SYSTEM AND METHOD FOR DETERMINING UWB BEACON POLE LOCATIONS FOR EXTENDED SERVICE AREAS OF A ROBOT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240085511 titled 'SYSTEM AND METHOD FOR DETERMINING UWB BEACON POLE LOCATIONS FOR EXTENDED SERVICE AREAS OF A ROBOT

Simplified Explanation

The method described in the patent application involves using a wireless side-link to send ranging information and commands to initiate ultra-wideband ranging between a first anchor (initiator) and multiple second anchors (responders) in a service area to be traversed by a robot. The pair-wise range measurements obtained from the responders are used to generate initial location values for all anchors, which are then used to estimate the 3D coordinates of each anchor.

• Identification of initiators and responders in a service area for robot traversal
• Sending ranging information and commands via a wireless side-link for ultra-wideband ranging
• Receiving pair-wise range measurements from responders
• Generating initial location values and estimating 3D coordinates based on range measurements and geometric constraints

Original Abstract Submitted

a method includes identifying a first anchor of a plurality of anchors as an initiator and identifying multiple second anchors of the plurality of anchors as multiple responders, the plurality of anchors located in a service area to be traversed by a robot. the method also includes sending, to the initiator and the responders via a wireless side-link, ranging information and a command to start ultra-wideband (uwb) ranging. the method also includes receiving, from the initiator via the wireless side-link, pair-wise range measurements representing uwb range measurements between the initiator and the responders. the method also includes generating initial location values for the initiator and the responders based on the pair-wise range measurements and one or more geometric constraints imposed on the initiator and the responders. the method also includes estimating 3d coordinates of the initiator and the responders using the initial location values.
