ROS Nodes and Topics
SOLUTION:
- Robots may be very different in form and function, but they all perform the same high-level tasks of perception, decision making, and actuation.
- The parameter server acts as a central repository where nodes on a system can look up parameter values as needed.
- Nodes pass messages to one another via topics, which you can think of as a named bus connecting two nodes.
- A single node may simultaneously publish and subscribe to many topics.
