In case of any natural disaster, the initial hours are very important to save lives. However, often times due to the nature of the disaster (forest fire, earthquake, hurricane,or flood), it can be difficult for search-and-rescue and humanitarian aid missions to reach and get immediate help to those in need.

The need for efficient, rapid, resilient transportation for disaster assistance is what led Hyundai to develop the first-ever vehicle with moveable legs. Elevate is the first Ultimate Mobility Vehicle (UMV), blending technology found in electric cars and robots, which allows it to traverse terrain beyond the limitations of even the most capable off-road vehicle.

The Elevate concept is based on a modular EV platform with the capability to switch out different bodies for specific situations. The robotic leg architecture has five degrees of freedom plus wheel hub propulsion motors and is enabled by the latest in electric actuator technology. This design is uniquely capable of both mammalian and reptilian walking gaits, allowing it to move in any direction.

The legs also fold up into a stowed drive-mode, where power to the joints is cut, and the use of an integrated passive suspension system maximises battery efficiency. This allows Elevate to drive at highway speeds just like any other vehicle. But no other can climb a five foot wall, step over a five foot gap, walk over diverse terrain, and achieve a 15 foot wide track width, all while keeping its body and passengers completely level. The combination of wheeled motion with articulating legs provides a new paradigm of mobility by enabling faster walking speeds, unique dynamic driving postures and torsional control at the end of each leg.

Inside the Elevate, passengers would experience a vehicle fully engineered to tackle the roughest terrain comfortably. Engineering enhancements include:

  • Robotic legs with five degrees of freedom plus in-wheel propulsion
  • Ability to walk in mammalian and reptilian style gaits for omni-directional motion
  • Capable of climbing a five foot vertical wall
  • Step over a five foot gap
  • Non-back drivable motors enable the legs to lock in any position
  • Modular electric vehicle platform

John Suh, Vice President and Head of Hyundai Cradle, said, “When a tsunami or earthquake hits, current rescue vehicles can only deliver first responders to the edge of the debris field. They have to go the rest of the way by foot. Elevate can drive to the scene and climb right over flood debris or crumbled concrete. This technology goes well beyond emergency situations.People living with disabilities worldwide that don’t have access to an ADA ramp could hail an autonomous Hyundai Elevate that could walk up to their front door, level itself, and allow their wheelchair to roll right in.The possibilities are limitless.”

David Byron, design manager, Sundberg-Ferar, said, “By combining the power of robotics with Hyundai’s latest EV technology, Elevate has the ability to take people where no car has been before, and redefine our perception of vehicular freedom. Imagine a car stranded in a snow ditch just 10 feet off the highway being able to walk or climb over the treacherous terrain, back to the road potentially saving its injured passengers –this is the future of vehicular mobility.”
