Hi there By the time I came to this question, I got a lot of great information on the internet, but the combination of 'rosbridge' and 'robot web tool' or 'ros2djs' is just displaying the generated map The I want to see the process of gmapping generating a map like rviz in real time on the web. Please let me know the solution for that. Please excuse my poor English.
See the answer to this question: https://answers.ros.org/question/3150...
I put working code up that displays the map in webbrowser locally or remotely.
Of course all that code started as samples from robotwebtools.org and ROS tutorials - but I admit I have not tried it while gmapping.
So you had me curious. Now I have tried it with gmapping and it works.But you need to tweek the code I linked to in earlier comment to continuously update the map. Add ", continuous : true" to the gridClient
var gridClient = new ROS2D.OccupancyGridClient({
ros : ros,
rootObject : viewer.scene,
continuous : true
});
The map updates every 15 - 30 seconds on my old laptop running everything..
This is all I was looking for! I can’t thank you enough:) you and @ahendrix made me notice OccupancyGrid. Thank you and so so much.
I am using your html code give in the link https://answers.ros.org/question/3150... for gmapping of turtlebot3_world.The page is displaying the generation process of the map but it is not showing robot's position on that map..... Looks like the roslibjs is not able to subscribe /robot_pose ..... On the console I see 'Before callback' and 'creating robotMarkr: ' but I didn't saw 'In pose subscribe callback','Got Pose data:' and 'Pose updated: ' ........please resolve my problem @billy@ahendrix@justinROScolleage
What commands are needed to display the robot's position on the map? When I run the page, the square where the map should be is empty @Addy_thegreat
Clone rosbridge_suite and mjpeg_server from github at first @saintdere

rviz is just subscribing to the
/maptopic and displaying it as gmapping generates updates. I haven't used the various ROS web tools that you mentioned, but you should be able to have them subscribe to the/maptopic and display updates in real time too.thank you for your comment! Yes, I just wanna subscribe to the /map and display that on the web! But I cannot find the way to this.
I don't know much about javascript or the ROS web tools, but some quick browsing of the documentation brought me to http://robotwebtools.org/jsdoc/ros2dj... , which seems to be able to subscribe to an occupancy grid and display it. I wasn't able to find a working example of that in a quick search, but there have been a lot of talks and documentation about the robot web tools packages, so I suspect that if you look hard enough, you'll be able to find something.
Looks like I was a bit slow; @billy's comment includes a working example of the class that I linked to!
