Hardware & Simulation set up

這記錄了PC、樹莓派中的環境建置，以及基本的ROS套件模擬。
# 最新版本(ubuntu 22.04+ROS2 Humble)
## rpi4環境安裝
### 燒錄作業系統(ubuntu 22.04_desktop（64-bit）)
(error1:因為網路實在太慢了，還好我本地端電腦裡就有Ubuntu的iso檔，我就直接用了。注意設定當中可以先允許連接無線網路，以及ssh連接。)
(error2:windows不支援大型sd卡的格式化😑最後還是派上老朋友rufus來下手，具體步驟請參考：https://youtu.be/0l7Bx3yTUq4?si=0I7HS2NTCh4wV5BC)

# 112-2學期中版本
## 模擬環境配置 VM ware
### 建立虛擬環境ubuntu 20.04
> 所有模擬皆在VMware 17的ubuntu 20.04（20GB）運行
> 測試者：Sheena
> 運行PC：CPU-AMD Ryzen 9 5900HX

**Basic GOAL:**
1. 安裝ROS2 Foxy
2. 執行Beginner:CLI tools
3. 從CLI工具中，學會以下基本的概念：
- [x] Node節點
- [x] Topic主題
- [x] Services服務
- [x] Parameters參數
- [x] Action行動
4. 下載Git

2-1爲了選擇一個domain ID，挑了特別的數字✨20✨
2-2執行各個基礎教程，具體步驟參見Roger筆記：https://hackmd.io/@Rogger/Sy0wMSGq6

🔼I've try to draw letter "F" to represent our project theme, which related to "fire🔥". However, the distance was hard to control😂turns out to be a weird "f" look.
🔼Created my other turtle, named "FIRE", fortunately it shown as a red turtle🔥Also, I drew an abstract picture by changing their set pen...

### 創建工作包 Building workspace through colcon

$ mkdir -p sim_ws/src  
$ cd sim_ws/           
$ colcon build --symlink-install
$ ros2 pkg create --build-type ament_cmake {$FILE NAME : ex.sim_package}

> **`mkdir -p`**：創建新路徑 Create a new "parent" directory
> **`cd`** ：前往該資料夾 Move to this directory
> **`colcon build`** ：這種build的類型可以有更好的迭代
> Allow files to be changed in source space for better iterationn
> **`ros2 pkg create`**：依模版創建包 Create a new package based on a template
> **`--build-type`**：Colcon使用packge.xml的形式，支援不同的創建種類，依Foxy教程則最推薦使用兩種：`ament_python` ,`ament_cmake`

ERRORs:
1. netplan doesn't allow "TAB"→ change to space
2. format should be strictly followed: there is colon(:) after SSID's name
