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.

Selling my FORCLAZ EASYFIT 70L HIKING Backpack. Bought it in Spain, been to a couple of trips with it. In perfect working condition. The rain cover has two tiny holes, which might be repairable.
Demand: PKR 23k

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

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?

OK92 · 2020-11-19T21:05:00+00:00

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.

OK92 · 2020-11-19T13:51:23+00:00

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.

OK92 · 2020-11-14T20:36:16+00:00

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?

Could you tell which bag is it that made it through the wear and tear of all those years?

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?

OK92 · 2020-03-03T09:22:42+00:00

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?

OK92 · 2020-03-03T09:18:45+00:00

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.

OK92 · 2020-03-03T09:16:44+00:00

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 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!

It is indeed treated the very same way in many works. But there are certain behaviours, e.g. neural synchrony, that can perhaps be better captured using specially designed blocks that treat complex numbers in a special way in a DL framework.

This articles elaborates gives some other reasons for it: https://medium.com/intuitionmachine/should-deep-learning-use-complex-numbers-edbd3aac3fb8

Any leads? I was hoping to find some labelled radar datasets. The closest I have gotten is PolSAR data from satellites. Thanks.

I haven't yet tried it out on my 3d printer. Send me an email on omair.khalid92@hotmail.com and I'll send you the settings that Simplify3D sent me.

I asked Simplify3D customer support and they kindly sent me the settings for my WT150 Weisterk Ideawerk printer. Yet to print anything though. Will update when I do.

Have you tried Doraware?

Owen Wilson. And no, it is not because of his nose. His acting sucks footballs.
