One of the teams contacted me with the following question:
"we wish to ask whether the route involves the presence of the tunnel, and if so the height of the latter."
I confirm that the use of the tunnel is possible and that the clearance (height) is 30 cm.
We also have received more parts for our track, this means that we might have more than one intersection (track X part) and that it might be longer than last year's track. See example attached as used at the Freescale Technology Forum 2012 in San Antonio where the University of Iasi won the competition.
