I am also following the book"Mastering ROS for Robotics Programming"and found this problem too.To resolving it You should copy codes about node "joint_state_publisher" from demo.launch to anyone of launch files of example codes with moveit+gazebo.(I pasted it to "seven_dof_bringup_moveit.launch". ) The codes: |
