A friend and I are planning to build a remote controlled vehicle, probably 4 wheeled. We want to be able to operate over the distance of about a block, which isn't incredibly far. The tricky part is that we need it to be able to send us back audio and video, along with being able to receive control inputs from such a long distance. Forgetting the complications of designing the hardware to process all of this for the moment, what is the most reliable way to move all this data around? Could a RF setup handle all of it?
