Team 5720 Driving Question
 

Right now we are using the rhino treads from Andymark.com and the driving is a little weird. By that I mean that as you are going straight, it sometimes jumps/ slowly curves to the right when the joystick is completely straight. Like if you push down fully, it will go straight and then after about 15 feet or so it does a little jump to the right and then heads straight again.

This problem is also prevalent in our autonomous code. We use Labview to program. We have it set up like the first page in the link below, except that we are using the tank drive VI instead of the arcade drive VI, and when it is set to only go completely straight for more than 3 seconds, it jumps a little to the right like when we drive it. The only thing I can think of that could be wrong with this part at least is power distribution to the motors. I used Labview last year and know enough for basic programming but I don't know that logistics of everything and I don't know how I would fix that.

When we run the robot we also get Error 44061-saying that a loop containing RobotDrive.vi isn't running fast enough, or something like that.

If your AUTO and manual drive have the same issue it is most likely an electrical or mechanical problem.
Issues could be one gearbox is not lubricated well, motors may be mounted incorrect, wires are loose. Give it a good step by step troubleshoot.

The weird thing is that we have done that a lot. We noticed that the back of the treads were rubbing on the frame and heating up so our build team put washers in to space it out and that fixed the heating issue. Another time we replaced a baring in one of the pulley sets since it was making a creaking noise when we drove it and we fixed that. We are also fairly certain that the tracks probably aren't getting caught on anything and lacking. One thing I can think of is that our back right small black belt that helps rotate the tracks is tighter than the left one but they both came with the tracks themselves.

Are you using talons for your motor controllers and without them wired via CAN? We ran into this issue last year. Calibrating them fixed it.

We are using Talon SRs and what do you mean "without them wired via CAN"?
