I've just got S.L.A.M.dunk and I'm testing it. I always get all topic which I need- pose, points cloud etc. But I don't received any messages from /ultrasound topic.
I run sudo diagnostic and I get:
" 25-ultrasound ok [ultrasound] Ultrasound Result: KO Distances: "1.100 0.282 0.282 ""
So how I can enable this /ultrasound topic ?
Thanks for your help!
