1. A door positioning apparatus, comprising:
a baseplate configured to be coupled to a bottom portion of a door;
a main motor;
a circuitry electrically coupled to the main motor and configured to be in communication with a remote computing device;
a drive member coupled to the main motor and the circuitry, the drive member comprising an external surface, the external surface of the drive member configured to contact a surface adjacent the door; and
the drive member moveably mounted to the baseplate through at least one spring element to allow the drive member to move upward and downward relative to the baseplate, the at least one spring element biasing the drive member away from the baseplate to maintain contact with the ground surface during operation of the door positioning apparatus;
the main motor configured to be remotely activated by the remote computing device to engage the drive member to contact the surface adjacent the door to reposition the door responsive to receipt of a signal, further comprising:
a doorknob motor;
doorknob circuitry electrically coupled to the doorknob motor and configured to be remotely connected to the remote computing device;
a power transmission assembly coupled to the doorknob motor and configured to translate a rotational movement of the doorknob motor to a linear movement of a latch mechanism responsive to receipt of the signal.
