Artificial Intelligence for Robotics

Summary

This chapter introduced some concepts for robot navigation in an unstructured environment, which is to say, in the real world, where the designers of the robot don't have control over the content of the space. We started by introducing SLAM, along with some of the strengths and weaknesses of map-based navigation. We talked about how Roomba navigate, by random interaction and statistical models. The method selected for our toy-gathering robot project, TinMan, combined two algorithms that both relied mostly on vision sensors.

The first was the floor finder, a technique used by the winning entry in the DARPA Grand Challenge. The FFA (Floor Finder Algorithm) uses the near vision (next to the robot) to teach the far vision (away from ...
