Bob,

Thanks for the input. You don’t happen to have any pictures or video of your robot, do you? I’d love to see some.

I can definitely see the limitations of this implementation, but coupled with other means of navigation, it might be useful. I can also see how it can be used in specific situations – perhaps hospitals?

I tried doing this a couple of years ago, and it does work but only in corridor type situations. Notice in this case that the black stripe at door handle height is providing a strong cue.

It turns out that there are plenty of situations in a home or office environment where vanishing points cannot be easily computed.
