Problems in connections with Gazebo Simulator about px4-avoidance

[tuloski]

I have the same problem: PX4/PX4-SITL_gazebo-classic#322
I don't think updating to Gazebo8 is the right solution, also because gazebo7 is installed from the scripts in the instructions.

Moreover it's weird that the "make px4_sitl_default gazebo" works while the roslaunch doesn't. Can it be a "timing" issue?

I have the same problem when "make px4_sitl_default jmavsim", after information message shown,
INFO [simulator] Waiting for simulator to connect on TCP port 4560
and no update.

@SwiftGust The issue is not related to the avoidance, but your SITL environment is misconfigured.

Have you tried following the instruction provided in the px4 documentation?

@Jaeyoung-Lim
Hello, I have install and did try to solve this issue with referencing mavros, px4 dev docs, discuss forums and so on and i have come to conclusion that something wrong regarding communication setup of this repository.

I had to handle some errors that didn't mentioned in as following repo's doc
and I did install mavros master branch from source.

As I described in problem 1, PX4 Gazebo itself does work very well
as well as MAVROS so I can do arm, set mode, take off from mavros.

What I'm describing here is that I'm suspecting the cause of this issue #159
is Gazebo and PX4 SITL cannot communicate, consequently MAVROS doesn't work
when using launch file of this repository.

[nicovanduijn]

Which launch file are you using? Generally, the launch file needs to set up this communication properly, e.g. by passing <arg name="fcu_url" default="udp://:14540@localhost:14557"/> to the mavros node.

The launch files in this repository intended for SITL set this argument as I mentioned, as far as I know. But feel free to submit a PR if you find a broken one.

[SwiftGust]

I tried and checked follow launch files and nothing works.

roslaunch global_planner global_planner_sitl_mavros.launch
roslaunch local_planner local_planner_stereo.launch
roslaunch local_planner local_planner_depth-camera.launch
roslaunch local_planner local_planner_sitl_3cam.launch

Those parts are of no problem regarding this matter.
Nested launch files are nothing much differ from launching PX4 SITL Gazebo with separate MAVROS launch which works fine in my desktop.

What I don't know and suspected cause of problem is something keeps
PX4 SITL instance waiting for Gazebo to be connected in TCP port 4560 and no update since while port was not in use and everything is up and running (Gazebo, RViz, rqt reconfigure...)

[nicovanduijn]

The above messages do not indicate any problem, they are all fine. Can you paste the complete output when running roslaunch local_planner local_planner_sitl_3cam.launch ? It works on my machine, as well as all my co-workers with the current master.

[SwiftGust]

@nicovanduijn Hello, what I'm guessing is that whatever the message is missing connection established between PX4 SITL - GAZEBO.

Can you check if the most recent Firmware change fixes your problem? (#174)

[altshuler]

Hello.

I have the same problem.
I'm running the latest master of PX4 Firmware and Avoidance projects.

[mrivi]

try to increase the number of watches e.g. sudo sysctl fs.inotify.max_watches=65536

[SwiftGust]

@nicovanduijn
I have reinstalled and built both of PX4/avoidance & PX4/Firmware today, problem still presents.
I checked messages of earlier and now getting the same except stamp and process id as well as rqt-graphs, so I won't append it.
Thank you for your effort.

@mrivi Annoying messages are gone now. Thank you.

[mrivi]

can you share your ROS_PACKAGE_PATH, GAZEBO_MODEL_PATH, GAZEBO_PLUGIN_PATH and LD_LIBRARY_PATH? thank you.

[SwiftGust]

@mrivi Sure, I manually separated it with a colon
Clearly it looks like something to do with environment variable setup.

For the clarity, I do have ardupilot-gazebo repository setup in my desktop
and I did suspected that few days ago
so I have temporarily removed it from the PATH variables but didn't worked.
Also, there could've been a URI conflict but never happened,
it looks like handles well about what it is looking for.

[mrivi]

@SwiftGust I think you're missing the Firmware build path in LD_LIBRARY_PATH. Run
source ~/catkin_ws/src/Firmware/Tools/setup_gazebo.bash ~/catkin_ws/src/Firmware ~/catkin_ws/src/Firmware/build/px4_sitl_default

[SwiftGust]

@mrivi Adding the line to the .bashrc, now launch file does connect to PX4 SITL, thank you.
Clearly I have missed out these lines and modify accordingly.

