Description

Often when I spawn a hokuyo in the environment, its laser scan is not rendered, typically the first hokuyo in a given gazebo session. Latching the "~/sensor" message seems to fix it for me.

If we had a way to test gzclient, I would do the following:

  1. Load an empty world gazebo.
  2. Click insert model, select hokuyo, and place it somewhere on the ground plane.
  3. Verify that it draws its laser scan.
  4. Repeat several times from a fresh instance of gazebo.
