Wireless tag detection and localization by a mobile robot

This invention describes a mobile robot designed to patrol commercial or industrial buildings. It uses an antenna to detect wireless tags on objects as it moves through an area. The robot's controller plans its route, either to cover the area as quickly as possible or to find the most tags.

Why it matters: Filed before widespread adoption of advanced autonomous mobile robots and sophisticated AI-driven path planning. The intervening years have seen significant improvements in robot navigation and optimization algorithms, making the route selection claims more feasible and efficient.
