Very nice and easy to understand.
Now if only this video existed when I was learning to fly RC planes (it showed the basics of remotes and receivers in 8 minutes for what took me a month's worth of flying to learn).
Although, I always thought of robots as completely (or partly) autonomous systems. The "robot" in the video seemed more like a RC car than a robot to me. Of course, it is a simple, first-time project for beginners: if/when they expand it and make it do more complex things, it could be considered more "robotic".
