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 5^th 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 6-9^th 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!
