Development of A Two-Wheeled Balancing Scooter


The uniqueness of the two wheeled balancing platform has became the reason for many researcher to continue investigate this unstable nature of the system. The idea of a two wheeled balancing scooter has come in the control research world for a few years. Due to its new technology, available balancing scooter in the market is still very expensive. Looking at the benefit of this balancing platform as a human transporter, then a research to develop more reasonable price of this system is going to be conducted.
In this research, a two wheeled balancing scooter will be developed. The aim of this research is to study the most possible balancing scooter which is using less complicated system that believed can reduce the complexity of the system. Developing a less complex one but still perform a good balancing platform will help people to know and to study about this balancing platform. Mechanical structure and electronic circuit for the scooter will be designed and PD controller will be implemented in this system using 8 bit microcontroller. Output of the signal control from microcontroller then will be converted into PWM signal to drive two independent 250W DC motor. These DC motors are used to actuate two 13” of diameter scooter wheels.
The test result of the two wheeled balancing scooter has shown that the scooter can be ride and able to be controlled to move in forward direction, in backward direction and making left or right turning. Due to the motor maximum speed and the wheel’s diameter, the scooter maximum velocity is 7 MPH with 60 Kgs of passenger weight.
