Method and apparatus for managing robot arm

An apparatus for managing a robot arm, the apparatus comprising a processor configured to:

• receive, during a movement of the robot arm in an axis of the robot arm, a signal collected by a sensor equipped at a frame of the robot arm;
• detect any of a center and an extremity of a fluctuation in strength of the received signal, the fluctuation in the strength of the received signal being caused by an offset between a position of a reference mark equipped at the robot arm and a position of the sensor equipped at the frame of the robot arm;
• determine an original point of the axis of the robot arm based on the detected center and/or the extremity of the fluctuation in the strength of the received signal;
• and
• calibrate the axis of the robot arm based on the determined original point.

A robot managing system, comprising:

• a robot system comprising:
• a robot arm configured to move in an axis of the robot arm;
• a reference mark equipped at the robot arm;
• a sensor equipped at a frame of the robot arm and configured to collect a signal, the signal having a change in strength that is caused by an offset between a position of the reference mark and the sensor during a movement of the robot arm in the axis of the robot arm;
• and
• an apparatus for managing the robot system, the apparatus comprising a processor configured to:
• receive, during the movement of the robot arm in the axis of the robot arm, the signal collected by the sensor equipped at the frame of the robot arm;
• detect any of a center and an extremity of a fluctuation in strength of the received signal;
• determine an original point of the axis of the robot arm based on the detected center and/or the extremity of the fluctuation in the strength of the received signal;
• and
• calibrate the axis of the robot arm based on the determined original point.
