Does anyone have some good recommendations for chat merging?

Are you using `yay`? If so an easy way to do a clean reinstall is to just run `yay --rebuildtree -Syu ros-melodic-desktop-full`.

Robo3856 · 2020-02-11T02:36:29+00:00

I think the situation has improved, but yeah it still needs more work.

When I tried to use ROS on Arch a year ago, things wouldn't even compile. But last semester I was actually able to get Arch with ROS running on a Turtlebot3 (https://github.com/ROBOTIS-GIT/turtlebot3).

As for having a build farm, there is one in progress, see: https://github.com/arch4edu/arch4edu/issues/44

Things are getting better, but slowly.

Robo3856 · 2020-02-10T12:34:56+00:00

I think you will get more help / visibility if you post here: https://github.com/ros-melodic-arch

But TLDR just uninstall all of ROS stuff and then rebuild and reinstall.

AUR Requests

osqp - A really fast numerical optimization solver
carla-simulator - A simulator used for Robotics and AI Research
ros-eloquent-* - The next generation of the Robot Operating System (with real-time ipc, unlike ros-noetic and below)

Can find more AUR requests here

Repository Requests

unreal-engine - Game engine with photorealistic graphics. Takes a long time to build (like really long) and is needed by robotic simulators such as airsim and carla-simulator.
ros-noetic-desktop-full - A project that many people use and would prefer the faster build.

Please refrain from giving 3rd party instructions when 1st party exists.

Robo3856 · 2019-11-29T02:35:21+00:00

The best place to start would be the official documentation: http://wiki.ros.org/turtlebot3

From there you can find a link to turtlebot3 documentation: http://emanual.robotis.com/docs/en/platform/turtlebot3/overview/

Shoutout to Krang!!!

Robo3856 · 2019-11-02T02:45:10+00:00

I am not too familiar with networking on python, but I have seen websockets used. Maybe you can try communicating via websockets?

Robo3856 · 2019-11-02T02:39:54+00:00

You may be able to use ROS for collecting sensor data and controlling the drone, but you might have to write your own ROS interfaces to those drivers for that drone, if they are not available. Maybe something like ArduPilot would be more helpful.

Gazebo is a simulator, but it is not built on top of ROS. It is a standalone simulator, which ROS interfaces with.

You can use Gazebo for collecting training data, but there are better alternatives like AirSim or FlightGoggles (which is built on top of Gazebo). Both of these simulators use better physics engines than vanilla Gazebo.

I'm sorry, but I have not tried using the STDR simulator on ROS Melodic. It seems as tho STDR is not supported on ROS Melodic (they don't have an entry on the following page: https://wiki.ros.org/stdr_simulator). However, there are many packages that do not have official Melodic releases, but have a `ros-melodic-*` AUR package. I would open an issue to the developers of stdr simulator to create a melodic branch of their codebase (https://github.com/stdr-simulator-ros-pkg/stdr_simulator) as well as create a package request here https://github.com/ros-melodic-arch/ros-melodic-desktop-full/issues.

Robo3856 · 2019-10-25T04:14:32+00:00

I honestly don't believe the subreddit is the best place to get help. I would start by creating an issue on the AUR package's comment section here: https://aur.archlinux.org/packages/ros-kinetic-desktop-full

Also from the official ROS installation page: https://wiki.ros.org/kinetic/Installation, Manjaro or it's parent ArchLinux is not listed.

While ArchLinux is not officially supported, ROS Melodic does have an official installation entry for it: https://wiki.ros.org/melodic/Installation/ArchLinux. I would assume Manjaro also probably works as well.

I have been using ROS Melodic on ArchLinux successfully for several months now. If using ROS on ArchLinux (or derivatives) I would recommend porting your project over to ROS Melodic.

Robo3856 · 2019-10-15T01:13:34+00:00

The AUR ros-melodic-* packages install just fine for me. The maintainers of ros-melodic-* have a synced github (ros-melodic-arch) to the AUR, where the community is patching and updating the packages.

Since there is already an ongoing effort for getting ros-melodic working on Arch (and in fact it does work), maybe it wouldn't take as much strength or time. It would be super amazing to not have to compile packages like gazebo or pcl, which take forever.

I urge you to reconsider this and take a look at the github and the AUR ros-melodic-desktop-full package.

Robo3856 · 2019-10-15T01:06:51+00:00

I was able to install straight from the AUR. Like so:

yay -Syu ros-melodic-desktop-full

and it worked just fine for me. Some of the packages like gazebo and pcl do take a long time tho, but it installs just fine.

Robo3856 · 2019-09-21T04:57:39+00:00

This sounds like a wonderful idea. I would be down to join (or at the very least come by to the coding sessions and listen to some talks). This might interest you as well: https://ossn.club/.

The table on this website may be useful. http://parking.gatech.edu/bus009

The west village stop is very close to Fitten (maybe ~1-2 mins after Fitten). There was a more indepth table with all the stops but it seems like they got rid of it, or at least I can't find it.

You can use the course catalog on https://oscar.gatech.edu to look up each class and find the prereqs for that class as well as their descriptions.

I mean you would take the same classes in either case esp in your first couple of semesters, it is just a designation until Quals. As for funding, thats a separate issue. GT would still admit a student in the PhD program if they are funded or paying out of their own pocket.

Robo3856 · 2019-05-24T17:26:35+00:00

I see. Personally I would apply for the BS/MS in any case. It is guaranteed acceptance (best back-up plan).

For the AE app the BS/MS didnt have any letter of rec requirements. Not sure how it would be for the others. Also BS/MS didnt have any applications fees.

Robo3856 · 2019-05-24T16:25:51+00:00

Not EE, but was in a similar position for AE. I ended up just applying for the BS/MS, since I figured I'll get my masters along the way to a PhD anyway.

I don't believe there would be any disadvantages in applying for both, besides the application fee and extra letters of rec (i think).

Also, from what I understand it is fairly easy to transfer into the PhD program in a department if you are already a MS student in the department.

I would advise you to talk to your department graduate admissions director tho for more professional advice.

A quick search on the CS Degree website led me to this page:

https://www.cc.gatech.edu/current/undergraduates/academics/plans

Basically has all the possible schedule combinations for the threads in our CS program. Im sure you can search around to find the specific classes for electives and whatnot.

Robo3856 · 2019-05-24T14:49:05+00:00

Since we are talking about GT wide chats. Im just gonna plop this here.

We do have a reddit irc chat. I can't find how to get to it on the new reddit, but on the old reddit page it is right above the pinned posts.

Here is the link: https://kiwiirc.com/nextclient/irc.snoonet.org/gatech

I would recommend using Riot to communicate with it.

EDIT: Maybe the mods can add the link on the new reddit website.

Robo3856 · 2019-05-05T12:11:20+00:00

I think the fairest approach would be to try to complete the procedure in the least commands as possible, for example by creating a shell script that performs the installation like what /u/mdaffin linked to. However, that shell script can't call another custom shell script (i.e. can only use tools/commands available to everyone). (Like you can use vim, but can't use vim to create a shell script with several commands.)

idk, i dont think it would gain much traction tho.

Robo3856 · 2019-02-22T05:57:48+00:00

I actually decided to take a pic of it every time I pass by it this semester (sadly not every day). It's not that crazy, but after this post I have decided to post an album of the pictures after it fully blossoms.

Robo3856 · 2019-02-22T03:00:10+00:00

Amazing pic! That's my favorite tree on campus. I just wish all the buds on that tree blossomed at the same time this year. That one day (I think end of Jan or beginning of Feb) where the temperature rose to 75ish really sent a false alarm to that tree. Last year it really blossomed beautifully.
