Writing a publisher node

asked 2013-07-29 23:04:27 -0600

This post is a wiki. Anyone with karma >75 is welcome to improve it.

How do I write some publisher node that computes some coordinates and publishes their position.

How do I transform from a fixed frame like /world to another frame of my choice like /sat1/base_link. I believe tf broadcaster is required for it. Can anybody help me in this.
