[aqnpuilb] Robot baseball batter

Create a robot that can hit baseballs pitched by a skilled pitcher.  Has this already been done?  Some ways to make it even more difficult:

1. Instead of just hitting home runs, hit specific targets.
2. Moving targets.
3. Taller pitcher's mound.
4. Closer pitcher's mound.
5. More textured ball.
6. Thinner bat.
7. Limit bat speed to how fast a human can swing.
