Hi,
my question is related to the code of odometry msgs at http://www.ros.org/wiki/navigation/Tu...
How can I visualize a series of odometry msgs in rviz. How do I have to configure rviz to get a sequence of arrows illustrating path and velocity? If I start the small example together with rviz (fixed frame = /base_link) I see with target frame = <fixed frame=""> one stationary arrow?
Best wishes

Try setting your fixed frame to /odom or /map (if you have a map). In my setup, you won't see any movement of the arrow when the fixed frame is set to /base_link. I've attached a snapshot from RViz after rotating the robot through 360 degrees. Note that this is using the latest Diamondback debian packages. The latest Electric seems to have a bug wherein the arrow points straight down instead of horizontally.

Hi!
In the "displays" window of rviz, try to set the "keep" field of the odometry message to a value greater than 1. This value indicates how many past iterations (past arrows) keep in the display.
bye,
