Can't use rviz with maps on the project laptop #123

Open takluyver opened 8 years ago

takluyver commented 8 years ago

Rviz complained the the aerial maps plugin couldn't be loaded. I guess the package needs to be installed on that laptop.

Yes you just have to follow the wiki page: https://github.com/Maritime-Robotics-Student-Society/sailing-robot/wiki/Rviz:-2D-plot-of-our-boat

Thank you! On Wednesday, let's do that on the project laptop, check that it's working, and then close this.

Also since you probably don't have a data connection during lake test, you should run a simulation with the lake waypoints beforehand for rviz to download map tiles. Then you'll be able to use it offline (you can always backup the folder ~/sailing-robot/src/rviz_satellite/mapscache somewhere else in case the cache gets deleted).

I have followed the instructions from the wiki and got the plugin loading, but it doesn't show anything. There's a warning saying "No map received". But I'm also not sure if I'm using ROS right, because all my rostopic echo commands aren't working against the rosbags.

Is rviz working correctly during simulations ? And for the map to show you need an internet connection so if you are connected to the pi maybe it is not possible (you'll need to run a simulation beforehand to dl maps to have them in cache)

I was trying to replay a ros bag file, and I was connected to the internet. I'm not there next week, but hopefully someone else can test rviz with the simulator on that laptop.

I have never tested rosbag playback with rviz, I'll give it a try.

EDIT: I have just tested that on my laptop, and it is working great, the problem is probably with the ros installation, in the end the node debugging_2D_plot only needs the /position topic.
