what is total length for 2007 robot?

[Justin M.]

To be more specific, your active playing configuration must fit in a imaginary 72"x72" box, with no height restrictions. Keep in mind the playing configuration means from the outer most tip of one side, to the outer most tip of the other side. This means bumpers are included.

[Gary Dillard]

If your appendage is centered on the midplane of your robot here's a good way to see if you fit in the envelope:

The diagonal of the 72 x 72 box is 72/sin45 or 101.82 inches. If you back the robot up to the corner of the box and your robot is x inches wide, you will lose x/2 worth of the diagonal on that end (tan45 = 1). If your appendage is y inches wide at the tip, you will lose y/2 worth of the diagonal on the other end. So, your total length from the back of the robot to the tip of your appendage at maximum deployment can be no longer than 101.82 minus one half the sum of the widthes at each end.

This is as advantage for an octagonal shaped chassis like ours - we are 18.75 inches wide at the back which gives us an extra 4.625 inches available reach versus a full 28 inch wide chassis.
