设计了一款能实现垃圾分类、自动开盖、自动避障、自动行驶等功能的智能家居垃圾桶。运用连杆机构构建出机械结构，采用语音识别的方式进行控制，运用STM32单片机编程实现整体电路的运行。使用专业绘图软件完成对各个模块电路原理图的绘制，分析了机械结构及电路模块的设计思路与过程，介绍了对垃圾桶采用语音控制的优点，对具体程序如何实现垃圾桶各个动作电路的功能作出了分析说明，对垃圾桶的机械结构、电机驱动原理、语音识别原理、PWM技术也做了相应介绍。

We designed an intelligent household trash can that can realize the functions of garbage classification,automatic lid opening, automatic obstacle avoidance, automatic driving, etc. The linkage mechanism is used to construct a mechanical structure. The trash can is controlled by voice recognition and the operation of the whole circuit is realized by STM32 microcontroller programming. The circuit schematic diagrams of each module are drawn with a professional drawing software. The design ideas and process of the circuit module and mechanical structure are analyzed. The advantages of using voice control for the trash can and the specific program to realize the functions of each action circuit of the trash can are explained. The mechanical structure of the trash can, the principle of motor drive, the principle of speech recognition and the PWM technology are also introduced accordingly.
