TK1入门教程软件篇-安装Turtlebot

说明：

介绍在TK1上如何安装Turtlebot

准备：

安装uvcvideo驱动

参考：安装uvcvideo驱动

安装USB驱动

参考：安装USB驱动

安装Turtlebot：

新建ROS和脚本

mkdir ~/ROS
cd ~/ROS
touch installTurtlebot.sh

查看脚本

vim installTurtlebot.sh

内容如下：

sudo apt-get install ros-indigo-turtlebot ros-indigo-turtlebot-apps ros-indigo-turtlebot-interactions  ros-indigo-kobuki-ftdi ros-indigo-rocon-remocon ros-indigo-rocon-qt-library ros-indigo-ar-track-alvar-msgs

官网的的软件包ros-indigo-turtlebot-simulator不能安装，之后采用源码安装
分配权限，执行安装:

chmod +x installTurtlebot.sh
./installTurtlebot.sh

源码安装turtlebot-simulator
创建工作空间下载源码并编译

mkdir -p ~/turtlebot_ws/src/
cd ~/turtlebot_ws/src/
git clone https://github.com/turtlebot/turtlebot_simulator.git
cd ..
catkin_make

增加工作空间,增加如下代码到~/.bashrc文件

source /home/ubuntu/turtlebot_ws/devel/setup.bash

至此Turtlebot安装完成。

全源码安装

具体方法，参考源码安装Turtlebot：

测试：

连接好Turtlebot2底盘，打开电源
检查是否创建别名：

ls /dev/kobuki

如没，参考增加别名
新终端，启动minimal.launch

roslaunch turtlebot_bringup minimal.launch

新终端，检查底座

rqt -s kobuki_dashboard

新终端，启动键盘控制

roslaunch turtlebot_teleop keyboard_teleop.launch

Hack OpenCV：

安装好的OpenCV版本是2.4.13，但是编译一些包提示需要2.4.8，需要做一些更改，以便使用新版本的
需要变更如下文件：

/opt/ros/<ros-version>/lib/pkgconfig/cv_bridge.pc
/opt/ros/<ros-version>/lib/pkgconfig/image_geometry.pc
/opt/ros/<ros-version>/share/cv_bridge/cmake/cv_bridgeConfig.cmake
/opt/ros/<ros-version>/share/image_geometry/cmake/image_geometryConfig.cmake

新备份目录hacksopencv，备份文件：

$ mkdir ~/hacksopencv
$ sudo cp /opt/ros/indigo/lib/pkgconfig/cv_bridge.pc ~/hacksopencv/cv_bridge.pc-bak
$ sudo cp /opt/ros/indigo/lib/pkgconfig/image_geometry.pc ~/hacksopencv/image_geometry.pc-bak
$ sudo cp /opt/ros/indigo/share/cv_bridge/cmake/cv_bridgeConfig.cmake ~/hacksopencv/cv_bridgeConfig.cmake-bak
$ sudo cp /opt/ros/indigo/share/image_geometry/cmake/image_geometryConfig.cmake ~/hacksopencv/image_geometryConfig.cmake-bak

对以上文件修改如下几处：
1. 删除/usr/lib/arm-linux-gnueabihf/libopencv_ocl.so.2.4.8
2. 替换/usr/lib/arm-linux-gnueabihf/为/usr/lib
3. 替换2.4.8为2.4.13(或当前在opencv4tegra中的OpenCV版本)
使用sed批量替换：

sed -i 's/原字符串/替换字符串/g' filename

删除/usr/lib/arm-linux-gnueabihf/libopencv_ocl.so.2.4.8：

sed -i 's/\/usr\/lib\/arm-linux-gnueabihf\/libopencv_ocl.so.2.4.8//g' cv_bridge.pc image_geometry.pc cv_bridgeConfig.cmake  image_geometryConfig.cmake

