Abstract

Systems and a method for braking an object are provided. An example method, includes determining the expected speed of the object, monitoring the expected speed of the object, and determining if the actual speed of the object is within a preset tolerance of the expected speed. If the speed is not within the preset tolerance of the expected speed, a magnetorheological brake is activated to slow the object.
