How Does a Self Balancing Scooter Work? Here's How!

Self balancing scooters are the “in thing” right now and everyone’s got one. You’ve probably just bought your own Drift Scooter self balancing scooter and are having plenty of fun with it.

However, leaving aside all the fun and hype surrounding this crazy technological invention, do you have any idea how a self balancing scooter actually works?

Well, we thought you might want to know. So, we prepared a blog for you with all the basic details behind how a self balancing scooter actually gets moving.

The components involved

These are the primary components involved in the construction and functioning of a self balancing scooter:

The functions

All the components mentioned above have a role to play in the functioning of a self balancing scooter. However, we’ll just take a look at the most important ones. To begin with, the wheels of the self balancing scooter hold the electric motors, along with the tilt and speed sensors. The tilt and speed sensors help detect the RPM (Revolutions Per Minute) of each wheel. The detected readings are then sent to the gyroscopes and the speed control boards, which are located in the primary frame or body, right near the wheels.

Once the gyroscopes and the speed control boards receive the readings from the sensors, they forward it to the logic board.

Initially, the logic board calibrates the gyroscopes with a 0 reading, which basically means that the self balancing scooter is in a flat position. The calibration can be changed using the self balancing scooter’s remote.

The logic board is where all the important action happens. Here, the processor carries out several computations that determine the status of the board. This includes data about travel speed, the relative speed of the wheels, and the tilt position of the wheels.

The logic board is also responsible for power management. For instance, if you’re in beginner mode, the logic board will automatically limit the maximum speed by reducing the power supply.

Finally, you have the battery pack, which is what supplies the needed power to your self balancing scooter. Battery packs tend to vary in capacity based on the model you purchase.

The movement

So, how does the self balancing scooter move? Well, this is where the pressure pads come in. For example, when you lean forward, the switch in the front gets pressed down. Then, a plastic wall of sorts inserts itself between the infra-red sensor and the infrared LED.

Once the sensors detect the light, the logic board sends out a message to the motors asking them to remain still. But, when the light gets disturbed due to the pressing, the board informs the motors to start spinning.

The balancing

For the balancing part, the tilt sensors inform the gyroscopes on how far you are leaning. The gyroscopes then send this information to the logic board. So, depending on how forward you lean, the logic board determines how fast the motors in the wheels spin. Basically, it is your weight distribution and center of gravity that ultimately control the speed of thee self balancing scooter.
