Overall Design
The intelligent garbage trolley is designed around an STM32 processor, integrating various modules for autonomous operation. This includes motor drives for movement, a K210 vision module for environmental sensing, a robotic arm for garbage handling, and sensor modules for obstacle detection. The system supports both automatic and manual control modes, with an Android APP for remote supervision and real-time data viewing. The architecture ensures robust performance for line following, garbage recognition, and precise robotic arm manipulation.
Core Innovations
Central to the trolley's intelligence is the K210 Vision Recognition Module, a powerful edge computing device with a deep learning inference engine for image recognition, line following, and garbage classification. The STM32F407 microcontroller acts as the brain, processing complex algorithms. A 5-degree-of-freedom robotic arm is used for precise grabbing and transportation. Ultrasonic sensors enable obstacle avoidance, while Mecanum wheels provide omnidirectional movement, enhancing maneuverability in diverse environments. Bluetooth modules facilitate seamless communication for remote control.
Practical Application
The line following function leverages the K210 module and machine vision algorithms to process recognized lines, calculating centroids to guide movement and avoid obstacles. The robotic arm's actions are precisely controlled by the STM32 based on garbage coordinate detection, utilizing PWM waves for servo motor control. Communication relies on Bluetooth for both command response and automatic connection modes, enabling Android APP control and real-time monitoring. The software system ensures coordinated operation of all modules through task management, providing a highly autonomous and responsive system.

Transforming Urban Waste Management: A Smart City Perspective
Imagine a smart city initiative in a metropolis like Wuhan adopting a fleet of these intelligent garbage trolleys. This deployment would not only fundamentally streamline municipal waste management operations, leading to notably cleaner public spaces and a significant improvement in urban living standards, but also perfectly align with the city’s broader smart city goals. By leveraging AI and IoT technologies, the system provides a robust framework for a more sustainable and technologically advanced future. The autonomous functionality of these trolleys ensures consistent, reliable service, even extending to areas that are typically challenging for manual collection. This ultimately leads to a reduction in human exposure to waste-related hazards and a substantial optimization of resource allocation across vital municipal services.
