Excavator for detecting rotation of upper body considering detected dead zone and operation method thereof

An excavator, comprising:

• a lower body;
• an upper body rotatably mounted on the lower body;
• a sensor device configured to collect sensing information related to a rotation angle of the upper body relative to the lower body, the sensing information including a dead zone in which the rotation angle is incorrectly provided;
• and
• a processor electrically connected to the sensor device, wherein the processor is configured to:
• detect occurrence of the dead zone based on the sensing information collected by the sensor device;
• correct the sensing information in response to detection of the occurrence of the dead zone;
• and
• calculate the rotation angle of the upper body based on the corrected sensing information,
• wherein the processor is further configured to initialize the sensor device while rotating the upper body at a reference speed when a number of errors greater than or equal to a threshold value,
• wherein the processor is further configured to:
• determine the occurrence of the dead zone when a rotation change amount, which is a difference between first sensing information in a current frame period and second sensing information in a previous frame period, with a reference change amount exceeds the reference change amount;
• or
• determine the occurrence of the dead zone when the sensing information exceeds a reference measurement range which is a sensing range of the sensor device.
