Unfortunately, I don't have a picture of it. And sorry I didn't check this thread for a while. Without an actual picture, it may seem hard to believe, however, I do intend to show that I'm not making this up.
Firstly, some math:
Our arm extended from approximately the top back corner of the box to the front bottom the long direction, plus we have what some on our team called the 'sugar scoop' on the front, which is about 2.5 feet tall. When the arm is fully extended, this is straight up.
My math gives me a possibility of 13.4 feet from these dimensions:
60+sqrt(38^2 + 60^2)+30=161"
You can subtract from that a couple feet (probably less) because the tetra is held from the peak, and (somewhat less than) a foot because the pivot point is a few inches from the upper corner, and you still end up with a possibility of over 10'.
Now, from a visual perspective:
From the competitions we went to, we don't have any pictures of the arm all the way up either. This is because there was no reason to have it all the way up.
Here is a picture from later that night:

Notice the tables in the background. It was one of those tables that we used. Also, notice that on the right side of the picture, there are some grey pipes. Those are the edge of the center goal.
Here are some other pictures of the robot that show just how much of its power is unused:
Here is us stuffing a robot, as it holds three tetras over the center goal:

Notice that even from a perspective partially behind the robot, you can see that the arm is not fully tilted up.
Closest to all the way up that I have in a picture:

Unfortunately, there isn't too much in the background to measure against, but you can see one of the factors that helps how high the tetra can be: as the top piece gets closer to vertical, the bottom of the tetra gets closer to the top of the robot as it tilts.
On a final note, here is a picture of our robot with its old arm:

This one was made of fiberglass, and was telescoping. At the pacific northwest regional, the mechanism that made it telescope broke in one of the early rounds, but we didn't bother to fix it because the capability turned out to be useless. (The arm was too long for its strength, and was later replaced with aluminum.)
As for how tall it actually was, we didn't measure, but it was a regulation size tetra and center goal on top of what I assume is a pretty standard table height.