# Setup some more Gazebo-related environment variables
. ~/Firmware/Tools/setup_gazebo.bash ~/Firmware ~/Firmware/build/px4_sitl_default

But I'm still having problems, examples are not working properly in my desktop.
It looks like gazebo-ros is not connecting each other yet,
still showing environment variable resulting in
No such file or directory

I did add following in .bashrc file.

source ~/catkin_ws/src/Firmware/Tools/setup_gazebo.bash ~/catkin_ws/src/Firmware ~/catkin_ws/src/Firmware/build/px4_sitl_default

export GAZEBO_PLUGIN_PATH=${GAZEBO_PLUGIN_PATH}:~/catkin_ws/src/Firmware/Tools/sitl_gazebo/build
# Disable online model lookup since this is quite experimental and unstable
export GAZEBO_MODEL_DATABASE_URI=""
export SITL_GAZEBO_PATH=$HOME/catkin_ws/src/Firmware/Tools/sitl_gazebo

I don't know what am I missing.

And the following problems with current status is
I think following problems could go away once as gazebo connects to ROS.

For the global planner, examples are showing

1. Map is not coming into rviz, path planning always fails with goal position is occupied.

For the local planner, examples are showing

2. Looks like transform publisher has some problem regarding publishing image.
   Result in warning messages

         at line 126 in /tmp/binarydeb/ros-kinetic-tf2-0.5.20/src/buffer_core.cpp

However, I can find the frame_id 'camera_link' with

rostopic echo /tf

2. Images are not gets into with rosrun image_view stereo_view stereo:=/stereo image:=image_rect_color
   with sudo apt-get install ros-kinetic-image-view (missing part in doc)
   In Rqt, No image received warning is given

3. Cannot set mode to OFFBOARD when using local planner examples.
   Giving mission in QGC does not avoid obstacles with param 'MPC_OBS_AVOID' enabled(1)

[mrivi]

@SwiftGust Could you please remove this line from the local planner launch file such that the debugging messages are output on the console and copy those here?
Do you get any warning/errors from the PX4 Firmware side? For example, why it doesn't switch to OFFBOARD. Could you copy those here as well?

[SwiftGust]

@mrivi Even with that line removed, problem still presents.
However it does show additional info message

Warning: Invalid argument passed to canTransform argument source_frame in tf2 frame_ids cannot be empty
         at line 126 in /tmp/binarydeb/ros-kinetic-tf2-0.5.20/src/buffer_core.cpp

[mrivi]

@SwiftGust Gazebo isn't simulating the depth sensor so the planner isn't getting a pointcloud.

export GAZEBO_PLUGIN_PATH=${GAZEBO_PLUGIN_PATH}:~/catkin_ws/src/Firmware/Tools/sitl_gazebo/build

this is wrong. Should be ~/catkin_ws/src/Firmware/build/px4_sitl_default/build_gazebo .
Please, set your environment variable from scratch following the instructions.

[SwiftGust]

@mrivi Sorry for the trouble, but today I have set environment variables following instructions
px4 dev docs, instruction here and the sitl_gazebo docs looking for missing part.

I have set earlier environment variable as
~/catkin_ws/src/Firmware/build/px4_sitl_default/build_gazebo
But It didn't work so I built & installed gazebo plugin in ~/catkin_ws/src/Firmware/Tools/sitl_gazebo and have set PATH to that as well with following instruction on sitl_gazebo repo.
So the PATH is pointing gazebo - px4 plugins too, and changing it back doesn't work either.

Environment variable setup in .bashrc is following

source /opt/ros/kinetic/setup.bash
source /usr/share/gazebo/setup.sh
source ~/catkin_ws/devel/setup.bash
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64:$LD_LIBRARY_PATH

export SITL_GAZEBO_PATH=$HOME/catkin_ws/src/Firmware/Tools/sitl_gazebo

[mrivi]

@SwiftGust this looks good. Do you still have the same issue?
Could you check that you have all gazebo packages? sudo apt-get install ros-kinetic-gazebo-*

[SwiftGust]

@mrivi Now it's working!
I manually updated gazebo8 from gazebo7, and from that there was missing part.
with sudo apt-get install ros-kinetic-gazebo8-* gave me this machine is missingros-kinetic-gazebo8-plugins ros-kinetic-gazebo8-ros-control ros-kinetic-gazebo8-ros-pkgs ros-kinetic-polled-camera
and now its working.
I should've suspected this...
Sorry for the trouble, and thank you very much!

[mrivi]

@SwiftGust great!
