Why the 'Hoverboard' Scooter Is So Fly

Why the 'Hoverboard' Scooter Is So Fly

Some call them hoverboards; others call them smart or self-balancing scooters. But whatever you call the two-wheeled motorized vehicles you've probably seen rolling over sidewalks of late, one thing is certain: These futuristic gadgets are pretty cool. And the physics & mechanics that make them go are cool, too.

Unlike true hoverboards, which float above the ground using magnetic levitation technologies, smart scooters have two wheels that roll over the ground. These small vehicles lack handlebars, making them trickier to operate than Segways, which have a bar for riders to hold onto that extends from the footboard to arm height.

To stay balanced on a smart scooter, you must control the movement of the device using just your feet. To move forward, you lean forward, pushing down with your toes. To move backward, you lean backward, pushing down with your heels. Turning is a bit more complicated (but more on that later). [Gift Ideas for Kids: Best Educational Toys & Games of 2015]

p> But what actually makes a "hoverboard" go? It starts with the wheels, according to the folks at BestElectricHoverboard.com. Each of the board's wheels contains a motor, as well as sensors that detect the tilt of the board & its speed. These sensors, which are activated by your weight on the board, send the information they gather to a control board & a gyroscope (a device that helps the scooter orient itself & remain stable), located inside the foot platform.

Information approximately the tilt of the board & its speed is then passed along to the scooter's "brain," or main logic board. This small computer processes all of the information from the vehicle's control board & gyroscopes, & then sends data back to the motors, telling them how swift to turn the wheels & in which direction to turn them.

To imagine how this process works, picture yourself trying to move forward while standing on one of these vehicles. When you press your toes down & lean forward, this movement is picked up by the sensors. Then, it's translated by the control board & gyroscopes & is sent to the logic board, which then tells the motors to move the wheels forward at a speed that will "keep up" with your forward-leaning body & keep you from falling flat on your face. To turn right, you would lean forward on your left foot & backward on your right foot. These movements would make the left wheel move forward & the right wheel move backward, turning the whole board toward the right.
