AJ_M:
Can I make like an AD-HOC network and have the IP Camera connect to that?
Yes. In this instance, you are just putting the wireless router on the robot instead of having it somewhere stationary. If you go that route, why not just have the router sitting right next to you? It would basically act as the receiver to the IP Camera.
Going further, what about an IP camera that supports adhoc mode and just using the wireless on the computer?
