Yes, I'm having precisely the same problem. I have a table where the mat has been left alone for many weeks now and there are still noticeable waves near the middle. I don't recall having this problem in the past so perhaps there was a manufacturing issue with the mats this year. The field setup instructions suggest using a hair dryer to help smooth out waves but I think those are waves due to storage, not manufacture. It is probably reasonable to assume the tournament mats will be just as wavy so it may be better to simply deal with it in your robot design. For this reason, I haven't tried to fix the mats. --- Stuart Roll Sterling, VA 2006 - Banano Splits #1494 2007 - Solar Pickles #6567 2008 - <TBD> #3502 2008 - The High 80s #4197 -----Original Message----- From: First Lego League Discussion [mailto:[log in to unmask]] On Behalf Of Michael Blanpied Sent: Thursday, October 09, 2008 11:29 AM To: [log in to unmask] Subject: [VADCFLL-L] Wavey mat Does anyone else have an issue with wave in the mat this year? Our mat won't lie completely flat on the table. The outer edge does, all the way around, but the middle has waves running north-south. It's as if the middle perhaps 50% of the area has been slightly stretched east-west and is slightly too big for its surroundings. I'm not sure if the waves are big enough to be affecting the robot's travel, but they're certainly prominent. I'd be curious to know if anyone else has this problem, and to know of any workable solutions.
