遥控

遥控前为了让turtlebot接受命令，需要启动

roslaunch turtlebot_bringup minimal.lauch

键盘操作命令：

roslaunch turtlebot_teleop keyboard_teleop.launch

简单脚本控制：

首先输入命令

roslaunch turtlebot_bringup minimal.launch

然后运行编写的脚本，如直行脚本：goforward.py

python goforward.py

其内容如下：

#!/usr/bin/env python

# A very basic TurtleBot script that moves TurtleBot forward indefinitely. Press CTRL + C to stop.  To run:

若想要tb2(turtlebot2,下同)走正方形等可自行探索其他脚本：

https://github.com/markwsilliman/turtlebot/

注：turtlebot只使用线性的。X和Z值的角，因为它在一个平面作品（2D）的世界，但无人机，海洋机器人与其他机器人占据的三维环境中，线性的。Y，X和Y的角，角的值是可用的。

turtlebot开始在地板上画正方形但你会发现它很快开始漂离出发的路径。这是机器人和计算机的作用非常不同的地方。如果你问一台电脑做2 + 1，你会总是收到1。如果你问一个机器人向前移动1米，它将去大约一米，而不是完全直。知道机器人是（定位）是一个经典的机器人的挑战之一，尤其是在室内环境中，全球定位系统是不可靠的或足够精确。

你可能会认为，因为你可以告诉机器人在0.2米/秒，这将是很容易编程的机器人，使它前进一米，通过发布一个线性的。x = 0.2米/秒5秒。如果机器人是一台计算机，这是完全正确的，但对于机器人，这是非常不准确的，由于打滑，不完善的校准，和其他因素。如果你写一个这样的脚本驱动在一个正方形，并运行10个周期，你会结束一个完全不同的地方，从你开始！幸运的是，令人惊讶的科学家和研究人员正走在我们的前面

创建地图：

roslaunch turtlebot_bringup minimal.launch
roslaunch turtlebot_navigation gmapping_demo.launch

roslaunch turtlebot_rviz_launchers view_navigation.launch
roslaunch turtlebot_teleop keyboard_teleop.launch

保存地图：

rosrun map_server map_saver -f /tmp/my_map
ls /tmp/

现在你可以看到两个文件在/tmp目录my_map.pgm和my_map.yaml。

自主驾驶：

roslaunch turtlebot_bringup minimal.launch
roslaunch turtlebot_navigation amcl_demo.launch map_file:=/tmp/my_map.yaml

如果你看到 odom received! 说明已经正常运行。

问题

如果你收到一个警告：Waiting on transform...，先重启minimal.launch，重新启动amcl_demo.lauch。您可能需要尝试重新启动几次。同时，关闭Kobuki基站并重开。

turtlebot成功运行，在工作站运行：

roslaunch turtlebot_rviz_launchers view_navigation.launch --screen

rviz应该公开展示你的地图。turtlebot不能够估计在启动姿态，尽管它可以在你初始化它的姿态。

选择“2D Pose Estimate”在地图上的turtlebot位置点击并按住。当你握着鼠标的时候，一个箭头会出现在鼠标指针的下方，用这个来估计它的方向。
设置后估计的姿态，选择“2D Nav Goal”，点击你想让turtlebot去的地方。您还可以指定一个目标方向，使用相同的技术如“2D Pose Estimate”。
turtlebot现在应该朝着你的目录自主前进。尝试指定一个目标，并走在前面，看看它如何反应的动态障碍。

编码实现前进与避障

roslaunch turtlebot_bringup minimal.launch
python ~/helloworld/goforward.py

tb2会前进，撞到东西，ctrl+c停止；

若要实现避障

roslaunch turtlebot_bringup minimal.launch
roslaunch turtlebot_navigation amcl_demo.launch map_file:=/tmp/my_map.yaml
roslaunch turtlebot_rviz_launchers view_navigation.launch --screen
python ~/helloworld/goforward_and_avoid_obstacle.py

tb2不能可靠地确定其初始姿态（在哪里）所以我们就把它用“2D Pose Estimate”。选择“2D Pose Estimate”和指定的位置turtlebot。保持rviz打开，我们可以监视它的路径规划。

