hello sir, i'm currently learning ROS and Moveit through tutorial series. however, when i came across roscontrol, i got two tutorials - links as - 1) http://gazebosim.org/tutorials/?tut=roscontrol and 2) https://github.com/ros-controls/ros_control/wiki/hardware_interface . ofcourse, i understood(with my little understanding) that first meant when i want to setup with gazebo and second with moveit(ros), but when i came across 'standard used by moveit as well as gazebo', i got confused. does both tutorials end up with same result(package structure)? if not, then, in what way do they differ? thanks.
