moveit Action client not connected

Hello,

I need help with MoveIt setup for a custom robot. I am using ROS Indigo, Ubuntu 14.04 with latest MoveIt.

All robot packages with MoveIt configured are here: https://github.com/byeongkyu/safe_arm
The robot is described here: http://www.slideshare.net/ahnbk/oroca-seminar

It can be started by running these files in separate terminals:
roslaunch safearmbringup bringup.launch
roslauch safearmbringup bringup_moveit.launch

The path planning works, however execution doesn't. I get the following error when starting the simulator:

Also, I get warnings:

I have these packages installed:

ros-indigo-gazebo-ros-pkgs,
ros-indigo-gazebo-ros-control,
ros-indigo-moveit-*,
ros-indigo-ros-control,
ros-indigo-ros-controllers,
ros-indigo-joint-state-controller,
ros-indigo-effort-controllers,
ros-indigo-position-controllers,
ros-indigo-joint-trajectory-controller.

Is there something missing? I have spent a lot of time tweaking the configuration files, but no luck... Any help would be much appreciated.

Solved the problem by installing Gazebo4. Initially I have been testing with Gazebo2, but seems like ros-control is not fully compatible with it...

Hello Sorry, but could you solve your problem?.. I have the same problem and I don't have idea how to solve it

Hi! Yes, I have solved it by upgrading from Gazebo2 to Gazebo4. If you set up ROS Control with your robot model properly it should work. Check out this project: https://github.com/byeongkyu/safe_arm . It is a working example of MoveIt + ROS Control.

hello, I test your safe_arm package, but have wrong output:

MoveitSimpleControllerManager: Action client not connected: safe_arm/l_arm_joint_controller/follow_joint_trajectory

I use gazebo2 in indigo, I need upgrade my gazebo?

Did you ever fix this issue? MoveitSimpleControllerManager: Action client not connected: safe_arm/l_arm_joint_controller/follow_joint_trajectory
