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. Chris' ramb…

I’m probably dense but if I’m probably dense but if the general idea is to do room identification, then I have an uneasy feeling that the absolute position of the robot is assumed. I know at my house, depending on the position of a hypothetical LDR sweeper, within a room, you c…

**I assume the goal ** is not only room identification, but to teach the bot to recognize a room based on it’s own repeated analysis of inputs? the way us organic meatbags do it? So wouldn’t barcodes or color stripes, etc, sort of defeat that? or am i reading too much into it? …

that is not the goal that is the appeal of this setup its simplicity and analogy to us just is too friggin’ beautiful [and reading “us organic meatbags” made me think of biodegradable packaging material for American food - nice confusion in the early morning]

Many alternatives are being discussed here You will like reading it. You will be, like, reading it.

**Would ** Using sound rather than light be more accurate? I.e the bot drives into a room, makes a sonar like click and then gets teh echo back, measures the difference int it and uses that as a finger print for the room. In a large room the sound would take longer to retu…

Snowflakes Sorry, I’ve only skimmed this very long and interesting thread. Here’s a variant that I think Joe was reaching for. Put snowflake codes onvertical edges that aren’t likely to get repositioned - eg door frames and cupboard corners. Snowflake codes are like bar codes bu…

I agree Way back last week, I thought we were trying to suggest ways for a free range bot to understand/map its environment. As soon as we help it by leaving signs all over the palce its no-longer free range. No matter, this problem is still interesting and perhaps more solvable…

perhaps This design (oops, forgot airquotes) aims to be engineered in a very simple computer, using the cheapest possible sensors. I won’t challenge you to prove cost effectiveness of your proposal, but for now I’m thinking it would require a lot more computing power, more compl…
