Samsung patents robot speed control based on obstacle viewing angle

Patent drawing from the official filing.

Samsung has been granted a patent for an electronic device that uses sensors to measure the distance to obstacles while moving. The device calculates its 'viewing angle' to these obstacles and slows down if the angle becomes too narrow or changes rapidly, helping it navigate safely.

Why it mattersThis improves how autonomous devices like delivery robots or vacuum cleaners handle tight spaces by adjusting speed based on how much of the environment they can see.

In the filing’s own words

An electronic apparatus includes a sensor and a processor configured to acquire distance information about a distance of the electronic apparatus to a sensed obstacle in a different direction based on a travel direction of the electronic apparatus and sensing data received from the sensor during a travel of the electronic apparatus, identify a viewing angle of the electronic apparatus based on the acquired distance information, and adjust a travel velocity of the electronic apparatus based on the identified viewing angle being less than a threshold value.

What exactly they claim (claim 1)

1. An electronic apparatus comprising: a sensor; and a processor configured to: acquire distance information about a distance of the electronic apparatus to a sensed obstacle in a different direction based on: a travel direction of the electronic apparatus, and sensing data received from the sensor during a travel of the electronic apparatus, identify a viewing angle of the electronic apparatus based on the acquired distance information, adjust a travel velocity of the electronic apparatus based on the identified viewing angle being less than a threshold value, identify a change in the viewing angle based on the travel of the electronic apparatus in real time, and reduce the travel velocity of the electronic apparatus by a first predetermined ratio for a predetermined time based on a change ratio of the change in the viewing angle being the threshold value or more.
