編譯rbx1時遇到錯誤

環境 Ubuntu 16.04 ，ROS kinetic
問題1：

解決：
賦予cfg資料夾可執行許可權。首先找到你的cfd資料夾的路徑（比如我的路徑是/home/acl/rbx1/src/rbx1_nav/cfg），然後執行以下指令：

chmod -R +x /home/acl/rbx1/src/rbx1_nav/cfg

問題2：
編譯通過後，按照以下指令啟動可執行檔案時報錯：

rosrun rbx1_nav calibrate_linear.py

報錯；

[rosrun] Couldn't find executable named calibrate_linear.py below /home/acl/rbx1/src/rbx1_nav
[rosrun] Found the following, but they're either not files,
[rosrun] or not executable:
[rosrun]   /home/acl/rbx1/src/rbx1_nav/nodes/calibrate_linear.py

原因：
calibrate_linear.py檔案沒有可執行許可權。
解決：
按照報錯的路徑找到calibrate_linear.py，右鍵屬性->許可權，勾選上「允許作為程式可執行檔案（E）」，如下圖紅框中所示：

再次執行以下指令即可成功執行該檔案啟動機器人。

rosrun rbx1_nav calibrate_linear.py
