Robot heart attack

What does "dual-lighting" mean?

[TK3950]

I knew I'd have more information to put in, but I couldn't think of it at the time.
First off, the dual-lighting simple means the Motor controllers light green and red at the same time, so it looks a bit orange.

Anyway, our signal light is currently not operational, but that's an unrelated issue. The light on the digital sidecar seems fine, though. I don't think it indicated any issue, but I could be wrong, I just don't remember.
The driver station indicates communication and code as normal, and we were able to re-deploy code onto the robot, but it moving the joysticks didn't control it.
The issue is persistent.
We did not test the solenoids individually, so I cannot say they caused any change in signal.

The camera itself remained operational, there was no issue retrieving images from it. Only the ring of LED lights was disabled.

Any more questions or ideas?

(Thank you all for replying)

Were there any messages being reported on the Diagnostics tab of the driver station?

[TK3950]

Quite a few. I don't remember them off of the top of my head, and they weren't very clear error messages. One of them seemed to be about the joysticks, but I can't confirm that they are the issue just yet. Our testing will resume on Tuesday, and I will update if we get any further developments. I will also try to post the diagnostics from the Driver Station.

If you want help figuring out what the problem is, there's something simple you can do to make that help more forthcoming: tell us what the system is telling you. You're going to have to give plenty of detail about what's happening in order for people to be able to interpret the situtation and give helpful advice about what to do next.

Are the yellow LEDs on the motor speed controllers steady, or blinking? Blinking indicates they're not receiving a PWM control signal; steady means they're being command to neutral (stop). Blinking could be caused by many things, with the error messages and status lights able to narrow down the possible causes. Steady could indicate a problem with the joystick or the robot code.

Some information I can answer, however. The motor controller lights are blinking; they do not give a solid light.

Last year, week 5 of build season we had a similar problem happened to us. When the robot was enabled the cRIO wouldn't respond to inputs or print out data. We removed the cRIO and tried another one but had the same problem. Next we checked the digital sidecar. We went one by one removing the PWM cables to see if there was any small piece of metal shorting out the board. We eventually found the shaving and once it was removed the robot once again functioned properly.
