Hoverboard
What is a hoverboard?
 A hoverboard (or hover board) is a levitating board used for personal
transportation, first described in science-fiction, and made famous by
the appearance of a skateboard-like hoverboard in the film Back to the
Future Part II. Many attempts have been made to invent a functioning
hoverboard.
Idea of hoverboard  Hoverboards were first described by author M. K. Joseph in a 1967
science fiction novel.[1] In 1984, a hoverboard appeared in the shoot
'em up arcade video game SWAT, developed by Coreland and
distributed by Sega in Japan and Bally Midway in North America.[2]
 The hoverboard was popularized by the Back to the Future film
franchise, with its appearance in Back to the Future Part II (1989).[1]
During the 1990s there were rumors, fueled by the film's director
Robert Zemeckis,[3] that hoverboards were in fact real, but not
marketed because they were deemed too dangerous by parents'
groups. These rumors have been conclusively debunked.[3]
 Hoverboards have appeared in various other media since the 1990s.
For example, video games such as the beat 'em up arcade game Riding
Fight (1992), manufactured by Taito,[4] and the sports video game
AirBlade (2001), developed by Criterion Games and distributed by
Sony in Europe and Namco in North America.[5]\
WHAT ARE HOVERBOARDS MADE OF?
 Hoverboards use a variety of sensors and other components to move,
balance and function.
 Gyroscope: The most important part of a hoverboard, this component
adjusts the tilt of the platform in order to keep the rider balanced. It's
such an important piece of how a hoverboard functions that the
devices are sometimes called "gyro scooters".
 Microprocessor: These regulate the amount of power going to the
wheels.
 Battery: A lithium-ion battery stores the hoverboard's electrical power
and charge. 4 hours usually gives a full charge and provide up to 8
miles of riding
 Motor: Receives information from the logic board and powers the
wheels when you tilt.
 Infrared sensors (IR sensors): Infrared rays measures an objects
presence and distance and are used for a number of functions.
 Tilt and speed sensors: Controls the speed of the hoverboard by
measuring how quickly the wheels are turning and communicating
with the gyroscope and logic board.
 Logic board: Processes the data from various sensors and sends the
information to the motors. This provides the required movements and
directions as well as a balanced device.
 Pressure pads: This is where a rider's feet are placed. They let the logic
board know that someone is riding as well as what direction they want
to go.
 Two Wheels: These range in size according to the manufacturer. If
you're thinking of taking your board off-road, look for a board with 8inch wheels.
 Power switch: Turns the board on and off.
 Charging port: Most hoverboards come with a port for charging but
these can be bought online separately, too.
HOW DO HOVERBOARDS WORK?
MOVING FORWARD AND BACKWARD
 All the above components work together to control the power and tilt
of the hoverboards so the rider is balanced, upright and moving at a
controlled speed. But how does it work, technically-speaking?
 Each wheel has it's own gyroscope and tilt and speed sensor. When
you climb aboard and tilt your balance forward or backward, the
gyroscope tells the logic board which way to move. The logic board
sends that data to the motor, which rotates the wheels and generates
the power for you to move.
 More tilt = more speed.
STOPPING
 IR sensors and pressure pads placed below the foot platform send
data to the logic board when you're not tilting. That tells the logic
board not to run the motor so the board won't move.
TURNING
 When a rider moves the right leg ahead, the hoverboard will move the
right wheel only. This turns off the motor to the left wheel and allows
the board to turn left. For a right turn, the rider moves the left foot
ahead.
 If you want to move in circles, tilt any one leg forward.
