Abstract
A method and system for health monitoring of a collaborative robot are provided. The method includes calling a test program installed in a collaborative robot for health monitoring of the collaborative robot when the collaborative robot satisfies a call condition of the test program, performing a test by operating the collaborative robot based on the test program, and collecting and analyzing a result of the test by the collaborative robot.
Claims5
A method for monitoring health of a robot, the robot comprising a joint, a memory, and a controller programmed to control the robot to perform tasks in connection with humans, the method comprising:
- performing a first test for the joint based on a test program under a predefined control condition, the test program designed for the joint;
- performing a second test for the joint multiple times under the same predefined control condition;
- generating test data comprising sensing data multiple times, each set of test data corresponding to the first test and the second test;
- generating a data monitoring graph based on a temporal change in the sensing data;
- and
- displaying the data monitoring graph;
- wherein the predefined control condition comprises a data condition, an action condition, a load condition, an operating condition, and an environmental condition,
- wherein the data condition is configured to acquire the information sensing data using a prescribed sensor,
- wherein the action condition is configured to acquire the sensing data when the robot performs a prescribed operation,
- wherein the load condition is configured to acquire the sensing data when the robot operates with a prescribed load and a motion pattern,
