Multiple robots with multiple robot_descriptions and ros controllers?
Does anyone have a basic example of multiple robots each with a unique robot description and set of ros_control controllers, being loaded from a ros launch file and running alongside each other?
I've run into some problems trying to accomplish that described partially here
http://answers.ros.org/question/198929/running-controller_manager-spawner-with-mybotrobot_description/
, it seems like I can't launch a controller for the second robot because robot_description
lies within a namespace- perhaps I'm forgetting to pass/remap a parameter for robot_description
? (though it isn't clear how the gazebo would know I've done that on the controller loading end if it is on the other side of a service call)

Running multiple robots in ROS is a known issue. Try googling "ros multimaster". I don't have personal experience with multiple robots + ROS.

@Lucas Did you solve the problem? I am launching Gazebo Shadow robot arm-hand first and then rrbot (from here http://gazebosim.org/tutorials/?tut=ros_control). And I can not launch these robots in one launch file. When I lunch them separately, it seems that /robot_description is overwritten by the second robot.

@Lucas Did you manage to get an example of multiple robots each with a unique robot description and set of ros_control controllers? I'm also stuck at loading the controllers.
