Barracuda WiFi Robot Controller

Hi,

This is my first attempt to build a robot. I am trying to build a Wi Fi Spy Bot robot as shown at this website: http://www.robotics-redefined.com/index.php?main_page=page&id=4

I want to use the "Wild Thumper" 6WD all terrain robot chassis that is sold by DAGU. My question is where can I find a Barracuda WiFi Robot Controller ? I have not seen one used anywhere I have looked on this site. Is there something that would be better or more cost effective. Would be nice if I could order the controller when I buy the chassis.

Any help would really be appreciated.

 

Thanks

David G
