panda arm tutorial does not move in c++ motion_planning_api_tutorial

[hankyang94]

I am following the motion_planning_api_tutorial, my system is ROS kinetic and Ubuntu 16.04.
There are two issues with this tutorial, which I am surprised that I could not find any similar issues and solutions to it.

1: console outputs error:
[ INFO] [1530492597.516038871]: Failed to call service get_planning_scene, have you launched move_group? at /tmp/binarydeb/ros-kinetic-moveit-ros-planning-0.9.12/planning_scene_monitor/src/planning_scene_monitor.cpp:485
I have seen similar posts about this issue, but there seems to be no solution yet. And some people say this should just be a warning instead of an error. Is this true?

2: the panda arm does not move even though solution is found.
The console outputs:
[ERROR] [1530492689.634402542]: Found empty JointState message [ INFO] [1530492689.634574456]: The timeout for planning must be positive (0.000000 specified). Assuming one second instead. [ WARN] [1530492689.634755603]: It looks like the planning volume was not specified.

But I cannot see the arm move at all during the process.

BTW, i did no change to the original code, both the moveit_tutorials and panda_config folders were directly git cloned to my local.

Could you help me identify what is wrong?

Change the Trajectory Topic in rviz (Displays > Trajectory > Trajectory Topic) to /move_group/display_planned_path

[keep9oing]

same but change topic in rviz is not help

[pranavb104]

I have the same issue...changing trajectory topic does not work....

[HDallali]

I have the same issue and the trajectory topic is already set to /move_group/display_planned_path

I believe this may fix the isue: #273
