Re: [FTC]: Losing Control During Competition

I presume since you are using The RigRunner that you are using PowerPole Connectors as your main battery connector. If you are still using the Tamiya and the control lost was short, then there in lies your issue. Also, make sure the Samantha is the first device fed off the RigRunner.

If you were to crack open your Samantha Module, you'd find USB port soldered onto the board. You've done well to stress relief the cable but the port is still a weak spot. I'm seeing Model 1 Samanthas starting to break.

Depending the age of the NXT and the use of it, there in lies another issue. Teams that are bringing their NXT up from FLL are likely to see their NXT wear out faster from sheer use. Also too much code the NXT can bog things down, cause lag, etc.

Also, if your NXT's Bluetooth was on, there could the biggest cause of your issue. I've had a team in the Final lose connection with the field cause their bluetooth on the NXT was pinged by someone's phone looking for a Bluetooth connection.

When you got to your NXT after the Match, was the brick locked up? If so there could be the root of the problem. If it wasn't locked up was code still running or had your Teleop program exited? If that has happened and you are using Labview, then you need to look at the laptop you are using to program and upload code. If LabView for both FTC and FRC are on it, then there is another possible cause of the teleop exit. The 2012 and 2013/14 LabView may program the same way but don't necessarily upload the same.

I'm not saying any of the above are the cause but they could be contributing factors. If you have any further questions, feel free to shoot me a message.
