The French firm Rollkers SAS from Dijon took part in the CES, a global consumer electronics and consumer technology tradeshow that takes place every January in Las Vegas, Nevada (USA).
According to the inventor Paul Chavand, Rollkers look like skates but are not skates. They give the feeling to walk faster, on a travelator. The Rollkers amplify the movement of walking: half steps, twice as fast.
With 2,8kg each, Rollkers are quite heavy! They would recharge on their own through walking.
