Method and system for monitoring vibration of robots in an automated storage library
First Claim
1. A storage library having a plurality of media storage cells each housing a media, the storage library comprising:
- a robotic mechanism operable to move to access the media in the media storage cells; and
a vibration sensor associated with the robotic mechanism for generating a vibration signal indicative of vibration of the robotic mechanism.

Abstract
A method and system for the storage and retrieval of media in an automated storage library having media storage cells each housing a single media includes a robotic mechanism. The robotic mechanism is operable to move through the storage library to access the media in the media storage cells. A vibration sensor is associated with the robotic mechanism for generating a vibration signal indicative of vibration of the robotic mechanism. A controller is operable with the vibration sensor for processing the vibration signal to determine if the vibration of the robotic mechanism is abnormal. In the event that the vibration is abnormal, the controller generates a warning signal to warn the operator of the storage library of a possible problem prior to actual failure of the robotic mechanism. The controller is also operable to associated the vibration of the robotic mechanism with particular storage library locations to warn the operator of possible problem locations of the storage library.
