Revision history [back]

I'm having this problem too. I'm running diamondback. I can produce it with pretty recently checked-out pr2 stacks with the following

1. roslaunch pr2_gazebo pr2_empty_world.launch
2. roslaunch pr2_3dnav right_arm_navigation.launch
3. roscd pr2_navigation_tutorials; ./bin/move_arm_joint_goal

This hangs on line 10: move_arm.waitForServer();

roswtf tells me that all the move_right_arm subscriptions are unconnected. rostopic echo move_right_arm/* doesn't give me any messages either.

Can someone confirm this? I followed the relevant tutorials to the letter. I would very much appreciate any debugging suggestions.

Thanks, Tom
