This is a picture of the chassis that Team Unlimited actually used in competition for the FIRST Vex Challenge for the 2006-2007 season. This is the original chassis, it changed a little after that picture was taken. If you want more information on how we made this gear shifter, you can find the information on our website at: http://eaglevex.syraweb.org/GearShifter.htm
There are gear shifter renders there at show the shifter in Maya 8, the text on that page will explain how we made this shifter, and how it works.

Team Unlimited would like to wish the best of luck to all FIRST teams for the coming competition season!
