Method for drawing map having feature of object applied thereto and robot implementing the same

A robot comprising:

• a motor configured to selectively apply a force to move the robot;
• a memory configured to store a map of a space;
• a sensor configured to scan objects located outside the robot in the space, the objects including a first object, a second object, and a third object;
• and
• a controller configured to:
• calculate position information and feature information on the objects,
• distinguish between the first object through which a signal of the sensor passes from the second object through which the signal of the sensor does not pass based on the position information and the feature information;
• store the position information and the feature information of the objects in the memory, and
• control the motor to move the robot through the space based on the map, the position information, and the feature information,
• wherein the first object is positioned between the robot and the third object, the sensor includes a light detection and ranging (LiDAR) sensor, and the LiDAR sensor includes a laser transmitter, a laser receiver, and a sensed data analyzer, and
• wherein
• the laser transmitter is configured to transmit the signal,
• the laser receiver is configured to receive a first reflection of the signal from the first object and a second reflection of the signal from the third object, and
• the sensed data analyzer is configured to compare an intensity of the first reflection and position information on the first object to an intensity of the second reflection and position information on the third object.
