Hello everyone,

I am currently working on robopeak rplidar,

I used github to setup everything,now everything is running good .but when i launched view_rplidar.launch it launched everything including RVIZ As expected ,but RVIZ didn't show lidar data in its GUI.

When i checked " rostopic echo /scan " it was not publishing anything .

I asked samething on they asked to check ros is having the access of rplidar or not I checked that also by overwriting "sudo chmode a+rw /dev/ttyUSB0"

Yet problem is same .... Rplidar is not publishing/scan data What can be the other problems

I have configured tf also .

Disconnect the sensor type in a terminal dmesg and memorise the last lines. Connect the sensor and enter the dmesg command, look for the memorised lines and some lines later you can see something like /dec/acm... Or /dev/ttyU... the you need the permision for this device chmod or chown and you have to configure the device in the configs your prlaser node

Try running the following. On some systems, the lasers get mapped there instead.

$ sudo chmod 777 -R /dev/ttyACM0
