Does anyone know why the care-o-bot will sit in place and rotate about the z axis with some move commands. For example:

self.sss.move("base","order");

From a startup state, the above command in a python script will cause the bot to spin in place. I'm running ubuntu 10.4 with electric.

What kind of navigation are you using? I assume you are using "roslaunch cob_2dnav 2dnav.launch", which is the ROS navigation. Sounds like the robot in not properly localized. Please check the localization in rviz.

Thanks fmw. Pardon the newbie question... but is it required that I run care-o-bot in rviz? In working through the tutorials, I was under the impression that I could apply navigation goals (by python script) in gazebo. What exactly does rviz add that I cannot do in gazebo? I'd appreciate any comments you have - I'm new at this.

Oh - and yes, I'm using "roslaunch cob2dnav 2dnav.launch"

Gazebo is a simulator (generates data) and rviz is a visualization (consumes/visualizes data).
