Hoverboards

1.Presentation:

The Hoverboard is the evolution of the skateboard, it helps you move on two wheels powered with batteries, it’s some sort of scooter, a plank equipped by a gyroscope in order to find balance easily.

3. Composition of a hoverboard:

A hoverboard is composed of various parts which are listed below:

  • A steel frame
  • Two gyroscopes
  • Two infrared detectors
  • Tow electrical engines
  • Two inclination speed captors
  • Charging Port
  • A batterie
  • Some LED lights
  • Some pressure pads
  • Coque made of plastic

4. How does it work ?

The wheels on the hoverboard has within them the electrical engines, they also contain an inclination speed captor, this allows the detection of the speed rotation (tour par minute) of each single wheel, the captor sends the speed rotation to the speed control gyroscope (panels situated inside of the principal body, just next to the wheels.

The Gyroscopes (Speed panel control) receive the RWE’s(report/weight/Engine) and the information about the inclination of the captor inside the wheels, which also send this information to the logical cards.

When you caliber your plank, the gyroscopes are automatically back to zero

The logical card of the plank is the brain and core of your hoverboard, the processor inside this card calculate the state of the logical circuit in real time, the speed of your movements, and the relative speed, of your wheels’ single inclination, it also controls the management of the card’s alimentation.

The batterie is 36Volts (V), and 4400 Mega milliamperhour (mAh).

5. How does it detect movements ?

As long as the captor detects the light, the logical card will obligate the engine to function. But when the light is interrupted (because it doesn’t detect any weight) the hoverboard will stop, the logical card will indicate to the engine to turn to a particular direction depending on where you put the pressure with your weight, thus, for example, your foot will action the right front interrupter, which makes the right wheel rotate to the front, whereas your left foot will action the back left interrupter, which makes the left wheel rotate to the back ; this is a very intelligent system.

6. Conclusion:

Because of their little wheels and their inexistent suspension, the hoverboards are not very practical outside, road bumps, uneven pavements, and even small pebbles in the roads may cause you to fall off your hoverboard.

Their wheels will have to be updated to bigger ones, or add some sort of suspension, but this might result in two problems, because of the way their logical cards function, bigger wheels will need much more power to produce the necessary couple to propulsion. Adding a suspension is a very complex problem because the captors need a constant stability in order to maintain balance of the pilot.

The platforms where the pilot puts his feet, need a fixed axe, in the opposite case, a pressure around will result in a very unsteady movement. The majority of these problems come from batteries in a way or another, which results in batteries running out of power very quickly.