替换/usr/lib/arm-linux-gnueabihf/为/usr/lib:

sed -i 's/\/usr\/lib\/arm-linux-gnueabihf/\/usr\/lib/g' cv_bridge.pc image_geometry.pc cv_bridgeConfig.cmake  image_geometryConfig.cmake

替换2.4.8为2.4.13:

sed -i 's/2.4.8/2.4.13/g' cv_bridge.pc image_geometry.pc cv_bridgeConfig.cmake  image_geometryConfig.cmake

最后写成shell，在gist可以获取：
内容为：

#!/bin/bash

#New category
mkdir ~/hacksopencv    

#backup files
sudo cp /opt/ros/indigo/lib/pkgconfig/cv_bridge.pc ~/hacksopencv/cv_bridge.pc-bak
sudo cp /opt/ros/indigo/lib/pkgconfig/cv_bridge.pc ~/hacksopencv/cv_bridge.pc

sudo cp /opt/ros/indigo/lib/pkgconfig/image_geometry.pc ~/hacksopencv/image_geometry.pc-bak
sudo cp /opt/ros/indigo/lib/pkgconfig/image_geometry.pc ~/hacksopencv/image_geometry.pc

sudo cp /opt/ros/indigo/share/cv_bridge/cmake/cv_bridgeConfig.cmake

sudo cp /opt/ros/indigo/share/cv_bridge/cmake/cv_bridgeConfig.cmake

sudo cp /opt/ros/indigo/share/image_geometry/cmake/image_geometryConfig.cmake  ~/hacksopencv/image_geometryConfig.cmake-bak

sudo cp /opt/ros/indigo/share/image_geometry/cmake/image_geometryConfig.cmake  ~/hacksopencv/image_geometryConfig.cmake

#handle
cd ~/hacksopencv

#remove each instance “/usr/lib/arm-linux-gnueabihf/libopencv_ocl.so.2.4.8;“
sed -i 's/\/usr\/lib\/arm-linux-gnueabihf\/libopencv_ocl.so.2.4.8//g' cv_bridge.pc image_geometry.pc cv_bridgeConfig.cmake  image_geometryConfig.cmake 


#replace each instance of “/usr/lib/arm-linux-gnueabihf/” with “/usr/lib“
sed -i 's/\/usr\/lib\/arm-linux-gnueabihf/\/usr\/lib/g' cv_bridge.pc image_geometry.pc cv_bridgeConfig.cmake  image_geometryConfig.cmake 

#replace each instance of “2.4.8” with “2.4.12” (or the current version of OpenCV in opencv4tegra package)
sed -i 's/2.4.8/2.4.13/g' cv_bridge.pc image_geometry.pc cv_bridgeConfig.cmake  image_geometryConfig.cmake 

#cp back 
#sudo cp ~/hacksopencv/cv_bridge.pc /opt/ros/indigo/lib/pkgconfig/cv_bridge.pc 
#sudo cp ~/hacksopencv/image_geometry.pc /opt/ros/indigo/lib/pkgconfig/image_geometry.pc 
#sudo cp ~/hacksopencv/cv_bridgeConfig.cmake /opt/ros/indigo/share/cv_bridge/cmake/cv_bridgeConfig.cmake 
#sudo cp ~/hacksopencv/image_geometryConfig.cmake /opt/ros/indigo/share/image_geometry/cmake/image_geometryConfig.cmake

执行shell

chmod +x hacksopencv.sh 
sudo ./hacksopencv.sh

为了安全起见，注释掉cp back部分代码，自行替换文件。

问题：

问题1：接上usb转串口线，然后ls /dev/则没有ttyUSB0.原因是没有驱动
解决：参考准备的安装USB驱动。因为这是嵌入式设备，需要自己添加驱动到内核。可以直接使用Grinch
问题2：

[rospack] Warning: error while crawling /home/xxx: boost::filesystem::status: Permission denied: "/home/xxx/.gvfs"

解决：

~$ sudo umount /home/congleetea/.gvfs
~$ rm -rf .gvfs/
