[Robotgroup] Drive a Droid proposal... How to detect the "fence"?

[Gray Mack]

I like the idea of the wire based dog fence. Since it is RF sensors could be completely hidden, the question is of course how well it works. It needs to sense accurately about 10-12 inches from the fence. Upon detection, the easiest thing to do is make it go really slowly. Then you can instruct the 'driver' to go away from the fence, or take over. They get the point when it moves painfully slow that they need to turn around. Maybe give them a custom controller, a twist knob and a forward/back stick and some buttons for the actions.
