Hi there, have you solved this problems? could you please share your experience, cos I encountered a similar problem,when I used care-o-bot (cob)in simulation. I deliberately set the goal under a table via rviz, then the cob robot will navigating to the goal, until it realised the goal is blocked, COB then feedback an error say:

HI Chengxiang,

have you check the feekback from rviz(from the terminal which you run rosrun rviz rviz ), if a 2D NAV GOAL was set up properly, the feedback will look like: if you got this feedback, but you robot still did not move, then you can try to use teleop_keyboard.launch to test whether the robot move or not.

if I remembered well, the command for launch teleop pr2 is: roslaunch pr2_teleop teleop_keyboard.launch

In summary, there are various reasons can result in your robot fail to move, you should do a proper test, then modify your question with more details. also before you do any test, after you launched the simulation , you can use this command to view whether your robot received any commands telling it move rostopic echo -c /base_controller/command

hope this can give you some helps.

rxgraph simply uses graphviz. The viewer that rxgraph uses is called xdot, which sits on top of of graphviz.
