Publishing 2D arrays with ROS

[no_cap]

Is there a good way to publish a 2D array from V-REP to a ROS topic? I'm trying to publish position information for multiple objects in my scene all at once and would like to be able to publish them all in a single message per time step as opposed to publishing each one separately to different topics.

Thanks!

You can create your own message, or you can re-use one of the many standard messages, e.g. geometry_msgs/PoseArray or std_msgs/Float32MultiArray.
