I am making a Wi-Fi robot by modifying the controls of an RC car with Micro-controller to steer, IP camera, both of these connected to a Link-sys router that streams the video to my desktop where a C# based application shows video and arrows to steer the vehicle. Plus a GPS to locate the vehicle. It will have a range <= 500m.

i want to ask what feature i am missing that can make this project innovative? In other words what can be a new addition or modification to make this a wow:-O project.

Well you already have GPS and a camera, geo-link the images?

Search for data (images, speeds, distance etc) by location?
