How to fix this error?

Hi @ZeoDarkflame , the error information shows no Qt platform plugin could be initialized. Maybe you can try to reinstall the application to fix.

You can export QT_DEBUG_PLUGINS=1 and export QT_TESTING=true before running the previous command and you would get much more information about what is happening to qt. Probably some library is not installed.

I am planning to participate in gsoc-21. Is there any priority order for gsoc-21 ideas?

Hello @ZeoDarkflame ,
Regarding your question, the main motivation behind this project can be summarized as follows :
  • Having an complete perception and grasping pipeline that relies on learning (more specifically Deep Learning).
  • Extending the pose estimation and grasping project done last year to have full control on the robot arm (without using the simulator IK solver).

@ZeoDarkflame
@DarkGeekMS ,
I guess I understand why you are gravitating towards RL, one more thing I would like to ask is, is this project going to include implementation of a few SOTA algorithms and comparing them in this setting, or its about achieving the best possible results on the arm.
Plus, would you recommend that someone like me take up this project, I recently finished studying Policy Gradient Methods, but am yet to read papers on the famous algorithms like A3C, SAC etc.
Mohamed Shawky
@DarkGeekMS
I think the project timeline won't allow the student to implement more than one algorithm along with its refinement and integration. So, I think it would be better to review the related literature and stick with one methodology.
Moreover, anyone with some RL knowledge and familiarity with basic Deep Learning should be good to go with this project. However, the more knowledge and understanding of literature you have, the more chance you have of landing a good proposal for this one.

When should i start preparing a proposal ??
Esteban Martinena Guerrero
@orensbruli
@vkrm1612 Most people is already preparing their proposals and sharing with mentors to get it reviewed, so you can start whenever you know what ideas you are interested in.

Am i late ?

No, I don't think so!
The official dates are
March 29 18:00 UTC Student application period begins
April 13 18:00 UTC Student application deadline

I wonder what should be included in the proposal. Since on the RoboComp webpage of GSoC, it says we only need submit schedule and some codes. Do I need to add some ideas of my own to the proposal? Would that be better?

Hey guys,
I was following this tutorial (https://github.com/robocomp/robocomp/blob/development/doc/DSR-start.md)
But in the section where we are supposed to navigate to idserver folder and make it (step 3 and step 4), I am getting this error

ohh, nevermind this, I got through this by simply installing Fast-DDS
but now I have a different error...

Hello @ZeoDarkflame it seems that you didn't compile and install the DSR class

@pawanw17 , you're right I did'nt, Its working now,
Thanks a bunch

I am having a doubt that for the project "Computer vision for detecting elements of a vehicle’s environment with RoboComp", do we have to create in a component in robocomp-robolab/tree/master/components/detection?

@Kanav-7 @orensbruli @vaibhawkhemka Hello,while running the test component for my client part. I came across this error. The error says model not placed in correct directory but actually I placed that model in assets folder and also I gone through the code whether the path is mentioned correctly or not. Everything seems fine but I can't understand why this error is popping up. Do we need to change the name of the file or should i need to do anything else
Vaibhaw Khemka
@vaibhawkhemka
@SAIGANESH02 I think detection_mediapipe is not being imported in the specifworker.py. So, instead of using "import detection_mediapipe", use "from detection_mediapipe import * ". It must solve the issue.
SAI GANESH N
@SAIGANESH02
Thanks bro. Now it recognized but while running the test component it says "Error taking camera feed. Make sure Camerasimple is up and running" but my camerasimple and handGesture component is running parallely in other terminal. Why is that so ?
Vaibhaw Khemka
@vaibhawkhemka
@SAIGANESH02 enable your camera.If it doesn't fix the issue, please share a screenshot of the error to get idea about the error.

@DarkGeekMS Hey,

I am actually interested in RL based robotic manipulation project and have already done the literature review. I was wondering if there is any specific research paper related to RL-based robotic manipulation that interests you most? That would be helpful

I have a doubt regarding LearnBlock that does it uses robocomp-robolab/components? I am a little confused about that since LearnBlock contains learnbot_dsl/components, but previously GSoC students added components in robocomp-robolab/components for eg, emotionrecognition. Any resource regarding LearnBlock will also be helpful.

The main idea is to put in robocomp-robolab any component that could be useful for more than one project. And keep the components tightly related to a project in their own components folder and repository...

Hi, everyone here Fabio from Italy, I'm studying Computer Science at the University of Milan-Bicocca
I was looking at the project for Depth Estimation using a Monocular RGB camera, does RoboComp have a good dataset or the project will use others like the one from Kitti?
Mohamed Shawky
@DarkGeekMS
@umerjamil16 Hello,
I'm currently considering these two papers :
Mohamed Shawky
@DarkGeekMS
@JackFrost67 Hello,
We are currently considering open-source datasets. Also, they should be more related to indoor activities, unlike KITTI.
Some options are :
  • YCB Videos Dataset : mainly used for pose estimation but contains depth information as well.
  • NYU Depth Dataset : a commonly-used dataset for indoor segmentation and depth estimation.

When I run rcis simpleworld.xml command in terminal ....why robot is not moving , it is an static position. Pleae help me to sort out from this.

Thank You.

try to remove any *.ice in tmp, you will probably need to do it with sudo. It looks like ice files have been generated with root permissions somehow.

@GarvTambi You need to start keyboard component in other terminal after you started simpleworld.xml this make robot move using your keyboard

Thanks bro. Now it recognized but while running the test component it says "Error taking camera feed. Make sure Camerasimple is up and running" but my camerasimple and handGesture component is running parallely in other terminal. Why is that so ?

Hello,
I solved that previous error by setting maximum memory size in ice configuration. Now the test component is working fine and I can see that classes are detected in terminal but I can't see that camera window (the handGestureClient window) which put these bounding boxes on the hand and say which class it belongs to, but in handGesture and HandGestureClient terminal windows I can see the hand got recognized as a statement. So, What to do in order to make handGestureClient window camera to work ?
Thank You
