实现机械臂校准
1作步骤
Step 1: Atom烧录最新版的atomMain。
Step 2: 在桌面新建一个 Python 文件为 *.py，将下列代码拷贝进去并保存。
注意：文件命名为：rasp_mycobot_test_gui.py。

Step 3: 打开打开终端（快捷键CTRL+ALT+t），输入以下命令，然后点击回车：
cd Desktop
python3 rasp_mycobot_test_gui.py
Step 4: 选择相应的波特率，然后点击连接。
- myCobot 280-Pi：1000000
- myCobot 320-Pi：115200
Step 5: 手动将各个机械臂各关节归于零位，点击开始校准。界面出现校准结束，机械臂校准完成。