提示：在你估计tb2的姿势可以可靠地知道它在哪里，甚至在旅行。

当它在驾驶时, 尝试走到机器人的路径，看看它如何响应。

为什么它会在转圈？

turtlebot四处寻找特征，比较他们的地图，以确定它的位置。这个过程被称为本地化。

从代码分析：

请注意，而不是说“向前几秒钟”，我们说：“无论什么路径，我们想在前进3米位置的地方结束”。turtlebot可能需要60秒来试图找到一个路径到这个位置。

定点自导航：

roslaunch turtlebot_bringup minimal.launch
roslaunch turtlebot_navigation amcl_demo.launch map_file:=/tmp/my_map.yaml
roslaunch turtlebot_rviz_launchers view_navigation.launch --screen

在RViz，选择“二维姿态估计”，点击地图约在turtlebot是对准箭头指示方向。

下一步，选择“发布点”，将鼠标悬停在你的地图（但不要点击），你想turtlebot去当你运行你的脚本。在屏幕的左下角旁边“选择这一点”，你会注意到三个数字，当你移动鼠标。这是你的观点，所以写下这些数字吧。

提示：第三个数字是高度。它可能会显示一个数字，不是完美的0，但不管它说什么，使用0。

在一个新的终端窗口运行：

gedit ~/helloworld/go_to_specific_point_on_map.py

83行

position = {'x': 1.22, 'y' : 2.56}

重写X，Y值与你写下的数字时，做“发布点”。保存和退出。

然后运行：

python ~/helloworld/go_to_specific_point_on_map.py

注：如先前看到的，turtlebot会避开障碍物，要计算一个合理的路径，只要rospy.duration期限没有过期。

提示：如果你认为你amcl_demo.launch终端运行它将显示一个报告，告诉你的时候，TurtleBot已经放弃了试图达成一个目标。

查看电池状态：

先启动

roslaunch turtlebot_bringup minimal.launch

查看发布的主题

rostopic list

其中

/laptop_charge 是笔记本电量信息
/mobile_base/sensors/core 是Kobuki底座的电量信息

可直接监听

rostopic echo /laptop_charge

或者运行脚本

cd ~/helloworld/
python netbook_battery.py

笔记本电池脚本：

rospy.Subscriber("/laptop_charge/",SmartBatteryStatus,self.NetbookPowerEventCallback)

这意味着，“每一次新的数据公布在线程/laptop_charge/ 。self.NetbookPowerEventCallback”

SmartBetteryStatus 是数据类型的线程包含。此数据类型定义在包含命令（在脚本的顶部附近）：

from smart_battery_msgs.msg import SmartBatteryStatus

现在让我们看看在功能NetbookPowerEventCallback。数据传递给功能，组件可以打印这样：

 print("Percent: " + str(data.percentage))

重要提示：稍后我们会检查是否data.percentage大于50看我们是否需要充电。Python是很严格的时候，比较不同类型的数据，所以总是用int()转换。例子:

if (data.percentage < 50):

会导致一个错误，但：

if(int(data.percentage) < 50):

将工作正常。

底座电池信息：

有多个电池，用于kobuki基地。功率百分比是用在kobuki_battery.py固定kobuki_base_max_charge值计算。

确定你的电池的最大充电到满，让它在停靠站的一段，然后在turtlebot运行：

rostopic echo /mobile_base/sensors/core

注意电池的值，和编辑kobuki_battery.py：

gedit kobuki_battery.py

修改kobuki_base_max_charge价值。百分比功率现在将正确计算。

按键事件：

roslaunch turtlebot_bringup minimal.launch
python kobuki_buttons.py

会提示

跟随实验

roslaunch turtlebot_bringup minimal.launch
roslaunch turtlebot_follower follower.launch

参数修改：

# pre-groovy
rosrun dynamic_reconfigure reconfigure_gui
# groovy or later
rosrun rqt_reconfigure rqt_reconfigure

选择 camera/follower
移动滑块则Turtlebot的跟随行为就改变
Android 客户端

参考Android 配对通过Android客户端，可以运行跟随演示，开始或停止跟随行为。

全景图实验：

turtlebot3的功能

roslaunch turtlebot_bringup minimal.launch
roslaunch turtlebot_panorama panorama.launch

创建全景图，有两种方法创建。

rostopic pub turtlebot_panorama/take_pano std_msgs/Empty
rosservice call turtlebot_panorama/take_pano 0 360.0 30.0 0.3

2、停止

rostopic pub turtlebot_panorama/stop_pano std_msgs/Empty
rosservice call turtlebot_panorama/take_pano 2 360.0 30.0 0.3

