myAHRS+在ubuntu+indigo上安裝過程中遇到的一個錯誤

錯誤：[ERROR] [1498098118.771725090]: Initialize() returns false, please check your devices.

解決：1）ls /dev/tty*  查看所有tty串口，看是否有/dev/ttyACM0；

            2）sudo chmod 666 /dev/ttyACM0  給/dev/ttyACM0權限；

 
myAHRS+安裝如下：

1）安裝

Install the package:

sudo apt-get install ros-indigo-myahrs-driver

Install the package from the github:

cd ~/catkin_ws/src
git clone https://github.com/robotpilot/myahrs_driver.git
