Subject: [ros-users] [Discourse.ros.org] [ROS-Industrial] Integration of 6-axis manipulator and 2-axis positioner (external axes)


@gavanderhoorn: both manipulator and positioner are integrated with a DX200 controller. Here is Eric Marcil's answer to a similar question:

So I think our system is in deed setup as a multi-group system. It has actually not been delivered yet but we should have it up and running some time in March. So far, I have been running `moveit_planning_execution.launch sim:=true` to simulate the robot and that is when I've run into the above errors. So the question would also be whether the industrial robot simulator has multi-group capabilities since simulating the robot prior to execution is also required.

I have not configured the `motoman_driver` but will look into that next.
