Floor doors are divided into two major categories, Semi-Automatic and Automatic Doors.
Semi-automatic doors: Semi-automatic doors open manually but close automatically. When semi-automatic floor doors are selected, then a folding door (BUS type) is placed in the cabin, which is quite reminiscent of opening and closing the door of a bus.
Automatic doors: Automatic doors open and close automatically at the command of the control panel. Automatic door on the floor, automatically means automatic door on the cabin. The cabin door has a sensor that when closed, an obstacle is detected, then it opens again automatically.
