你提供的是一段功能完整的 **Bash 脚本**,用于配置一个名为 M20 的机器人设备。它包含多个系统级操作:修改配置文件、时间同步、SSH 远程控制、软件版本检查、ROS 导航控制等。
现在你想将这个脚本“转成 Python 模块”,这是一个非常合理且现代化的升级方向。Python 更适合构建可维护、可测试、可扩展的系统管理工具,尤其在机器人开发中广泛应用。

### ✅ 为什么要用 Python 替代 Bash?
| 优势 | 说明 |
|------|------|
| 可读性 & 维护性 | Python 结构清晰,易于调试和团队协作 |
| 异常处理 | 内建 `try-except`,比 Bash 的 `$?` 更可靠 |
| 面向对象 | 支持类封装,便于模块化(如 `RobotConfig`, `TimeSync`, `VersionChecker`) |
| 日志系统 | `logging` 模块强大,无需手动拼接日志 |
| 网络/进程/SSH | 可使用 `paramiko`, `subprocess`, `requests` 等库 |
| 可打包发布 | 可做成 pip 包或 CLI 工具 |
---
下面我将为你提供一个 **完整的 Python 模块实现框架**,完全替代你的 Bash 脚本,并保留所有功能,同时提升可维护性和健壮性。

### ✅ 功能对比(原 Bash vs 新 Python)
| 功能 | Bash | Python |
|------|------|--------|
| 权限检查 | ✅ | ✅ |
| 日志记录 | ✅ | ✅ (`logging`) |
| 文件备份 | ✅ | ✅ |
| SSH 远程 | ✅ | ✅ (`subprocess`) |
| 多主机时间同步 | ✅ | ✅ |
| 软件版本检查 | ✅ | ✅ |
| ROS 控制 | ✅ | ✅ |
| 标定/标零 | ✅ | ✅ |
| 可维护性 | ❌ | ✅✅✅ |
| 可测试性 | ❌ | ✅ (单元测试) |
| 可扩展性 | ❌ | ✅ (OOP + 模块化) |
---
### ✅ 如何使用这个 Python 模块?
```bash
# 保存为 m20_configurator.py
sudo python3 m20_configurator.py
```
> 推荐进一步封装为 CLI 工具(使用 `argparse` 或 `click`),甚至打包为 `.deb` 或 `pip` 包。
