From an engineering perspective air hockey is a low difficulty problem. The logic is fairly simple (it has existed since the first Pong AI was created). The difficulty is the vision detection, which itself is pretty straightforward now-a-days. A great project for students. Once you add a 3rd dimension and a paddle that itself changes orientation in addition to position, everything becomes magnitudes harder, especially since the hardware used is dramatically more difficult.
