smiguel is an unknown quantity at this point
Sometimes slow auto turns

We have been working on our autonomous sequences and have been having an issues on one of our turns. The robot goes through 5 turning sequences with gyro values. After the second turn, every time the robot needs to turn again it does so at half the speed. We check motor speed values and they are constant through out. Any one have any ideas why this might happen?

On the first turn, you're activating both sides of the drive train (one in reverse, one forward), and on the others, you're only activating one.

Anyway, there's almost no possibility of us helping you without you posting your code. We can't help you without you at the very least posting your code.

This seem to be the problem. We activated both and it seems to be working much better.

Sorry that I posted in this thread, I thought I was in another thread.

Re: Sometimes slow auto turns

Possibly a code issue? Do you have any errors in code when you boot up the FRC driver station to the robot?
