A while ago, I made ReCoRVVA. I was one third of the team that built it, the other two members being Finnian Anderson and Angus Ledesma.
The ReCoRVVA stands for the Remote Control Robot Vehicle for Various Applications. It’s a robot that can be controlled from anywhere in the world from a variety of mediums, Wii remote, xbox controller, or web interface. It has a live video feed from a camera with full pan/tilt control, and auto-detection of obstacles; if the signal is lost between the ReCoRVVA and the controller, it won’t crash (in a physical sense, that is)!
