Hi everyone. Actually I'm trying to study the tf_web_republisher code, and I find some difficulties about understanding how tfClient on roslibjs works with tf2_web_republisher. It seems that TFClient just listens to TF service; it does not send a goal nor receive a result. Isn't it? if is it so, what is the diffrence between this example visualizing a urdf file and this one writing a tfclient thank you very much

Actually I want to know how long would take a tf to "travel" from the server to the web page in the visualizing urdf example by synchronizing clocks will help me to figure it out. So the main purpose is to have travel time inside a websocket

I found this post wherein it's explained how to measure the diffrence between the client and the server clocks. I suppose that I can use it to calculate "travel time" of tf in a websocket. Isn't it?

Hello everyone I was trying to measure time that would take a tf from the server to a client web page inside a websocket communcation. A kind of a ping. I was thinking about synchronizing the server and the client clock, but a ping is also a matter of milliseconds. Any ideas please!

Hello every one, I'm beeing struggling these couple of days about making a 3D model moving in a web browser. I know that I should use a tf client to read the information about /cmd_vel from the real robot (or from gazebo) publishing it and sending it to the model but I don't get the connection between : URDF, base_frame, (world frame?), state publisher, tf listener, tf publisher, tf2_web, rosAria, tf_client All of these familiarities I got them separately but I don't know how to proceed to get them work together. Please some body to illuminate the all thing. Thank you in advance,
