No description provided.

GauravKumar9920 · 2023-02-22T10:49:53Z

How do I set it up manually ?
We are talking about autoparking_v2 right...
can you provide some more details

GauravKumar9920 · 2023-02-23T06:28:04Z

In beta testing I can setup the Gazebo world and spawn, but the web server and docker side of the part how do I build it @pariaspe

GauravKumar9920 · 2023-02-23T06:40:05Z

Also in the current autoparking excersise which is present in the RADI the world and the models aren't spawning.

pariaspe · 2023-02-23T08:35:10Z

Hi, follow the existing instructions. Everything is supposed to spawn inside the RADI. If models are not spawning in gazebo your environment variables may not be set (or wrong set). Check in GAZEBO_MODEL_PATH and GAZEBO_RESOURCE_PATH variables if you can see models and worlds paths.

GauravKumar9920 · 2023-02-24T20:15:31Z

hey @pariaspe , actually I spotted a bug in the Autoparking exercise, the models weren't spawnign in that and I have fixed it. shall I create an issue for the same as the issues is persistent in the og repo ?
Also, just to be sure are we supposed to be working with autoparking_v2 If yes can you guide me to build the same so that it reflects in the locally build docker image as an excersise.

GauravKumar9920 · 2023-02-26T05:34:12Z

Hey @pariaspe any comments 😅

pariaspe · 2023-02-26T12:37:56Z

Hey @GauravKumar9920 , please avoid to ping me twice, I'll answer your questions asap.

I don't spot any bug, since the models are spawning correctly. Anyway, what is your suggestion?

You need to add autoparking_v2 exercise to the exercises database. It is explained in the documentation. You need to build a new RADI first, because the latest doesn't contain the exercise

GauravKumar9920 · 2023-02-27T17:47:15Z

Okkay I will make sure of that.

Actually I checked the following by running the latest RADI, it doesn't has that problem that I mentioned above of not being able to spawn the bot into the arena.
but for the same the code in the latest RADI was different
the code I found on the RoboticsAcademy/scripts/.env by running the latest RADI was -

#!/bin/bash export GAZEBO_RESOURCE_PATH=$GAZEBO_RESOURCE_PATH:/usr/share/gazebo-11:/RoboticsAcademy/exercises/follow_line/web-template/launch/:/RoboticsAcademy/exercises/obstacle_avoidance/web-template/launch/:/RoboticsAcademy/exercises/vacuum_cleaner/web-template/launch/:/RoboticsAcademy/exercises/vacuum_cleaner_loc/web-template/launch/:/RoboticsAcademy/exercises/3d_reconstruction/web-template/launch/:/RoboticsAcademy/exercises/global_navigation/web-template/launch/:/RoboticsAcademy/exercises/car_junction/web-template/:/RoboticsAcademy/exercises/opticalflow_teleop/web-template/launch/:/RoboticsAcademy/exercises/autoparking/web-template/:/RoboticsAcademy/exercises/montecarlo_visual_loc/web-template/launch/

whereas it's diffrent in the Repo.
can you guide me to what branch the RADI:latest is using, cause in the docker-file the branch specified is master.

Also, the issue I mentioned previously still occurs when I build the docker image locally using ./build.sh
So for that, the changes I made to the same for it to work was correcting the path by adding /launch after /web-template in the line.

I have demonstrated it here....

I am a bit confused so kindly help me out with it
Anyways I am working to add the autoparking_v2 excersise to the RADI locally after testing I will update you of the same.

PS: I guess the topic has diverted to the autoparking instead of autoparking_v2 exercise so Shall I create a new discussion or shall we continue it here..

pariaspe · 2023-02-28T09:01:05Z

Hey, you are completely right. /launch is missing after /web-template. Thanks for noticing. Could you open a patch solving it?

RADI:latest should always use master branch.

PS: my bad, I'm renaming this issue 👍

GauravKumar9920 · 2023-02-28T12:00:55Z

well sure but then why the RADI:latest has a diffrent code ?

pariaspe · 2023-02-28T12:11:10Z

Because master branch has evolved since we released that RADI.
I've just uploaded a new RADIv3.3.0 (also new latest). You can work from that stating point and go on

GauravKumar9920 · 2023-03-01T18:30:16Z

Hey I have added the exercise, yet I am facing a bit of issues can you help me out with them...

ango1994 · 2023-03-02T10:15:25Z

HI @GauravKumar9920. The steps to create a new exercise are the following:

Add the exercise to the database wich you already have done.
Create a folder in exercises/static/exercises with the exercise inside. The name of the folder has to be the same of the exercise id you gave in the database.
Create a folder in exercises/templates/exercises with a exercise.html inside. The name of the folder also has to be the same of the exercise id.

GauravKumar9920 · 2023-03-04T08:40:50Z

I have cross-checked all the above mentioned points but the errors still occur.
These are all the files I have changed(compared to the master branch) you can have a look at them..
Also, This is the testing branch Where I am testing all the changes I made.
The errors that occurred -
(one is after opening the exercise )-

one after running (python3.8 manage.py runserver) -

also the files mentioned in the above response -

pariaspe · 2023-03-04T10:10:28Z

Hi @GauravKumar9920 , I've just tested to see what's happening. I faced the same problem. How are adding the exercise to the database? By default, configuration is set as a string while it should be a json. Try, to replace "{}" with {}.

