2.2.5 The TOWERS

The TARGET is attached to the top of the POST. The TARGET is the “finish line” that indicates the MINIBOT has reached the top of the POST. The TARGET consists of a pair of 12-inch diameter polycarbonate disks, spaced approximately 2 inches apart. The bottom of the lower disk (i.e. the portion of the TARGET contacted by the climbing MINIBOT) is approximately 122 inches above the floor. As the MINIBOT climbs the POST and contacts the lower disk of the TARGET, the disk translates upwards approximately 1/4 inch as the sensors internal to the TARGET register the contact. A minimum contact force of approximately 2-4 Newtons, depending on contact location, is required to ensure the contact sensors in the TARGET trip reliably. The contact sensors and associated electronics are located between the upper and lower disks of the TARGET.

I am sorry if this isn't enough, as it is simply an interpretation. However, I take this to mean that since you must "trip" the target reliably, and move it up 1/4", as long as you are able to do as such, your finish light should then turn on.
