Samsung patents robot that scans walls to find best spot for projection

This filing describes a robot equipped with a projector and sensors that maps its surroundings to find suitable flat surfaces for displaying images. It ranks these surfaces based on their size and position, then shows the user a preview of the options before projecting the final content onto the chosen area.

Why it mattersIt offers a way for home robots to automatically set up a screen on any available wall or surface without needing a fixed projector mount.

In the filing’s own words

A robot includes: a projector; a sensor; memory storing instructions; and one or more processors, wherein the instructions that, when executed by the one or more processors, cause the robot to: identify candidate projection areas based on first information obtained by sensing surroundings of a user via the sensor; identify a priority order of the candidate projection areas; control the projector to: project a first image at an area including the candidate projection areas, based on positions of the candidate projection areas and the priority order; and display second information on the priority order at the candidate projection areas; identify a candidate projection area selected based on a user input from among the candidate projection areas as a projection area; and project image content at the projection area via the projector.

What exactly they claim (claim 1)

1. A robot, comprising: a projector; a sensor; memory storing instructions; and one or more processors, wherein the instructions that, when collectively or individually executed by the one or more processors, cause the robot to: identify a plurality of candidate projection areas based on first information obtained by sensing surroundings of a user via the sensor; identify a priority order of the plurality of candidate projection areas; control the projector to: project a first image at an area comprising the plurality of candidate projection areas, based on a plurality of positions of the plurality of candidate projection areas and the priority order; and display second information on the priority order at the plurality of candidate projection areas; identify a candidate projection area selected based on a user input from among the plurality of candidate projection areas as a projection area; and project image content at the projection area via the projector, wherein the one or more processors are configured to execute the instructions to cause the robot to: generate a 3-dimensional map of the surroundings based on the first information; identify a plane from the surroundings based on the 3-dimensional map, identify a plurality of areas with a first aspect ratio matching a second aspect ratio of a projection image on the plane, and identify the plurality of candidate projection areas from among the plurality of areas based on a characteristic of the plurality of areas.