I've also found another bug in instruction.json file. Paths for Autoparking_v2 exercise are wrong, they are skipping static/exercises/ subdirectories. Compare them with old autoparking paths and you will notice easily.

    "autoparking": {
        "gazebo_path": "/RoboticsAcademy/exercises/static/exercises/autoparking/web-template/launch",
        "instructions_ros": ["/opt/ros/noetic/bin/roslaunch ./RoboticsAcademy/exercises/static/exercises/autoparking/web-template/launch/autoparking.launch"],
        "instructions_host": "python3 /RoboticsAcademy/exercises/static/exercises/autoparking/web-template/exercise.py 0.0.0.0"
    },
    "autoparking_v2": {
        "gazebo_path": "/RoboticsAcademy/exercises/autoparking_v2/web-template/launch",
        "instructions_ros": ["/opt/ros/noetic/bin/roslaunch ./RoboticsAcademy/exercises/autoparking_v2/web-template/launch/autoparking.launch"],
        "instructions_host": "python3 /RoboticsAcademy/exercises/autoparking_v2/web-template/exercise.py 0.0.0.0"
    },

GauravKumar9920 · 2023-03-04T10:35:44Z

Thanks @pariaspe !
I will fix the path.
also I will try replacing the same )

GauravKumar9920 · 2023-03-06T13:19:53Z

Hey @pariaspe ,
I have made all the changes but the final one i.e replacing "{}" with {} in configuration can't be done because if I run python3.8 manage.py runserver the error shown above still occurs. I am not sure how to resolve that.
previously the same command was working when I added the exercise but I am not sure to what's happening and why is it giving me errors.

pariaspe · 2023-03-06T13:22:11Z

Hey, I've fixed that on #1962 , so if you build RADI from master again, and you add the exercise as always it should work,

GauravKumar9920 · 2023-03-07T19:59:01Z

Hey, I've fixed that on #1962 , so if you build RADI from master again, and you add the exercise as always it should work,

I checked the same twice once by implementing the changes onto the branch I was testing changes on, and second by cloning the branch where the changes were made
It isn't working :,)

pariaspe · 2023-03-08T14:15:49Z

It should work. @ango1994 tested this morning and merged the branch. Could you try again?

GauravKumar9920 · 2023-03-09T16:00:05Z

Hey @pariaspe I have sucessuflly added the exercise and made the required changes for it to run.
However we I have spotted a bug in the exercise-

The world isn't spawning correctly, shall we work out over here or a new issue ?

pariaspe · 2023-03-09T16:37:14Z

Nice, good work! Let's keep talking here since we are debugging it. Have you checked the GAZEBO_MODEL_PATH env var?

GauravKumar9920 · 2023-03-09T20:57:56Z

Hey, thanks !
I am working on it.

GauravKumar9920 · 2023-03-16T16:36:26Z

Hey @pariaspe @jmplaza , Actually I have my college exams going on, I will solve the issue by next week.

GauravKumar9920 · 2023-03-18T12:42:27Z

hey @pariaspe I am getting this error after running -
docker run --rm -it -p 8000:8000 -p 2303:2303 -p 1905:1905 -p 8765:8765 -p 6080:6080 -p 1108:1108 jderobot/robotics-academy:testing

ango1994 · 2023-03-18T13:14:43Z

Hi @GauravKumar9920 you need to rebuild the base image since there have been changes in the dependencies. "./build.sh -f test"

GauravKumar9920 · 2023-03-18T20:19:30Z

kindly check the PR, I have fixed the world not being able to spawn issue.

pariaspe · 2023-03-19T11:25:54Z

Thanks @GauravKumar9920 , I've merged #1965. I'm able to spawn the world file correctly. I'm able to move the car too.
However, connection closes after a couple of minutes of running the code. Also, JS map viewer is not working while the laser scan seems to be working on gazebo.

GauravKumar9920 · 2023-03-19T12:41:47Z

Okkayy, I will look into it.

GauravKumar9920 · 2023-03-19T16:01:52Z

hey @pariaspe , can you provide me with the code to regenerate the bug.

pariaspe · 2023-03-19T17:01:05Z

hey @pariaspe , can you provide me with the code to regenerate the bug.

I'm building the RADI, launching the exercises and slowly moving the car (HAL.setV(0.1)).

GauravKumar9920 · 2023-03-21T10:56:39Z

Hey @pariaspe , I ran the bot for a few minutes and also restarted the same a few times the connection seems to be fine and didn't get disconnected.

GauravKumar9920 · 2023-03-24T14:06:41Z

about js map viewer issue can you elaborate.
ps: I am done with exams, I can contribute actively.....

Amglega · 2023-03-26T09:55:48Z

I changed the topic in the gui.py to "/catvehicle/front_laser_points" and the map shows the front laser at first but it does not get updated properly when the car starts moving:
