Hover board: How does it work? - Tech - Mi Community

Hello Mi Fans How are You'll doing

Many of you know what a hoverboard is many have even maybe used it some may have not, but have you ever imagined how it works. How does it self balance? In this thread you will come to know how this works.

This Is how the board looks from inside(Below)

How Does the Self Balancing Board Move…

The Wheel Sensors: The wheels of the hoverboard house the electric motors themselves. They also contain a tilt and speed sensor. This detects the rpm (revolutions per minute) of the individual wheel, and sends it to the gyroscope and speed control boards, located inside the main body, right next to the wheels.

Gyroscope/Speed control board: The gyroscope and speed control boards receive the rpms(Revolution per minute) and tilt information from the sensor inside the wheels, and they, in turn, send it to the main logic board. When you calibrate your board, the gyroscopes are basically “zeroed”, as in, you’re telling the gyroscopes, “this is flat, and hence this is when the hoverboard’s tilt is at 0”.

Main Logic board: The logic board is the “brain” of your hoverboard, and it’s where the processor computes in real time the status of the board, the speed at which you’re travelling, and the relative speed and tilt of the individual wheels (because, for example, when you turn the two wheels have opposing tilts, and hence opposing rpms and motion). It also controls the power management of the board, and wether you are in“beginner mode” (thereby limiting the max speed of the board) or if the scooteris “locked”.

Battery: Battery packs for hoverboards are what keep everything powered. Without the hoverboard battery pack, it would not able to operate, balance, or move forward and backward.

So How does the Board Detect your movement?

This is most clever part of the board: the pressure pads sit on two switches each.

When you lean forward, the front switch is pushed down, and a little plastic “wall” slides in-between an infrared LED and an infrared sensor.

As long as the sensor detects the light, the logic board will “tell” the motors to be still. But when the light is interrupted (because of the switch being pushed down by your weight), the board tells the motor to spin in a particular direction.

So, for example, if you’re turning left, your foot activates the front right switch, making the right wheel spin forward, while your left foot activates the back left switch, making the left wheel spin backwards. It’s very clever.
