Samsung patents robot that adjusts laser power to see better

Samsung describes a robot that uses a rotating laser sensor to map its surroundings. The robot switches between low-power and high-power laser pulses to accurately measure the distance to nearby and faraway objects, then uses this data to steer itself.

Why it mattersThis method could help robots navigate more accurately in complex environments by optimizing how their sensors detect objects at different distances.

In the filing’s own words

Provided are a robot driven by controlling a time of flight (TOF) light detection and ranging (LiDAR) sensor, and a driving method thereof. The robot outputs laser pulse signals of the TOF LiDAR sensor by switching a laser pulse signal of a short-range pulse energy and a laser pulse signal of a remote pulse energy, while the TOF LiDAR sensor rotates, corrects information about a distance between the robot and peripheral objects of the robot, based on reflection signals of the laser pulse signals, the reflection signals being received from the peripheral objects of the robot, and controls the driving module to move the robot based on the corrected information about the distance.

What exactly they claim (claim 1)

1. A robot comprising: a driving module; a time of flight (TOF) light detection and ranging (LiDAR) sensor; at least one memory storing one or more instructions; and at least one processor configured to execute the one or more instructions stored in the at least one memory to: obtain information about a distance between the robot and peripheral objects of the robot; determine, based on the obtained information about the distance, to change an energy of a laser pulse signal of the TOF LiDAR sensor to a short-range pulse energy for short-range objects and a remote pulse energy for remote objects; output laser pulse signals of the TOF LiDAR sensor by switching a laser pulse signal of the short-range pulse energy and a laser pulse signal of the remote pulse energy, while the TOF LiDAR sensor rotates; correct the information about the distance between the robot and the peripheral objects of the robot, based on reflection signals of the laser pulse signals, the reflection signals being received from the peripheral objects of the robot; and control the driving module to move the robot based on the corrected information about the distance.
