Data management method and device for diagnosing defect of collaborative robot

A method for managing data for diagnosing a defect of a collaborative robot, comprising the steps of:

• generating, by an electronic device, a sensing data structure for managing sensing data collected from at least one collaborative robot;
• generating, by the electronic device, an operation data structure for managing operation data associated with the operation of the collaborative robot;
• generating, by the electronic device, a failure data structure for managing failure data at a time point when the operation has a severity that is greater than or equal to a threshold value;
• storing, by the electronic device, data collected from the at least one collaborative robot according to the structure and
• diagnosing a defect or failure of the collaborative robot,
• wherein the step of generating an operation data structure comprises the steps of:
• checking the operation data at a time point when the operation occurs in the collaborative robot;
• and
• defining the severity of the operation of the collaborative robot as level 1, level 2 and level 3 based on the operation data,
• wherein the step of diagnosing a defect or failure of the collaborative robot comprises the steps of:
• generating the failure data by combining the sensing data and the operation data at a time point when the operation data is collected, when the severity of the operation for operation data collected from the collaborative robot corresponds to any one of level 2 and level 3 and the failure data further includes the sensing data and the operation data corresponding to a time period before and after the time point;
• and
• confirming a time point when a defect or failure of the collaborative robot has occurred based on the failure data.
