Manual fix to issue#287 for NXO.

***DO NOT EVER MERGE.***

Unlike https://github.com/start-jsk/rtmros_hironx/pull/290 for hironx, this didn't go well as far as I tested manually and saw the visual on RViz; the issue https://github.com/start-jsk/rtmros_hironx/issues/287 still seems to be happening. I just open this PReq to share what didn't work out.
