The present invention relates to a method and system for health monitoring of a collaborative robot, includes the steps of 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, and may be applicable as another embodiment.

A state monitoring system for monitoring a state of a robot configured to perform work on a workpiece executes: a step of obtaining state data from a sensor and deriving a deterioration index parameter based on the obtained state data; a step of determining whether or not the deterioration index parameter is greater than a first threshold that is preset to a level lower than a level at which corrective maintenance is required; a step of further determining whether or not a frequency of having determined that the deterioration index parameter is greater than the first threshold is greater than a preset frequency threshold; and a step of suppressing an operation of the robot without stopping the robot if it is determined that the frequency is greater than the frequency threshold.

In an implementation, a robotic system includes a robot, a power source exchange station, and a controller. A method of operation of the robotic system includes identifying by the controller a low-power condition of the robot, and, in response to the identifying of a low-power condition, causing by the controller the robot and the power source exchange station to exchange a first primary electrical power source from the robot for a second primary electrical power source from the power source exchange station. The first and the second primary electrical power source may be a first and a second primary battery, respectively. The robotic system may engage a secondary power source operable to maintain a power supply to the robot during the exchange. The secondary power source may be a secondary battery on-board the robot.

This device includes an acquired data storing unit for storing acquired data about a current command value of a servo motor configuring a robot drive system; a tendency diagnosis unit for diagnosing a future changing tendency of the current command value based on the data of the current command value stored in the acquired data storing unit; and a life determining unit for determining a term until the current command value reaches a previously set value based on the future changing tendency of the current command value acquired by the tendency diagnosis unit. Thus, a residual life of the robot drive system can be accurately predicted.

A failure diagnosing device of a drive mechanism of a mechanical apparatus with a body including a motor, a speed reducer configured to slow down rotational power of the motor, and an operation part configured to operate by the slowed rotational power, and a vibration-proof controller configured to perform a vibration-proof control to prevent vibration of the body, the mechanism including the speed reducer and the motor. The device sends a command for suspending the vibration-proof control to the controller, then identifies an acceleration-and-deceleration period during which operation of the mechanical apparatus of which the control is suspended accelerates and decelerates, and determines whether the mechanism indicates a sign of failure based on a change in a frequency spectrum of load current of the motor or a current value having a correlation with the load current to a change in a rotational speed of the motor during the acceleration-and-deceleration period.
