Hello there, I have followed the Chapter 3 on ROS Hydro, when I roslaunch seven_dof_arm_gazebo seven_dof_arm_world.launch and roslaunch seven_dof_arm_gazebo seven_dof_arm_gazebo_control.launch and get below error. Actually, the first launch had throwed the pid gain error.
another question is: I found the rrbot control.yaml is using the effort_controllers/JointPositionController and your seven_dof_arm use position_controllers/JointPositionController what is the difference and which is better?
Any help with this would be appreciated. Thanks in advance!
