This would be great!

@dheera do you think you might merge this one?

[dheera]

Thank you! I was meaning to implement a more general Publisher infrastructure and then do a joystick on top of that, since there may be robots that need to publish things other than /cmd_vel. I'll look into this.

Are there users of rosboard who are actively using a fork of it to joystick their robots? Would love to hear input.

Looks really good! I will try this recently and give some feedback.

@dheera it is quite useful, I also think that it could be improved by adding another "joystick" so you can control omniwheel robots, too.

About /cmd_vel topic, I think it could be possible to add the list of required topics as a parameter or scan all twist_msgs topics by looking all subscribers node.

I hope this could help

@dheera any more thoughts on this?

Hi @surpace0924! This joystick feature is really awesome. Unfortunately automatic merge is not possible now.

Do you think you could adjust your code to make it compatible again?

For anyone who is interested, I rebased this PR and added support for the /joy topic and physical joysticks.
