Abstract: A functional assembly for an industrial robot includes a safety cover which selectively covers an operative unit or robot end effector. The cover includes a fixed portion and a movable portion which selectively moves relative to the fixed portion. The movable portion selectively moves to cover or uncover a portion of the operative unit for the operative unit to function for its intended purpose. The operative unit can move in two directions orthogonal to the movement of the cover movable portion allowing the operative unit to travel or reach to the full footprint of the cover. The safety cover may include sensors to detect objects in close proximity to the safety cover to slow or stop the robot or functional assembly.
