Abstract
Brush failure detection on a robotic device for use with a data storage library is accomplished through the use of two brushes drawing power from the same conductor. For example, each brush conducts electrical current between the robotic device and a conductor. Electronics determine operating status of each brush based on a measurement of the difference in current conducted through each brush in the pair of brushes.
