robot.get_current_state() does not publish current state when using moveit_commander.RobotCommander()

[Peng Chang]

Hello all,

I'm using Sawyer robot with moveIt planner. I used the "robot = moveit_commander.RobotCommander()" and "print robot.get_current_state()". The output is showing below (the joint states are 0s or empty):

============ Printing robot state

By the way, by referring to "https://groups.google.com/forum/#!topic/moveit-users/jKV9QuHeFXU", I tried to use "roslaunch sawyer_moveit_config sawyer_moveit.launch electric_gripper:=true joint_states:=/robot/joint_states" to remap the /robot/joint_states. It could not work either. Can you help me with that? Thank you.

Can anybody help?

In my case, when i use joint_states:=/robot/joint_states to remap it's work.
