robot controlled through web using gps ?

Hi,
I am making a fire fighting robot that will put off fire with water using a dc water pump.
At first the robot will be remote controlled so there is no need of any sensor.I will be using standard 6 channel transmitter and reciever to control it.
For autonomous version i will use a fire detecting sensor.
For controlling it through Pc remotely i will mount a wireless webcam on the robot.

Now what i want to know is How can i control it through web.
I am quite familiar with C language and arduino.

Problem:
I dont know how/where to start with web controlled robot using arduino.
What hardware should be used ? Is netduino meant for this kind of application ?

you can use an Wifi shield with arduino that can talk to a master web server.

Look in that way.

The arduino+wifi will get and sends commands to drive the robot.

Below is some simple testing using an ethernet shield and wireless router.

Ethernet shield is just what i needed. Is there any tutorial on how to use ethernet shield ? how to connect client ,server and components ? any example codes ?
