MicroROS Self-balancing Car Robot Support 4KG Load Vision Kit The MicroROS Self-balancing Car Robot Support 4KG Load Vision Kit is an advanced Self-balancing Car designed for learning, research, and real-world robotics applications. Built on a powerful STM32 + ESP32 dual-processor architecture, it features a sturdy metal chassis, high-power DC motors, and a 6-axis IMU sensor to deliver stable and precise balancing performance. With support for up to 4 kg load, this Self-balancing two wheel Car can easily handle slopes, obstacles, and dynamic movements while maintaining excellent control and responsiveness. Integrated with MicroROS and ROS2, the robot supports advanced functions such as SLAM mapping, navigation, and AI vision interaction. The Vision Kit includes TOF laser lidar and a ROS-WiFi camera module, enabling real-time obstacle avoidance, autonomous navigation, and visual recognition. An onboard OLED displays live data, while free mobile apps allow remote control and mapping. Ideal for students, educators, and robotics enthusiasts, this Self-balancing Car bridges hands-on hardware learning with powerful ROS-based software development in a single, expandable platform Basic Function The 6-axis IMU enables posture recognition, automatically starting the balance system when placed on the ground and safely shutting it down when lifted vertically. The self-balancing car supports up to 4 kg load, thanks to its sturdy multi-layer structure and high-torque encoder motor, allowing DIY expansion and accessories. With a powerful balance control system, the robot can smoothly climb slopes of up to 30° while maintaining stability. Ultrasonic sensors enable intelligent obstacle avoidance and target following, with easy switching between both modes during operation. The onboard OLED display shows real-time data such as operating mode and battery voltage for quick status monitoring. Equipped with ESP32 + STM32 Dual Processors The ESP32 communication board uses the ESP32-S3-WROOM-1U-N4R2 chip to support MicroROS wireless communication. It enables real-time transmission of data from multiple sensors—such as motors, gyroscopes, and LiDAR—to the virtual machine ROS master, ensuring fast and stable communication between the robot chassis and the ROS system. The STM32 control board , powered by the STM32F103RCT6 chip, is responsible for precise motor driving, gyroscope data processing, and motor encoder feedback. This ensures stable self-balancing performance and accurate motion control. The board also provides onboard expansion interfaces, supporting a wide range of peripheral connections for future upgrades.
