Control Arduino Robot from web

Hey,

I'm trying connect Arduino robot via web (wifi), to be able to control my robot from anyplace. I've try connect my raspPI to ardunino, and raspPI are connected to a socket them I able to control from web interface in any device include mobile. Is there a possible solution? Or it's better buy a wifi modulo like CC3000?

Anyone I've try control arduino with raspPi?

You may want to check the ESP8266 chip as a wireless web server as this chip is becoming popular and is inexpensive.
