ROS tools

ROS has a variety of GUI and command-line tools to inspect and debug messages. Let's look at some commonly used ones.

Rviz (ROS Visualizer)

Rviz (http://wiki.ros.org/rviz) is one of the 3D visualizers available in ROS to visualize 2D and 3D values from ROS topics and parameters. Rviz helps visualize data such as robot models, robot 3D transform data (TF), point cloud, laser and image data, and a variety of different sensor data.

rqt_plot

The rqt_plot program (http://wiki.ros.org/rqt_plot) is a tool for plotting scalar values that are in the form of ROS topics. We can provide a topic name in the Topic box.
