Ros porting notes 1
Recently, some devices have been transplanted, and they are sorted out here one after another.
The first is some basic startup instructions
1. First find the share folder and view the launch file
cd ~/catkin_ws/install/share/(自己的用户名)/launch
2. View rostopic, what I see here is the function of QR code positioning
rostopic echo /tag_detections_image
There is no response here
3. Turn off the rosnode and restart it
rosnode kill -a
Corresponding folder to view files
ls -l
4. Start the boot configuration
cd ~/catkin_ws
./boot.sh
