Hi Chris, How were you able to fix? Also our large motors making crunchy sounds while running, when compared to others teams robots that run very smooth. Is there a factory reset kind of a thing that we can do on them.? Also how to resolve the jerkiness when the robot starts from a stop.? >Thank you to all of the coaches that responded to this post. We were able to fix the drift. -- To UNSUBSCRIBE or CHANGE your settings, please visit https://listserv.jmu.edu/archives/vadcfll-l.html and select "Join or leave the list". -- VADCFLL administrative announcements are sent via VADCFLL-ANNOUNCEMENTS-L.
