|The DARPA project LAGR, or Learning Applied to Ground Robots has attracted less public acclaim than the Grand Challenges which serve essentially the same function. Unlike the grand challenges however, LAGR is an attempt to develop an AI which can navigate without the aid of active sensors. No dopplar radar, no scanning lasers, no nothing. Except for a stereoscopic vision system, and a GPS, it has no clue about the outside world at all.
All navigating under LAGR is done by machine vision.
