baxter_assistive_robot_ros's Issues

Can not get robot status in robotraconteur

I initialize the left_arm object in two scripts and try to get the joint angle of left arm. In baxter_measure_zero_point/baxter_pnp.py file. The left_arm.get_current_joint_values() works good.
But in baxter_rr_bridge/scripts/jointcontroller.py file, the left_arm.get_current_joint_values() function can not give the expected output.
The actual output is
[ERROR] [1561401413.923835617]: Failed to fetch current robot state []

Setup fail in ubuntu 16.04(ros kinetic)

When run the launch file
roslaunch baxter_rr_bridge launch_baxter.launch, the error happens in jointController_host.

  File "/home/ruijie/baxter_ws/src/baxter_rr_bridge/scripts/jointcontroller_host.py", line 1328, in <module>
    main(sys.argv[1:3])
  File "/home/ruijie/baxter_ws/src/baxter_rr_bridge/scripts/jointcontroller_host.py", line 1291, in main
    baxter_obj = Baxter_impl()

    self.both_arms = moveit_commander.MoveGroupCommander('both_arms')

    self._g = _moveit_move_group_interface.MoveGroupInterface(name, robot_description, ns)
RuntimeError: Unable to connect to move_group action server 'move_group' within allotted time (5s)

And error in peripherals_host
