I have always wanted to build/design a mobile robotics platform for various tasks around the house/yard, even a contruction site. The biggest problem that I have run into is a getting a positioning system that will give me accurate positioning (+-2 inches). There are some really expensive GPS systems, in the thousands of dollars. I don't think that is realistic or cost effective to put in a robotic lawnmower. I was trying to come up with my own system using wifi or zigbee nodes to triangulate the position of the robot. I don't know if this is possible for the resolution that I want or if someone else has already tried it. Any thoughts or info would be great.
