自主导航机器人是移动机器人技术的核心能力，其本质是融合感知、定位、建图、规划与控制的闭环系统。基于ROS的导航栈（如gmapping+move_base）提供了标准化实现路径，但真实落地需深入理解TF坐标变换、代价地图分层机制、DWA局部规划原理及硬件抽象接口。OpenBot作为轻量级实机验证平台，完整复现 ...
这篇保姆级教程就是给你原样复刻用的。核心链路是ESP32通过蓝牙接收手机音频，再走I2S总线送给数字功放芯片MAX98357A，最后推喇叭出声。整条链路用Arduino IDE就能搞定，不碰复杂的ESP-IDF工程，不需要示波器，甚至不太需要焊接基本功。你只要有一块ESP32开发板、一个MAX98357A模块、一个小喇叭，再加 ...
