Hi @Echo334 Could you explain what you are trying to do? For me it looks like you are trying to build and run the OP humanoid source code.

Echo334 commented 3 years ago

Hi @ROBOTIS-Will Yes, as you said,I'm trying to build and run the OP humanoid source code.But the robot didn't run the program, as I expected.All in all,I want to know what I should do to restore the robot to normal.

@Echo334 I'm sorry about the delayed reply. Could you specify the OP model you have? Is it OP3? Also, did you change/upgrade any component? When the USB camera is not properly connected to the PC, you may get /dev/video0 error. Thank you.

Echo334 commented 3 years ago

@ROBOTIS-Will Thank you for your reply. In fact, our robot model is OP2. We haven't changed or updated its components. There's no doubt in my mind that the problem is the USB camera is not properly connected to the PC. So what should we do to solve this problem?

ROBOTIS-Will commented 3 years ago

@Echo334 The error clearly shows that the USB camera is not detected by the system. Could you try below command and paste the result here?

$ ls /dev/video*

@ROBOTIS-Will I'm sorry about the delayed reply.In fact,when I connect again, I couldn't connect to Putty and Vnc suggested an error which is 'Failed to connect to sever'.

ROBOTIS-Will commented 3 years ago

Are you trying to upload the OP3 software on OP2? OP2 has its own ROS software and OP3 packages may not compatible with OP2. Please use OP2 packages as instructed in the eManual below. https://emanual.robotis.com/docs/en/platform/op2/ros_package/#robotis-op2-ros-packages

Since you are not using ROS, please disregard the above comment and let us know the result of the below command in your OP2 terminal window.

$ ls /dev/video*

Thank you.

Sorry, I can't do as you said, because I can't connect to the OP2 terminal window at the moment.From the current situation, I think the problem is that the USB camera is not properly detected by the system.Is there any possibility of camera damage?

ROBOTIS-Will commented 3 years ago

You can directly connect the monitor and input devices to OP2 instead of connecting via ssh on terminal. Camera or cable might have been damaged if you don't get anything from the aformentioned ls command.
