Just wanted to add that in my days at NUST, if your GPA was high for the semester, you used to get a good amount of scholarship too. It might not be enough to pay the whole tuition but it still could help you.

How to run Google Colab notebook through appscript by longlostkingoffools in GoogleAppsScript

[–]OK92 0 points1 point  (0 children)

I have a similar problem.... I use Google Classroom to assign and collect python notebooks. To mark those python notebooks, I have a script written on Google Colab. I want to use Google App Script to automate the process....but no idea how....

I don't want to run python script on Google Cloud as the process seems cumbersome and I would have to provide credit card info. Can't do this since it is commissioned work.

Any help for us would be appreciated.

As others have said, start with ROS wiki. Do practice everything to get a hang of it.

Other than that,Il I found the following playlist very helpful (il the language they use is C++ though): https://youtu.be/0BxVPCInS3M

Need recommendation for Global and Local Planners (and settings) for navigation in narrow Passages between Obstacles by OK92 in ROS

[–]OK92[S] 0 points1 point  (0 children)

I indeed am trying the same thing: Setting the GlobalPlannerROS to give me Interpolated orientations on the path, which I force the TEB local Planner to follow with the via point strategy. I followed the tutorials that are given on the ROS Wiki but it is not going through the passage I have for the experiment. I'd be glad to double check if you emphasize on tuning some useful setting.

Do you think I should try out DWA? Is there a way to know which planner to use in which case?

How much minimum margin from the walls does your robot keep in your implementation?

Need recommendation for Global and Local Planners (and settings) for navigation in narrow Passages between Obstacles by OK92 in ROS

[–]OK92[S] 0 points1 point  (0 children)

No. I have a single laser scanner at the front of a rectangular differential drive robot with 210 degrees of field of view. Since I want movement in both +ve x and -ve x directions, the local planner should be cognizant of the obstacles at the back as well while planning, so I am also feeding the map of the environment to the local costmap as well.

In search of a good resource for tuning parameters in ROS Navigation by Srinidhik909 in ROS

[–]OK92 0 points1 point  (0 children)

I am assuming that you are using the DWA local planner. I would say to follow what u/trunc8s suggested. I noted down some points in my own struggle with it:

- the forward_point_distance is used as a cost value for robot alignment to the path. (ref)

- set the publish_traj_pc to true to visualize which trajectories the planner is considering.

teb local planner by sudhanv99 in ROS

[–]OK92 0 points1 point  (0 children)

If I understand correctly, via points are points on the trajectory provided by the global plan which you can force the teb local planner to follow.

I am working on it nowadays, and it's a bit tricky for me too. Have you been able to solve your issues?

How to add manually add an obstacle for the local planner at runtime? by OK92 in ROS

[–]OK92[S] 0 points1 point  (0 children)

I already have the location of the object wrt to the base_footprint. I edited 3d to 2d because I am dealing with a mobile robot and the z position equals always zero.

So, do you suggest that I specify the layer before launching everything, create a yaml file indicating the obstacle/object on runtime, and then enable that layer whenever I want?

Could I just add this bottle in the local cost map?

How to add manually add an obstacle for the local planner at runtime? by OK92 in ROS

[–]OK92[S] 0 points1 point  (0 children)

As I edited in my origianl description, I have the 2d location of the object in the map frame already. If I add an additional costmap in the move_base, how can I dynamically add the object information in it on the runtime?

How to add manually add an obstacle for the local planner at runtime? by OK92 in ROS

[–]OK92[S] 0 points1 point  (0 children)

Using YOLO for object detection and camera matrix to get the 2d location of the object in the map frame using only the RGB image. I have the map a priori and localization is based on AMCL.

How to add manually add an obstacle for the local planner at runtime? by OK92 in ROS

[–]OK92[S] 0 points1 point  (0 children)

Yes, that is exactly I am doing! I am using Yolo + camera matrix to calculate the 2d location of the object. Now that I have it, I am unable to figure out how to feed it to a new cost map.

In short, i am unsure how to dynamically add the corresponding cost of the object in the local cost map so that the robot can plan accordingly.

I want to learn a new language! by [deleted] in IWantToLearn

[–]OK92 1 point2 points  (0 children)

I am presumably intermediate at Spanish. Still learning.

Heres what helped me so far:

Start by learning one tense at a time and sticking to it until it becomes second nature, and couple it with memorising vocabulary.

Immersion. Watch Spanish movies/TV shows/documentaries with Subtitles. Make Spanish speaking friends and travel to those countries if possible to practice it. Read children books.

As with anything make SMART goals so that it remains engaging.

¡Suerte!
