That would only be if the arm were sticking straight up in the air. Most likely, the arm will be at an angle when deployed, reducing its height off the ground.

For example, at a 30 degree angle, the arm would only add 25" to the 38" height you mentioned. This team is probably within the rules.

Remember, the 72" limit is within the plane parallel to the floor, not the height. In any case, you're right that it's only a problem if your arm is straight out. I did some trig here that indicates that a widthless arm would be allowed to protrude up to 49.8 inches, minus rear bumpers, from the front of your robot. (Though that thread was speculative, my interpretation was upheld by the Q&A.) So, as long as they don't have their arm straight out while fully extended, they should be perfect.

The 49.8 inches is assuming that your arm has no width to it. The wider your arm is, the shorter it can extend without breaking the 72" x 72" box.

Well, firstly' the 49" is NOT taking bumpers in to account, and as lil lavery said, you have to take the width of the end of the arm into account.
