Sounds like you are interested in web control of the bot with a video feed from the bot. Below is some recent discussion that has example code serving .js files from an SD drive on an arduino ethernet board. The bottom link has some info on making a simple bot using an inexpensive router that can support an IP cam. bottom is some simple web page control code.
//zoomkat 4-1-12
//simple button GET for servo and pin 5
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use the \ slash to escape the " in the html, or use ' instead of "
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields
