can you give a little more detail about what you are doing with the robot? – Slimu Feb 21 '14 at 14:39

if you pressed `@` then it must be **`VK_AT`** – Suzon Feb 21 '14 at 14:41

On my keyboard, the @ key requires combining the Shift and 2 keys; others may vary. The test image below was produced by adding the following to this example.
Addendum: As noted in comments by @neat159, the host OS keyboard control panel setting must match the intended keyboard layout being tested.
r.keyPress(KeyEvent.VK_SHIFT);
r.keyPress(KeyEvent.VK_2);
r.keyRelease(KeyEvent.VK_2);
r.keyRelease(KeyEvent.VK_SHIFT);

1You may have to change something in the host OS's keyboard control panel; mine's set to U.S. for both Mac OS X and Ubuntu. Interestingly, mine accepts a `VK_ALT` modifier, but silently ignores `VK_ALT_GRAPH`. – trashgod Feb 21 '14 at 18:23
