation mobility solutions. The rider mounts CORLEO similarly to horseback riding, controlling it intuitively by shifting body weight detected by sensors, supported by AI for balance and navigation assistance. The vehicle also features a heads-up display with useful ride information for a safe and engaging experience. CORLEO is currently a concept envisioned for commercial deployment in about 25 years, reflecting a long-term futuristic vision in personal mobility.

Use Cases

  • All-Terrain Mobility: Four-legged robot capable of traversing rough, uneven, and sloped terrains inaccessible to wheeled vehicles.
  • Hydrogen-Powered Propulsion: Uses a 150cc hydrogen engine as a generator to supply electricity to individual leg motors, offering clean energy with water as emission.
  • Adaptive Hoof Design: Rubber split hooves absorb shocks and provide non-slip grip on varied surfaces including rocks, rubble, and grasslands.
  • Intuitive Rider Control: Responds to rider’s weight shifts and movement rather than traditional controls, making it accessible and stable for beginners.
  • AI-Assisted Real-Time Balance: Artificial intelligence systems dynamically adjust gait and posture for stability during walking, running, climbing, and descending.
  • Informative Heads-Up Display: Shows hydrogen fuel levels, route information, center of gravity, and terrain navigation markers to assist the rider.
  • Shock Absorption and Posture Maintenance: Independent rear leg suspension and adjustable stirrup length enable shock absorption and optimal rider posture.
  • Night Riding Support: Projects markers onto the road surface to indicate the path ahead in low-light conditions.

Intro

CORLEO is a four-legged, hydrogen-fueled robotic vehicle designed for off-road personal mobility akin to horseback riding in mountainous environments. Each leg integrates electric drive units powered by a 150cc hydrogen engine generator. The legs end in split rubber hooves engineered to absorb shocks and grip challenging surfaces. The rear legs employ independent swingarm mechanisms inspired by motorcycle suspension for enhanced stability and shock absorption. Riders mount the machine similar to a horse, controlling it through body-weight shifts detected by pressure sensors on foot plates and handlebars. Artificial intelligence and sensor fusion maintain real-time balance and gait adjustment, enabling movements like walking, running, jumping, and adjustable postures on inclines and uneven terrain. A heads-up display presents critical information such as hydrogen levels, navigation data, and rider posture feedback. With the ability to project visual guides onto the terrain at night, CORLEO supports safe riding in diverse lighting conditions. Constructed from metal and carbon materials, it embodies Kawasaki’s expertise in motorcycles and robotics.

Connectivity

  • Integrated sensor data network for real-time balance and gait control.
  • Heads-up display with live feedback on vehicle state and environmental conditions.
  • Interfaces for monitoring hydrogen fuel levels and navigational info.

Capabilities

  • Hydrogen Fuel Cell Propulsion: Clean, efficient power generation with a 150cc engine producing electricity on-board.
  • Independent 4-Leg Drive: Each leg moves autonomously, adapting to terrain challenges dynamically.
  • AI-Based Balance and Gait Control: Real-time adjustments using machine learning to maintain rider stability and smooth motion.
  • Adaptive Hoof Design: Rubber hooves with left-right divided structure provide grip and shock absorption on various surfaces.
  • Terrain Adaptability: Capable of climbing slopes, stepping over obstacles, and traversing rough, rocky, and unstable ground.
  • User-Centric Control: Rider input through natural weight shifts allows intuitive control, eliminating need for traditional controls.
  • Night Navigation Assistance: Road surface projection helps guide riders safely during low visibility.
  • Comfort-Oriented Suspension: Rear leg swingarm mechanism enhances shock absorption and rider comfort.
