I have this problem when I'm trying to move the sliders it is near impossible to move them anywhere, the gif below probably doesn't display so here's the imgur link to an example of a non responsive joint_state_publisher gui non responsive joint_state_publisher gui

This is on Kinetic, Xenial 16.04. Can anyone explain why and help me resolve this? I'm considering just creating a gui with rqt or just control it through a script if I can't resolve the above :)

If you can convert the gifv to a real gif, it should display fine.

You don't tell us, but you probably have another entity in your system publishing joint states. The joint_state_publisher will then set the sliders to those values. You can try and drag them, but the next incoming message will set them right back to where they where.

If you tell us a little more about the configuration of your node graph, we might be able to spot what is wrong.

Also: the joint_state_publisher UI is not meant for 'controlling a robot'. The only reason that UI exists is to provide you with an easy to change 'debug interface' to a joint states topic (ie: you use it when you have no real hardware which publishes real joint states). In a system with real hardware, the joint_state_publisher is used, but rarely with the use_gui parameter set to true.

I know that the joint_state_publisher isn't meant for 'controlling a robot'. I'm writing a walkthrough for a friend of mine so we can build a robot together. The reason I asked was because I suspect that Kinetic distro might have something to do with it. node graph.

Where is RViz in the graph you posted?
