Robot losing and regaining drive power

[PSHRobotics]

I guess I'll start with the post right after mine. Thanks to everyone again for your help!
When the robot is on blocks/lifted up we don't see any of problems at all. Every time we were about to leave the pits we would check movement forward, backwards, right and left. There was not a single time when the movement in the wrong direction.

We have 6 wheels. There are two lager wheels and the are in the middle of each side. These are the only wheels being driven by the motors. I do remember we checked the wheels by hand a couple of times, but I will make sure we check again Wednesday.

I will make sure we check the drive train and make sure something hasn't come loose. We haven't really worked much on the drive train after the first two or three weeks of the build season. It does seem possible, but the reason we didn't think it was something like a drive chain was because we didn't need to wiggle the robot to get it to move. Simply holding the joystick forward would eventually lead to the robot moving again.
Also, I'm not sure if that makes a difference for the turning problems but we are using arcade drive not tank.
Thanks for the information Al, if it keeps happening I'll make sure to watch the time more closely just to make sure I'm not dramatically over/under estimating.

So would that mean that a mechanical or electrical problem would be causing the jags to stall and its not specifically the jags? And we are not using CAN but I agree with your analysis that it would most likely not make a difference.
Would a circuitry problem with one jag cause there to be problems for the other jag? If there is some movement from a specific side when the robot is not "responding" it is only at the very moment the joystick is pushed forward. Most of the "driveless state" the robot is stationary and it does not appear to be attempting to move (not fully sure).

How can we check if the problem is a digitical sidecard power short? And if it is for directional data, would we still see the problems moving forward?
I do believe that forward is the jags in reverse, so it is possible what you're saying is absolutely correct. So if the jag is having this problem moving in the reverse direction, how would we know that it is having a fault? I know it does not do this without load, which from the previous posts seems to show that it isn't a problem with the/a jag going in a specific direction.

We updated our driver station software at competition. We had been running fine with the old one, and one of our allies did have a problem with their driverstation so I have seen it for people before. But there was an error given on the driver station window whenever their robot froze. We didn't see anything like that.

That sounds fantastic Kevin, once we get our robot ready to go I'll be sure to come find you!

Thanks again everyone! I'll let you know after Nationals if we figure it out.
