Hi can someone please explain to me how to start rcremoteserver and rcmanagersimple?

Can somebody tell me how long proposal should be, are there any restrictions on proposal length?
Bhavishya Pandit
@bhav09

@Spnetic-5 A proposal can be of any length but it has to be good in terms of content that is being provided, your knowledge of the subject and the project you are submitting a proposal for. It will always be good to write a proposal keeping the perspective of a mentor. Nonetheless, you can learn more about writing a proposal from the following links:

Guidelines to write a proposal:
https://google.github.io/gsocguides/student/writing-a-proposal#:~:text=Summarize%20your%20education%2C%20work%2C%20and,like%20should%20definitely%20be%20mentioned.

Thank you very much!

hey!
I was thinking of writing a proposal for "Deep Reinforcement Learning for precise robot grasping and object manipulation"
and I was wondering if the mentors were willing to share some pointers and/or tips for writing a good proposal.
thanks!
Bhavishya Pandit
@bhav09

@ThChatz, you can write a proposal and mail it to the mentors of the project. In that sense, not only your proposal would be reviewed but also would save a lot of your and their time. The best part about this approach is that the mentors will give you feedback that will help you improve your proposal in terms of content and representability.

You can find the email ids of the mentors of your project from this link:
https://robocomp.github.io/web/gsoc/2021/ideas/
Hope this helps :)

Hello, I have sent my draft proposal on GSoC website, sent a mail also for Project Idea <Computer vision for detecting elements of a vehicle’s environment with RoboComp>. It's been 3 days since then, I haven't got any review or reply from mentors. How should I proceed?
Bhavishya Pandit
@bhav09
@Spnetic-5, now when you have drafted the proposal on GSoC's portal, it will be taken as an application and will not be reviewed. For reviewing you had mail it to the mentors either on their mail ids or would have texted them on gitter. Nevertheless, mentors would surely review your application when the reviewing period starts on post 13th April.

Hi, is making a PR(Pull Request) in RoboComp necessary for GSoC selection?
Bhavishya Pandit
@bhav09
Hey @abhishek-ep19, raising a PR is an emblem that you have gone through the code base and are willing to contribute to its enhancement. It is always a good gesture and it adds on if you do so. However, if you have worked on the project that you are applying for and mention things related to research that you have done would be of equal importance. In the end, it is about how you are contributing to the organisation and how are you willing to keep doing it.

Are we supposed to install the build tools for RoboComp separately?

What is the use of Flexible Collision Library in Robocomp?
Esteban Martinena Guerrero
@orensbruli
@GarvTambi I would suggest looking into robocomp commit history and look who have worked the most on an specific piece of code if you have doubts about it. That way it would be easier to point your questions to the ones who can know the most about it. Robocomp is huge and I can't answer many of your questions. Sorry.

Are we supposed to install the build tools for RoboComp separately?

I don't think so. Why?

I got this error when I run make command in terminal. Can anyone please tell me how can I fix it.

@orensbruli
remove with sudo the build directory of your component
create it again with your user
and don't use sudo for any of the commands to compile your components
let me know if it helps
GARV TAMBI
@GarvTambi

remove with sudo the build directory of your component

Yes it helps
Thanks man!!

While building individual components for RoboComp, is it normal to explicitly ask cmake to link RoboComp specific shared libraries like libqmat.so and libinnermodel.so to target component executables? Or are these libraries implicitly linked to all targets by the build system?
Ashwin A Nayar
@nocoinman
I was trying to build a component from source and had to tweak the component's CMakeListsSpecific.txt file add explicitly link qmat and innermodel to the targets. Just wanted to clarify if this is something to be added to the component's cmakelists or an issue with the build system itself
Esteban Martinena Guerrero
@orensbruli
It's probably my fault. I have been updating cmake files to bring old ones to a more modern way of writing cmakelists. In this process, I have had to change some things about how and where the robocomp libs are generated and installed. I also work with robocompdsl, so if you give me some examples of your tweaks I would try to add to the CmakeList generation of the components.

Can anyone help me with using robocomp with CoppeliaSim? I followed the instructions shown here. Running the viriatoPyRep bridge is throwing an IndexError

While developing a component I am getting the message There is no such "robot" node in the shell continuously. Is there anyway I can list down or get info about the various nodes running in robocomp?

Hello @Varun270

@Varun270
I am a beginner in open source and have fixed some documentation and typos before but have never made changes in the actual codebase. I am trying to understand robocomp repository but am a bit lost. Can you guys guide me on how can I get started in order to contribute to this repository?
I have tried understanding the issues but not able to understand what's going on?
Esteban Martinena Guerrero
@orensbruli

Thank you @Varun270. Have you followed the installation process for robocomp? And the tutorials?
https://github.com/robocomp/robocomp#installation
https://github.com/robocomp/robocomp/blob/development/doc/README.md

Those would be the first steps to understand Robocomp.

Bhavishya Pandit
@bhav09
Hey @Varun270, glad you joined! As a beginner, you can always start by understanding the content written in readme files. Contributors always make sure to keep it as comprehensive as possible. I can understand looking at that a codebase of RoboComp can be overwhelming so here it will be better for you to focus on one feature first and understand it. A progressive approach will always give you the best results! You can always start learning from tutorials and RoboComp has its tutorials mentioned.
Varun Shrivastava
@Varun270
@orensbruli Thanks for the guidance I will make sure to watch all the tutorials.
@bhav09 Thanks mate for your concern I will keep that in mind.
