[ros-users] Gazebo real time controller

[Stuart Glaser]

Hi Andreas,

The ill-named controller_manager.launch does not actually launch the
controller manager.  Instead, it launches other nodes that work with
the controller manager (publishing diagnostics and tf, I believe).
The controller manager is launched inside the Gazebo process as a
Gazebo plugin.

At Willow, we either launch the controller manager inside Gazebo or in
the process controlling a PR2 (pr2_etherCAT).  The controllers operate
on joint states and commands, which are provided by the robot or by
Gazebo.  Launching the controller manager by itself means that the
controllers have nothing to operate on, which doesn't make a great
deal of sense.

How are you trying to use only RViz as an environment?  In your
planned setup, where can you read joint positions from and where can
you send joint efforts?
