ZYC0222 STM32 ROS Robot Car

Hardware Components: STM32 ROS robot main control board (STM32F407VET6), ESP32CAM motherboard, ultrasonic module, three-way line tracking module, matrix screen module

Board Introduction: The ROS robot control board uses the high-performance STM32F407VET6 main control chip and integrates important key configurations such as the IMU attitude sensor. In addition, the control board provides four encoder motor interfaces, PWM/bus servo interfaces, an LCD color screen display, and communication peripheral interfaces such as USB/SBUS/CAN/Bluetooth. Only one USB cable is needed to control and read encoder motors, various servos, and various peripherals—simple and efficient!
We provide ROS1 and ROS2 SDK packages based on Python 3, allowing you to flexibly switch between Raspberry Pi JetsonNano and other robot controllers. We also provide complete RoS Robot Controller project code, including modules for motor control, attitude calculation, and host computer communication, and include built-in USB HOST, SBUS, I2C, UART, and multiple GPIO expansion interfaces, making it an excellent choice for various robot development!

Function Introduction:

• 1. Adjusts direction based on drawn or taped lines using signals from three infrared tracking modules to achieve tracking functionality. (Due to wheel friction limitations, small-angle turns are not possible.)
• 2. Determines distance using ultrasonic waves. Moves forward (far distance) or backward (near distance) when the distance is too far or too close. (Follow mode cannot turn.)
• 3. Automatic forward movement. Determines if there are objects ahead using ultrasonic distance measurement. Turns right when the distance is too short. If the distance is still too close after turning, continues turning right until the distance is sufficient, then continues forward.
• 4. The device will display corresponding expressions based on user actions, and will also display appropriate expressions based on actions when the desired mode is activated.
• 5. The ESP32 CAM connects to your phone's hotspot and provides a website address. After opening the website via an app or browser, you can control the car using the buttons on the interface.
