error: can't open ricboard port. make sure that ricboard is connected

[helon1995]

Hi friends,
I have some trouble with my komodo robot.
When I input "roslaunch komodo2 komodo2.launch" in terminal, I get an error as below.
"[ERROR] : [komodo2_hw/ricboard_pub]: can't open ricboard port. make sure that ricboard is connected. shutting down..."
So I want to know what is ricboard and how to solve the problem ? Give me a hand please!
Thanks very much!

Hi helon9525,
Ricboard is the name of the microcontroller we are using inside the robot. It is connected to the PC via USB cable. If the PC can't find this connection, then trying to launch komodo2.launch will lead to this error.
Please provide more information:

1. Does the command you are trying to execute worked before?

2. What software version are you using? You should use this version:
   https://github.com/robotican/komodo_2.0/releases/tag/V1.0.1

3. Try to run
   ls /dev/komodo2/
   Do you see RICBOARD in the output list?

Hi elhayra,
Thanks for your reply, I will provide some information for this problem.

1. When I first launched komodo robot the day before yesterday, it worked successfully. The I executed rviz to get some visual information from sensors such as laser radar, sonars and camera. For a few minutes, I heard "ricboard disconnected, shutting down" and some error information occurred in terminal. I had to press ctrl + c and tried to launch robot again. Then the error occurred as I showed before.

2. When I run
   ls /dev/komodo2/
   There are only BMS, REALSENSE and ROBOTQ in the output list. I could not see RICBOARD.

So what should I do to solve the trouble? Hope to receive your reply! Thanks a lot!
