极限4天排队调车，时间太赶了，代码写得很差，一旦识别不了后面的就走不了，后面想重写也没时间。由于官方用的模板匹配识别的太慢，打算用yolov5 -lite模型识别，openvino部署，后面也来不及用上。现在，把yolov5 -lite 大写数字一到八的检测模型 .onnx文件送上，准确率95%

ssh -Y  abot@192.168.135.6
sudo  nautilus                                
scp -r  abot@192.168.135.6:/home/abot/robot_ws D: 

主目录运行：
 建图：  ./1-gmapping.sh      保存： roslaunch robot_slam save_map.launch
射击： roslaunch abot_bringup shoot.launch   发射驱动程序
rostopic pub /shoot  std_msgs/String "data: '' "   发布射击的空话题，等待发射
识别：
roslaunch usb_cam usb_cam_test.launch   打开相机
rosrun rqt_image_view  rqt_image_view   可视化相机
语音：
连接蓝牙耳机WI-C200
roscore
rosrun  robot_voice   tts_subscribe
rostopic  pub /voiceWords std_msgs/String "data: '1234' "

启动导航与识别：
3-mission.sh 在这里
roslaunch track_tag usb_cam_with_calibration.launch  打开相机节点
 roslaunch track_tag ar_track_camera.launch   启动二维码识别节点
 rosrun robot_voice tts_subscribe; exec bash  语音播报节点
robot_slam/launch/multi_goal.launch  修改导航的目标点的坐标值
robot_slam/scripts/ navigation_multi_goals.py  修改对应id分别走到哪个点

--------------------------------------------------------------------------------------

把官方给的代码放到 src\robot_slam\scripts  里面

--------------------1. 自主巡航------------------------------

修改导航的目标点的位姿：   robot_slam/launch/multi_goal.launch  
X Y Yaw 一列为一组值 ，一一对应（分别表示goal[0] ...goal[1]）， Yaw是角度制，90.0表示逆时针旋转90度（正值向左）

识别：（视频的第35分钟）
roslaunch usb_cam usb_cam_test.launch   打开相机
roslaunch  find_object_2d  find_object_2d6.launch  启动识别程序

Edit -- Add object -- Take picture截图 --框选物体 --End --File --Save object 路径选择 abot_find/object/   
然后对图片进行特殊命名（数字范围）
-------没有ar_cb函数py

--------------------2. 目标射击------------------------------

user_demo/param/mission.yaml    修改射击目标点的相关参数

roslaunch usb_cam usb_cam_test.launch   打开相机
roslaunch  find_object_2d  find_object_2d6.launch  启动识别程序
rosrun  robot_slam   III.py   识别结果判断
rostopic echo /object_position

跟踪标签：在6-mission.sh里有 ，
roslaunch  track_tag usb_cam_with_calibration.launch
roslaunch  track_tag ar_track_camera.launch

rostopic echo /ar_pose_marker

然后运行官方给的代码  rosrun robot_slam  .py   ，需要把代码整合起来，能够识别三种目标并射击
 

启动代码前一定要插上炮台的USB串口线，不然运行就会报错没有串口 /dev/shoot

记得打开炮台开关

---------------------------------------------------------------------------
查看坐标点
运行navigation.sh脚本前注释掉最后一行 ，在打开的地图里点击目标点前 运 rostopic echo /move_base_simple/goal
在导航地图中使用RViz中的navigation goal标定目标后，到终端的输出查看pose 字段，里面有x,y目标点
直接拿迟来量坐标比较快，单位是米，搞懂ros坐标系

编译及运行--------------------------------------------------------------------
catkin_make    
catkin_make -DCATKIN_WHITELIST_PACKAGES="robot_slam"

source devel/setup.bash
source /opt/ros/melodic/setup.bash
 

参加比赛要注重交流，从比赛中获得友情，知识和实践，面对困难永不放弃的决心，不要把奖项看的那么重要。

在小车的主机里插入鼠标，连接WIFI，使用屏幕键盘输入密码，剩下的交给远程控制。

同一局域网下ssh传输文件：

无论是windows还是ubuntu，都可以互传文件

同一局域网多人连接：

一个主要的人负责用向日葵远程控制小车，进行调试

一个次要的人负责使用ssh连接，在里面写代码，查看文档

等调完半小时，换另一个远程控制调车。

（Vscode的ssh远程连接修改代码）（或者，在虚拟机里ssh连接小车主机<加Y参数 ssh -Y IP>，在终端里执行 sudo  nautilus  打开并编辑文件管理器）

功能包重名，就修改launch文件名区别开，如过.sh脚本运行报错，单独分开命令运行试试，记得source自己的工作空间

复制别人的工作空间，需要重新编译，不然setup.bash还是用的原来的，串到原来的代码

编译：

catkin_make    # 若失败，删除build目录和devel目录试试

catkin_make -DCATKIN_WHITELIST_PACKAGES="robot_slam"

catkin build 包名

 Ctrl+h 修改环境变量.bashrc
