Abstract

A robotic navigation system for computerized mobile robot. Typically the robot, which may be in an unknown location, will have an onboard internet web server, a capability of establishing a first connection to a remote web browser on the internet for robotic control purposes, and a capability of establishing a second short range bi-directional digital radio connection to one or more nearby computerized digital radio equipped devices external to the robot. Typically at least some of these nearby digital radio equipped devices will have a known location. The robot can exchange short-range bidirectional digital radio signals with nearby devices that have a known location, and obtain location data to determine it'"'"'s position. This location information can be used to assist in robotic navigation. The robot can also navigate to other objects, which also may have an unknown location, using a similar technique in which the object with an unknown location exchanges short range bidirectional digital radio signals with either the robot itself, or other digital radio linked devices with a known location (which then relay the object'"'"'s location to the robot).
