Any documentation on ROS specific feature, e.g widgets? about jupyter-ros HOT 5 OPEN

Other than the two screenshots in the readme, is there any documentation for the capabilities of this wonderful package?

Hi,

indeed documentation is currently quite lacking. Best way is to look at the notebooks and read the source code (for the moment).

We'll need to work on that!

there are three classical widget functions: jr.subscribe, jr.publish and jr.bag_player and jr.live_plot

and then there is the ros3d suite with all the widgets you find in this file (mirroring roswebtools.js capabilities):

https://github.com/RoboStack/jupyter-ros/blob/master/jupyros/ros3d.py

The usage across widgets is pretty much always the same, so you can extrapolate from the examples (add objects to a view model).

However, some important fixes are coming in with #17, so just to let you know :)

Thanks... There are multiple things called sidecar. How do I install it so that I can run the 3d widgets? Also the comment in the laser notebook says "Make sure that the websocket rosbridge is running on your host computer, and that you publish a laser scan on the /scan topic." I am not sure what that means. What if I have a similated gazebo robot publishing on /scan, won't that be the same? Thanks!
