Hi guys, I'm a beginner of robotino development, and I develop some application on robotino3 which have to use the data of SICK(laser scanner, see the fig below, the yellow one)

I tried to use REST-API to get the data(/data/scan0), but nothing came out.
(The image I used is " )
and I also deployied ROS melodic on the OS, and launched the robotino_node and still did't get it.(topic: /scan, include laserrangefinder.h)
Does someone know what's wrong with it? Is there really a SICK Laser Server running in daemon? Or what else things should I do?
Thank you.
