This turn does not involve sensors.  It's just a plain point turn.

I wish I knew what causes this. We see it occasionally. Something lose
wires. Sometimes changes in battery levels. Do check to make sure that if
you are using sensors that they are working reliably.

Our team has a part of its program where the robot is supposed to turn some
nominal amount (around 30 degrees) and for some reason every 5th run or so,
it spins about 120  degrees.  They have put a reset motor block, a break
block and even a 1 sec wait block in front of the errant turn in order to
stop the issue, but nothing they have done works.  They've even tried
deleting the block and putting another one in.  They thought it was the
gearing on the wheels coming loose which also causes it to act up, but on
the 6-9th run it works fine and then at run 10 it does it again.  Well not
quite that predictable, but you get my point.  Has anyone else had this
problem and is there a way to fix it, or should the team just be resigned to
blow a round at the tournament?  Thanks for all the help - this is our first
year!
