AI Technical Summary

Technical Problem

Existing household robots face challenges in precisely determining the spatial location and pose of household appliances, especially when they are obscured by panels or have unknown appearances, which hinders reliable interaction.

Method used

A device and method for a household robot to determine the spatial location and pose of appliances using sensor data from cameras, lidar, radar, and radio signals, combined with transformation techniques to align the appliance's coordinate system with the robot's reference system, and optionally altering the appliance's appearance for better detection.

Benefits of technology

Enables efficient, robust, and precise localization of household appliances, allowing reliable interaction by determining the appliance's position and orientation with high accuracy, even when hidden or visually unclear.

Abstract

A device (101) for a household robot (100) is described, which is configured to interact with a household appliance (110). The device (101) is configured to determine position information with respect to N distinct reference points of the household appliance (110), with N ≥ 1, in particular with N ≥ 2, wherein the position information specifies the spatial location of the N distinct reference points relative to the household appliance (110). Furthermore, the device (101) is configured to determine measurement information with respect to the N distinct reference points of the household appliance (110) based on sensor data from one or more sensors (102, 105) of the household robot (100), wherein the measurement information specifies the spatial location of the N distinct reference points relative to the reference coordinate system of the household robot (100).The device (101) is further equipped to determine position information relating to the spatial location of the household appliance (110) within the reference coordinate system based on position information and measurement information.
