Abstract
A rollup barrier is provided for a robotic station. The barrier includes a track having a tapered portion at its lower end. A switch is mounted at the extreme lower end of the track. The switch prevents actuation of the robotic equipment unless the barrier is moved to its extreme lowermost position. Extensible cylinders are used for connection to a chain trained around a sprocket in order to roll the roller.
