Map recording Algorithms

Hello everybody
can any one tell me what algorithms are used in recording maps used in robots

Hello everybody
what are the detection mechanism used in robots and how to differ between buried and surface mines??

3 threads for the same question? Maybe you would like to use google first?

Google "SLAM" robotics. Simultaneous Localization and Mapping.

Google "arduino sensors" to learn more about the different detection mechanisms available. Google "how to detect a buried mine" and "how to detect a surface mine" to learn more about differing between the two. I imagine you want something like a metal detector.
