Hi Everyone,
I want to build a robot like a i-Robot Roomba which can back to its dock when running out of battery. But i don't know what sensor to use for the robot to locate its dock place. i'd read one article, they use infra red beam, but the robot cannot detect the beam if the beam avoid by an obstacle.
can anyone suggest me good sensor for that?