配置参数

上面利用rosservice 调用就使用了参数。2(模式) 360.0(角度) 30.0（间隔） 0.3（旋转速度）

模式：

0 for snap&rotate (i.e. rotate, stop, snapshot, rotate, stop, snapshot, ...)
1 for continuous (i.e. keep rotating while taking snapshots)
2 to stop an ongoing panorama creation

角度
创建快照和旋转模式时为角度间隔（度），其他模式为时间间隔（以秒为单位）
旋转速度（弧度/秒）

查看结果

在工作台上，执行命令：

rosrun image_view image_view image:=/turtlebot_panorama/panorama

注意：先执行此命令，在执行创建全景图命令，360度自转完成，即自动生成全景图, 点击图片右键即可自动保存。

cartographer

cartographer是少有的基于优化的开源激光SLAM。因为同通常的scan-to-scan激光匹配会累计误差，所以它引入了Submap这一概念，将原来的scan-to-scan匹配变成了scan-to-map匹配，就是激光先和submap进行匹配。

每次得到一帧激光scan数据之后，cartographer将其与最近的submap去进行匹配，找到一个最优的位姿，将scan插入到submap中，因为在一个较短的时间内，这个匹配过程不会累加什么误差。当submap完成之后，便不会再有任何激光数据插入其中，它就是一个独立的已经完成了子地图，它只参与闭环的匹配了。接下来的工作有点类似与拼图过程，我们通过调整每个submap的位姿，使所有的submap之间互相重叠的部分(即约束)误差最小。

需要安装3个软件包，ceres solver、cartographer和cartographer_ros。为了管理方便，建立carto目录来存放ceres solver、cartographer。
安装依赖

sudo apt-get install -y google-mock libboost-all-dev  libeigen3-dev libgflags-dev libgoogle-glog-dev liblua5.2-dev libprotobuf-dev  libsuitesparse-dev libwebp-dev ninja-build protobuf-compiler python-sphinx  ros-indigo-tf2-eigen libatlas-base-dev libsuitesparse-dev liblapack-dev

首先安装ceres solver，选择的版本是1.11

cd ~/carto
git clone https://github.com/hitcm/ceres-solver-1.11.0.git
cd ceres-solver-1.11.0/build #如果build目录不存在，就自己建mkdir build
cmake ..
make –j
sudo make install

然后安装 cartographer

cd ~/carto
git clone https://github.com/hitcm/cartographer.git
cd cartographer/build   #如果build目录不存在，就自己建mkdir build
cmake .. -G Ninja    #3
ninja
ninja test
sudo ninja install

上述第3步执行错误的同学可以忽略3-6步，改用下面的方法。

cmake  ..
make
sudo make install

安装cartographer_ros

谷歌官方提供的安装方法比较繁琐，我对原来的文件进行了少许的修改，核心代码不变，只是修改了编译文件

下载到catkin_ws下面的src文件夹下面

git clone https://github.com/hitcm/cartographer_ros.git

然后到catkin_ws下面运行

$ catkin_make

新包加入环境

$ source ~/.bashrc
$ rospack profile

数据下载测试, 并上传到carto目录下。

2d数据，大概500M，用迅雷下载

https://storage.googleapis.com/cartographer-public-data/bags/backpack_2d/cartographer_paper_deutsches_museum.bag

3d数据，8G左右，同样用迅雷下载

https://storage.googleapis.com/cartographer-public-data/bags/backpack_3d/cartographer_3d_deutsches_museum.bag

然后运行launch文件即可。

roslaunch cartographer_ros demo_backpack_2d.launch bag_filename:={$HOME}/carto/cartographer_paper_deutsches_museum.bag

roslaunch cartographer_ros demo_backpack_3d.launch bag_filename:={$HOME}/carto/cartographer_3d_deutsches_museum.bag

刚开始使用ROS的同学运行下面两句是无法工作的，可能出现的错误如下。

[demo_backpack_2d.launch] is neither a launch file in package [cartographer_ros] nor is [cartographer_ros] a launch file name
The traceback for the exception was written to the log file

这种错误的主要原因是ros的catkin_ws配置问题，可以运行rospack profile试试。
实在不行还有如下所示的两种解决方法。推荐第二种。

最终结果如下图

2d效果

3d效果

gmapping建图和amcl导航

建图：

我们这里需要一个将深度图转为激光数据的包

$ cd ~/catkin_ws/src
$ git clone  https://github.com/ros-perception/depthimage_to_laserscan.git

我这里新建了一个bringup的包来专门存放launch 文件

$ cd ~/catkin_ws/src
$ catkin_create_pkg bringup  roscpp

在 bringup包内我们新建一个launch文件夹，然后在launch文件夹里添加
kinect2_depthimage_to_laserscan_rviz_view.launch文件

$ cd ~/catkin_ws/src/bringup
$ mkdir  launch 
$ touch  launch/kinect2_depthimage_to_laserscan_rviz_view.launch

基本工作我们都做完了，现在我们需要编译一下

$ cd ~/catkin_ws
$ catkin_make 
$ rospack profile

我们现在可以接上KinectV2（注意！！！接USB3.0口）.

