Abstract

See full text

A method for computing a quality location estimate of a delivery robot by creating an ad-hoc network that can include one or more autonomous delivery vehicles, nearby infrastructure such as 5th Generation signal transceivers, vehicle-to-infrastructure (V2I) enabled autonomous vehicles, and millimeter-wave device components in Line-Of-Sight (LOS) with any of the above communicating devices. The method can include estimating the quality for localization (e.g., dilution of precision), and steering the robot delivery vehicle via a vehicle-to-anything (V2X) antenna disposed on the robot delivery vehicle and/or repositioning the autonomous delivery vehicle itself to obtain maximum positioning accuracy. The location estimates computed by the vehicle are sent to the delivery robot which then fuses these estimates with its onboard sensor values. The method may assist localization based on a 2D occupancy map to enhance the positioning performance and provides robust localization mechanism without expensive 3D sensors.
