How fast do you walk? Most people walk between 4 and 6.5 kilometers per hour. But with the Moonwalkers, a pair of walking devices, you can increase your speed by up to 250 percent. These amazing devices can allow you to walk up to 11 kilometers per hour!
The Moonwalkers were invented by a company called Shift Robotics. A pair of the Moonwalkers looks like the lower part of a pair of roller skates. The walking devices can be fastened to the bottoms of regular shoes. But you don’t skate with the Moonwalkers. You can just walk with them the way you do with regular shoes.
The Moonwalkers are very special. Each Moonwalker weighs about 1.9 kilograms. The motor in it powers eight wheels. There is also a gearbox (变速箱) and a few sensors in each Moonwalker. These sensors collect data about the wearer’s walking. The gearbox then uses the data to help change the speed of the Moonwalkers. When it is necessary, the gearbox will slow down the shoes to prevent accidents. And when the wearer has to take the stairs, he or she can lock the wheels to safely go up and down the stairs.
“The Moonwalkers are the world's fastest walking shoes,” says Xunjie Zang, CEO of Shift Robotics. “You don’t need to learn how to use them, but instead they’ll learn from you.” The first batch (批次) of Moonwalkers will ship this summer. Are you looking forward to trying them out?
