Abstract
A method of sensing a loaded state of articles in a storage bin and a robot implementing the method are provided. The robot senses a loaded state of articles received in the storage bin in real time or at regular intervals and includes the storage bin and storage bin sensors disposed outside the storage bin. The storage bin sensors are arranged at a non-parallel angle relative to a side surface of the storage bin.
Claims20
A robot to accommodate articles, the robot comprising:
- a moving part to move the robot;
- an obstacle sensor on the robot to sense an object located outside of the robot;
- a storage bin located in the robot to receive articles from outside of the robot;
- storage bin sensors disposed outside the storage bin, the storage bin sensors arranged to sense the articles received in the storage bin, the storage bin sensors being arranged at a non-parallel angle relative to a side surface of the storage bin;
- and
- a controller configured to:
- move the robot by controlling the obstacle sensor and the moving part;
- and
- determine whether to replace the storage bin or remove the articles from the storage bin according to a loading height of the articles in the storage bin sensed by the storage bin sensors.

A method of sensing a loaded state of articles received in a robot, the method comprising:
- sensing, by storage bin sensors of the robot, signals output to a storage bin of the robot, the storage bin sensors being arranged at a non-parallel angle relative to a side surface of the storage bin;
- determining, by a controller of the robot, a loading height of the articles received in the storage bin on the basis of the sensed signals;
- determining and storing, by the controller, a loading volume of the articles received in the storage bin according to the loading height of the articles received in the storage bin;
- determining, by the controller, whether to replace the storage bin or remove the articles from the storage bin;
- and
- generating, by the controller, a moving path for the robot to a location where replacement of the storage bin or removal of the articles from the storage bin is performed.