测试：

新终端，执行

roslaunch bringup kinect2_depthimage_to_laserscan_rviz_view.launch

效果：

查看TF树：文件生成在主文件夹

cd ~
rosrun tf view_frames

效果：

安装依赖包

安装Gmapping包

$ cd ~/catkin_ws/src
$ git clone  https://github.com/ros-perception/slam_gmapping.git
$ cd ~/catkin_ws
$ catkin_make 
$ rospack profile

在我们之前的建的bringup/launch/下新建kinect2_gmapping.launch文件

$ cd ~/catkin_ws/bringup/launch/
$ touch kinect2_gmapping.launch
$ vim kinect2_gmapping.launch

代码如下：

</launch>

在我们之前的建的bringup/launch/下新建kinect2_gmapping_rviz_view.launch文件
我们这里不把启动RVIZ写在kinect2_gmapping.launch里是方便以后的远程启动

$ cd ~/catkin_ws/bringup/launch/
$ touch kinect2_gmapping_rviz_view.launch
$ vim kinect2_gmapping_rviz_view.launch

内容如下：

<?xml version="1.0"?>

<launch>

    <!--start rviz view -->
    <node name="rviz" pkg="rviz" type="rviz" args="-d $(find bringup)/rviz/kinect2_gmapping.rviz" />

</launch>

还有在新建bringup/rviz/下新建kinect2_gmapping.rviz文件

$ cd ~/catkin_ws/bringup/rviz/
$ touch kinect2_gmapping.rviz
$ vim kinect2_gmapping.rviz

最后我们依次启动我们的launch文件便可

$ roslaunch kinect2_gmapping.launch
$ roslaunch kinect2_gmapping_rviz_view.launch
$ rosrun teleop_twist_keyboard teleop_twist_keyboard.py

这样子我们就可以愉快的控制小车移动来建图了，当你建好图后运行一下指令就可以保存地图：

rosrun map_server map_saver -f mymap

地图保存在主文件夹，两个文件，mymap.pgm 和 mymap.yaml
效果：

TF树：

$ cd ~
$ rosrun tf view_frames

效果：

AMCL导航：

安装一下所需的包

$ cd ~/catkin_ws/src
$ git clone -b indigo-devel https://github.com/ros-planning/navigation 
$ cd ~/catkin_ws
$ catkin_make 
$ rospack profile

在我们之前的建的bringup/下，新建nav_config文件夹,然后新建四个文件

$ cd ~/catkin_ws/bringup/
$ mkdir nav_config
$ touch base_local_planner_params.yaml
$ touch costmap_common_params.yaml
$ touch global_costmap_params.yaml
$ touch local_costmap_params.yaml

这四个文件主要用于导航配置

（1）base_local_planner_params.yaml文件内容：

update_frequency: 1.0
publish_frequency: 0
static_map: true
rolling_window: false
resolution: 0.01
transform_tolerance: 0.5
map_type: costmap

（4）local_costmap_params.yaml文件

local_costmap:
global_frame: /odom
robot_base_frame: /base_link
update_frequency: 1.0
publish_frequency: 1.0
static_map: false
rolling_window: true
width: 6.0
height: 6.0
resolution: 0.01
transform_tolerance: 0.5
map_type: costmap

在我们之前的建的bringup/下，新建map文件夹
然后将之前建图生成的两个文件 mymap.pgm 和 mymap.yaml 移到map文件夹里
然后修改 mymap.yaml ，做如下修改：将image这一行的改为你的mymap.pgm文件所在路径，如

image: /home/forrest/catkin_ws/src/bringup/map/mymap.pgm

在我们之前的建的bringup/launch/下新建kinect2_nav.launch文件

$ cd ~/catkin_ws/src/bringup/launch/
$ touch kinect2_nav.launch
$ vim kinect2_nav.launch

代码如下：
