A passenger assistant system includes an artificial intelligence processing unit, a sensor interface, a flight crew interface, a passenger interface, and at least one end effector. The sensor interface couples the artificial intelligence processing unit with at least one sensor configured to provide environmental information regarding a cabin of an aircraft. The flight crew interface couples the artificial intelligence processing unit with at least one flight crew input. The passenger interface couples the artificial intelligence processing unit with at least one passenger input. The at least one end effector is coupled to the artificial intelligence processing unit. The artificial intelligence processing unit is configured to direct the at least one end effector to perform at least one task responsive to information acquired from one or more of the sensor interface, flight crew interface, or passenger interface.
