Hi every one, I'm trying to have my model move through JointPositionController commands in Gazebo, but it won't. I'm using Kinetic/Gazebo7. The model (derived from ABB IRB2600 with dynamic items for Gazebo) seems to be loaded correctly (Gazebo/Rviz), I'm using rqt_gui to publish command topic, yet the model stands still, no movement. I guess I missed something in controllers' configuration, but I'm quite a beginner and I didn't find any problem yet. Would you please help me to detect what's wrong / missing ? Thans in advance...
