Need some help using ZigBee with Cyclone II

Thank you for your response.

I now know for certain what I am going to use, therefore answer your questions better :

XBee 2mW Wire Antenna - Series 2 ( ZB )

Unfortunately, I have no experience whatsoever with Linux, nor with NIOS.

The only tools I have are the robot, Quartus, Cyclone II kit , and the Xbee aforementioned. The operating system I'm using is Windows 7.

Since Battleship is a game played by two players, I'll probably be using two Cyclone II kits,connected to two monitors(each one will show two boards/grids: the player's and the opponent's).

Now, the part where zigbee comes in, is after announcing a target square in the opponent's grid which is to be shot at , the robot goes to the specified coordinate and then the ZigBee "tells" whether or not the shot has hit one of the opponent's ships. In Quartus, I want to create a certain controller, which will be handling the ZigBee . It will get 4 inputs (Left,Right,Up,Down - which will tell the robot how and where to move) and an output (zigbee) which will go to a certain RAM I made in Quartus.

Is it doable ? How am I implementing ZigBee in Quartus?

Thank you.
