Dynamic balance principle analysis (the working principle of smart balance car)

It is understood that the working principle of the smart balance car is called the principle of dynamic balance. The principle uses a motion compensation algorithm, using its internal gyroscope and acceleration sensor to accurately detect small changes in the attitude of the car body, and uses a precise servo control system to sensitively drive the motor and adjust accordingly to maintain the entire body. Stable and balanced.

At present, the unicycle intelligent balance car is mainly balanced by the smart chip controller, the attitude sensor and the execution motor. In general, the overall principle of the balancing method of the balance car is similar to that of the drone and the robot.

Balancing the car depends on the principle of dynamic balancing associated with its built-in sensors.

When the user leans on the body, the gyroscope and the acceleration sensor output corresponding posture information. After the controller senses this information, the two motors are commanded to rotate in the corresponding directions. The gyroscope and the accelerometer continuously measure the vehicle attitude at a certain frequency, and output attitude information to the controller. The controller continuously adjusts the rotation direction and the rotation speed of the motor, thus maintaining a dynamic balance.

Reports of safety incidents caused by balancing cars are not uncommon.

The survey found that, like electric bicycles, smart balance vehicles are driven by electric motors, and there is basically no sound during driving, and the speed is very fast, posing a great safety hazard to pedestrians in front, especially the elderly and children. Although many cities have established a number of restrictions on balancing the road, it is still impossible to completely avoid the relevant safety risks.

Controlway Servo Motor Replacement

Controlway Servo Motor Replacement changes the performance-to-cost ratio in many motion control applications. Fast acceleration can be achieved with lower noise and less resonance than conventional servo motors. It can operate at higher bandwidths and achieve outstanding performance, accuracy and results. One-touch tuning, easy operation, shortens tuning time by suppressing residual vibration. Special surface treatment to prevent rust, beautiful and durable. Internally tested for strong corrosion resistance. At the same time, the energy consumption is low, the temperature rise is small, and the tracking error is small.
