I meant the error due to things like refraction around solid objects, reflections, etc. Also - I didn't mean estimating and correcting for it at runtime - I just wanted an idea of what sort of magnitude of error those effects presented.

(...) needs (...) uncompressing (...) Run-Length-Encoding (RLE) should work well on a blobby black-and-white map. Or you could store line N as the difference (or XOR) between line N and line (N-1). The difference would be mostly zero. Then RLE it. (...) (23 years ago, 27-Jun-02, to lugnet.robotics)

I've been thinking a bit about using landmarks imitating ants. You should know that ants use different types of self-produced chemicals to mark the places they have been and the paths to follow. Using this with robots would mean using a light sensor (...) (23 years ago, 27-Jun-02, to lugnet.robotics)

Thanks, Just to make sure, let's take an example. Let's say that I have two RCX, named A and B. What if the program in RCX B is waiting for a character on the instruction KEY and RCX A sends a character, let's say '5' (ASCII 52) with 52 EMIT ? That (...)
