This is lacking some very critical safety systems such as breakbeam detection (someone walks into the path of a closing door), endstops (the system unexpectedly travels to the end of the track), torque/motor stall monitoring (aka crushing someone to death), and door speed monitor (the door starts moving faster than the motors are moving it)
