The team & robot did very well
5 wins - 3 losses
Finished qualification matches 31^st out of 78 teams
We were not selected for a play-off alliance
DEWBOT VI played phenonimal defense, virtually shutting down scoring 1-on-2 during two matches
DEWBOT VI also scored very well in the near field

The drive team brought their Mojo
Siri coached 6 of the 8 matches for 4 wins and 2 losses. Great job!
The crazy wheel problem did not occur. Replacing steering Jaguars with Victors seems to have done the trick.
No fatal field failures. We played every scheduled match; through the match.

Communications - we had a communications problem between the Classmate and robot when tethered. No significant field failures. Most times, tethering through the router worked. Most times, tethering directly from the Classmate did not. We know we have a problem with the ethernet port on the Classmate, but this problem appears different.
Our possessor eats balls. It will not eat the team's practice balls, so there appears to be a significant difference between the two. We will correct this.
Possessor actuation failed. We destroyed two cylinders on the left side. Issue is poor alignment. We'll fix.
Possessor grip became less grippy. Need to explore this & resolve.
The mirror sagged. We removed (to avoid penalty). Need to fix.
Autonomous kicking often failed. When it worked, it was too late & missed the goal. We need to make kicking reliable and set angles empirically (calculated angles are a starting point, but the assumption for calculated angles is that the robot kicks at the original ball position. this is not the case. If we know speed & delay, we can refine the model)
The robot appeared to kick by itself in teleop. Kicking was mis-timed and ineffective. This may be a control issue, but more likely a user interface problem.
The user interface is complex and not understood by the drive team (esp. the driver).
The battery box broke (again). The field fix is quite effective.
