Revision history [back]

The "base.launch" file previously started the EKF filter (which would publish /odom->/base_link transfrom). That launch file has been merged into minimal.launch (as that transform is needed very often, and we were trying to reduce the number of launch files). It looks like a number of launch files in the /apps directory didn't get updated, I'll get those patches pushed into mercurial tomorrow.

The lack of movement, is probably due to a different change: we've stopped mapping "cmd_vel" into "turtlebot_node/cmd_vel" as it's really the wrong thing to do. So, it is likely that turtlebot_node/cmd_vel is still running around somewhere (although I can't seem to find it). In the meantime, you should be able make this work with a relay:

rosrun topic_tools relay turtlebot_node/cmd_vel cmd_vel
