Autonomous did not work at official field but ok at practice field

[Fausto Vazquez]

Hi All.

I wonder if you have faced a similar situation, when we played the Phoenix regional we found that the autonomous sequence was not run at the official field and after ending the 15 sec, we could control the shooter perfectly.

We tried to find any miscommunication or bug on the software , also we confirmed that robot performs the autonomous sequence perfect at the practice field but it did not work at the official field.

Due to the short time and to avoid generate more issues in the robot performance we played only with teleoperated and we did not use Autonomous, obviously this cause that our performance on the finals were not the best and we lost at the first round.

If you have any suggestion of what could happened will be highly appreciated.

Thanks.

There's not enough detail here to tell exactly what might have happened.

• What programming language are you guys using?
• Did this happen on every match?
• Did an FTA(A) or field guy come over and tell you if anything was up with FMS's communications?

-We use Lab View

- This happend on all the match

- we Approach him and we reviewed all the setup , also we got support from other teams and we can not found the issue.

Did you talk to the FTA and/or CSA at the event? They are the people most likely to be able to help.

Whenever there's an issue programmatically that you are unsure of, it's always a good course of action to stand in the question box and request politely to speak with an FTA/FTAA.

Just to double check:
Have you attempted to run the "practice mode" on the driver station while on the practice field?


More questions:

Do you reinitialize variables during the start of teleop?
Do you use any while loops?

[DominickC]

Instead of going through vague troubleshooting questions, it might be a good idea to post your code.

I will ask a copy and load it.

When you test your code on the practice field did you just run the autonomous feature of the drive station or did you try practice mode? I would suggest running in practice mode as it simulates the various state changes out on the real fields.

He already answered that.

- Yes, we reinitiated variables during start of teleop.

- no, we did not use while loops, we used flat sequence

Field logs may also prove to be valuable in the troubleshooting process.

This happened to us only once on practice day at Waterloo, however I could not see clearly if we were having a jam or not.

I'd recommend looking through the Driver Station log files and check to see how the connection was looking like during the autonomous period in the matches. I've also found that the FTA is more than willing to pay special attention to your robot if you guys are having problems and check for any anomalies.

Not sure how your DriverStation is set up, but ours has SmartDashboard and it displays a Scheduler, which allows us to see if a command is running or not. You guys could try that if possible to check if the robot is actually running your specific autonomous commands.

Here is the code of the autonomous VI
Thanks guys!

Our robot (team 701) had the same problems at the Sacramento regional.
We discovered that because we had the camera set up in autonomous,which was not needed anyway, and it was using too much band width on the field system.When we disabled it, autonomous worked perfectly.
