Hello,
Well, firstly, welcome to ROS!!
I believe the links below will help you fulfill your task:
http://gazebosim.org/wiki/Install/Gazebo_and_ROS
http://gazebosim.org/wiki/Tutorials/1.9/Overview_of_new_ROS_integration
(follow the tutorials)
http://wiki.ros.org/ros_control
Also, take a look at my implementation of a ROS driver to Nao (nao_dcm
<
https://github.com/costashatz/nao_dcm>), where I am using ros controllers
(and controller manager) alongside with Gazebo. If you need more
clarifications, feel free to send me an email.
Although, I didn't understand completely what you mean a plugin that
manipulates the actuators.
Best,
Konstantinos Chatzilygeroudis
