Designed of Ball Rolling Control System Based on STM32

This design is a control system that uses a series MCU of STM to control the small ball can run along the specified track to the destination point and stable. It is used STM32F407 and STM32F103 as a control center for the control of signal acquisition and control of the steering wheel. The STM32F407 and the camera OV7670 form the information collection system module. The information that is collected is processed coordinate former by STM32F407, which is sent to another to receive the Bluetooth module by Bluetooth. Then the coordinates are received by STM32F103, which controls the rotation of the two steering gears according to the coordinate information. To control the rigid ball in accordance with the specified trajectory movement and to reach the specified time of stay. When the ball reaches the specified coordinates, use the Positional PID control to stabilize the ball at the specified point.
