2. 3 Calibration

If your scooter seems to pull to the left or right, you may need to recalibrate its sensors. The process requires two levels, available
at any hardware store. Many smartphones have free "bubble level" apps as well.
Step 1: Power off the scooter.
Step 2: Place each level parallel with the wheel touching the inside of the wheel base.
Step 3: Rotate the scooter until both levels on each wheel base are level. If you do not have a level, make
sure both platforms are equal with each other and level to the ground as best as possible.
Step 4: While keeping the scooter level, hold the power button down. The scooter will make the normal power on tone. Wait 3
seconds and you will hear a single beep. Release the power button. Front LEDs will begin flashing. Power the scooter off.
Step 5: Power on again. The scooter should now be calibrated. If the scooter is still not
calibrated correctly, go to step 1 and begin making minor adjustments.

2. 4 Operating principal

• Self Balancing Electric Scooter uses Dynamic equilibrium, using internal gyroscope and acceleration sensors. The status
of the electric scooter is controlled by the center-of gravity. It is adjusted by motor which is controlled by the servo control
system. When you lean forward, it will sense your actions to accelerate. When you need to turn, slow it down and move your
foot forwards or backwards then the center-of gravity of the body moves left or right therefore the scooter can sense moving
left or right.
• Self Balancing Electric Scooter has inertial dynamic stabilization system, so it can keep anterior-posterior balance but cannot
guarantee the left and right. So when turning, the scooter needs to be operated slowing, otherwise, you may get injured.
