Re: Tower Rung Height

From the manual:
Quote:
Illustrations included in this section are for a general visual understanding of the FIRST STRONGHOLD ARENA, and dimensions included in the manual are nominal. Please refer to the official drawings for exact dimensions, tolerances, and construction details.
Obvious disclaimer, so take what's below from the manual with a greater or lesser degree of skepticism:

Quote:
The BATTER is a series of seven (7) ramps with two (2) dividers that create the base of the TOWER. Ramps are 6-8 deg. inclines. The ramps directly in front of the low GOALS are 2 ft. wide and 4 ft. deep.
Quote:
A RUNG is a bar mounted on a TOWER face that is 1 ft. 9 in. wide and constructed of 1-1/2” Steel DOM Tubing. Each TOWER has three (3) RUNGS, one on each face of the TOWER, designed to support SCALING robots. The top of the rung is 6 ft. 4in. from the FIELD carpet. The RUNGS protrude 5-1/4 in. from the face of the TOWER.
So, the manual states that the top of the ring is 76" above the carpet, and the top of the batter is higher than the carpet. Used as a logical check, it would seem that your calculations may be off a little. Also, it's important to note exactly where you are measuring to - the top, middle, or bottom of the rung.
