Robot Localization - So a robot really knows where it is

Robot Localization

Making a Robot know where it is

I started looking into localization for use with sandbot but there have been many other things that conspired to prevent me progressing with it. I put it here as a placeholder and will come back to this when I have more time to think about it..

Slightly more advanced LDR eye

Read this history first, if you have an hour to kill.

The challenge: make your bot rove around your house. Use no active beacons. Use observations by your bot only. Now, does your bot know where it is?

One possible answer: an eye and a brain.

Room Recognition

Each room in the house has a unique lighting situation. A simple eye that looks around in eight directions would "see" a pattern of light and dark segments. Each cell is connected to one ADC on your uC.

LDR Cyclops - holding, scanning, seeking, recalling

Rudimentary LDR eye

Old idea rekindled

This idea about very basic robot vision haunted me ever since I first saw AmandaLDR. Even before it was named after a canine. It's somewhat inspired by the evolution of the first eyes in nature: just a bunch of light sensitive cells on your rump.

Wicked motion/location sensor

Not cheap, no howto, just a commercial product. But great inspiration.

Where are you ?

I want to thank all of you, and Frits especially, for this forum.  I have learned so much here in a short time.

I would like to suggest that everyone include where you are located in your posts, maybe using the Auto Signature.  I think that would add a lot to the experience.

Thank you,
