The robots studied the situation for a moment, then rolled the alien off the sled and left with the two men.

The robot turned about and rolled out of the room.

Then, a robot with a camera rolled in, and scanned the house for the suspect.

The robot, which had been sitting silently a few metres away, rolled forward.

The robot had rolled very close to his position and was reaching out with 4 of its arms as though to grasp an invisible enemy.

The robot was too heavy for this and could only roll along the bottom.

The robot did as it was told, and rolled back to the edge of the terrace.

The robot rolled obediently out the door, following his father and West.

The robot rolled past them, and he followed with the rest.

After what seemed like hours the robots released him and rolled silently out of the room with their equipment.
