Our robots have had many "communication issues" stemming from random drop-outs to random reboots (all while using the default code), and at least 3 tournaments here in Texas had to go to using tethers because the wireless just could not be trusted - when teams play 8 rounds and have a combined connection time of less than a minute, there's something bad wrong.

I'm not here to blast the VEX system, I'm just here to say it's not the bastion of hope everyone is looking for.

As a counter point. I have been running VEX events since 2008 Houston VEX.
When the CORTEX system was first introduced in the college division in 2009 there were definitely bugs and errors.

However in the past 2011-2012 year. I have seen a significant step in quality and reliability in the VEX CORTEX robot and field system. I have helped field tech four events in Texas (Galveston, Houston, Austin Fall, Austin Spring) combined together that's roughly around 400 matches.

Although I'm going from memory, I have seen less than 10 bad matches out of 400 matches. The errors from these matches are typically not using the standard programming template or failure to sync keys.

This coming season, I will carefully document each communication failure to keep better documentation of the field issues experienced with VEX. However I can attest that the system is extremely reliable from years of experience.
