[Solved] Error happens when launch ROSBot 2.0 pro

Hi,

I am trying to launch my rosbot 2.o pro. I have checked that the ip address I am using is correct. I got this error. What should I do? Thanks!

Hi Kong,

You are trying to connect to serial port /dev/ttyS1 witch is default for ROSbot 2.0 not a pro version. My guess is you forgot to specify rosbot_pro argument when launching:
roslaunch rosbot_ekf all.launch rosbot_pro:=true
