Hi!

What notebook would you recommend for ROS development? Would MacBook Pro work good?

I work with ROS a lot in my projects. I also often need Gazebo, so Parallels on Mac would not efficiently, and I need either install ROS on MacOS or use Ubuntu on MBP. Does ROS and Gazebo work same at MacOS as under Ubuntu currently? Do you have experience using Ubuntu with ROS on MBP or what are your other recommendations?

Thanks!

Update: So there are 2 Alienware recommendations and I am not sure about MBP. Anybody use it? Because Alienware seems to be not very compact. Maybe we could make some poll "What notebook do you use for ROS" here.

Hi!

I need to make universal CMakeLists.txt, able to build package with ROS or not. So I need some conditional variable to detect, that package could be build with ROS:

if(SOMEVAR)
   set(USE_ROS true)
endif()

if(USE_ROS)
   find_package ...
   catkin_package ...
endif()

Thanks!

Hi!

Anybody has solution for this problem?

When I moved to Ubuntu 16 and ROS Kinetic from 14 and Indigo, I couldn't use QtCreator because of long latencies of GUI, it is very slow, when using autocompletion, going to definitions, refactoring, copying and so on.

This is common issue on two my computers and for my teammate.

For Ubuntu 14 and ROS Indigo it worked perfect.

Also it works OK for non-ROS projects.

Thanks!

Thank you! I am not alone) Installed 4.2.2 from website and done configuration according http://wiki.ros.org/IDEs#QtCr

I have big robot with 360-degree LIDAR. LIDAR is set in a way, that some robot construction elements are on the LaserScan data. Thus they are at costmap. So robot become an obstacle for itself :-)

I think, I should be common problem, but I don't know the simple way to address this. Should I substitute LaserScan values for certain angles, at witch it sees itself to inf? Or I must separate 1 360-degree scan to 4 separate scans, that eliminating the problem angles? Or I need in some way configure costmap? Actually, robot elements are inside footprint and must be cleared?

I'm able to use qt_ros, but it creates package depending on Qt4, but I need Qt 5.1 or older to use QSerialPort. How can I do it? Is it a bad idea?

I'm using AR.Drone with Flight Recorder (witch enable geolocation using the GPS module).

I installed ardrone_autonomy and very pleased with it. But there is no GPS data in topics published.

However, using QGroundControl, I can connect to AR.Drone and get GPS data in GLOBAL_POSITION_INT packet, so I can get GPS data in my program with MAVLINK.

The problem is that I can't use ardrone_autonomy and MAVLINK connection simultaniously. When I start ardrone_autonomy, I loose connection in QGroundControl (MAVLINK).

So my question is about possibility of reading GPS data from AR.Drone with ardrone_autonomy or using ardrone_autonomy simultaniously with MAVLINK connection?

I think, I solved this problem for myself. The issue was that Rviz doesn't correctly use /move_base/global_costmap/costmap_updates (of map_msgs/OccupancyGridUpdate type), so setting parameter always_send_full_costmap: true to costmap does the job.

If I disable and then enable costmap view in rviz, it updates. But rviz itself doesn't translate cosmap update, it draws it with old origin.

It even happens for husky_navigation example.

How could I configure rviz to view rolling-window cosmap with moving origin right?

Here are 2 screenshots - first with costmap view shifted and second with correct visualisation after disable and then enable costmap view in rviz:

I use ROS Indigo, Ubuntu 14.04. I tried at different computers, on VM and without, at just-installed ROS with same result.

Thanks

I tried, but it says "CMake Error at /home/roman/Qt/5.2.1/gcc/lib/cmake/Qt5/Qt5Config.cmake:3 (message): Qt5 requires at least CMake version 2.8.9 Call Stack (most recent call first): test/CMakeLists.txt:9 (find_package)". ROS Hydro Medusa uses CMake 2.8.3...
