Abstract: Systems, apparatuses, and methods are described for a food delivery and feeding. An apparatus may comprise: a base; an ejection device configured to eject, via a food outlet on the apparatus, one or more of a plurality of food items; and a rotation device operably mounted to the ejection device. The rotation device may be configured to rotate the ejection device relative the base to cause a change to a direction of ejection of the one or more of the plurality of food items relative to the base. The rotation device may comprise a motor and a ring gear. The motor may be connected to the ring gear. The ring gear may be connected to a bracket assembly. The rotation of the bracket assembly may cause the rotation of the ejection device.

Abstract: The present invention relates to a control method, device, and storage medium for an intelligent door lock. The method comprises: detecting, by a computing device, a target signal associated with an unlocking object; parsing the identification information of the unlocking object from the target signal; based on determining that the identification information is the target identification information, obtaining a first image of the unlocking object; determining whether the unlocking object is a target object based on the first image; and based on determining that the unlocking object is determined to be the target object and detection of an unlocking action, controlling the intelligent door lock to unlock.

Abstract: Systems, apparatuses, and methods are described for a food delivery and feeding. An apparatus may comprise: a housing, the housing comprising a housing outlet; and a storage compartment contained within the housing the storage compartment configured to store a plurality of food items for feeding one or more pets. The storage compartment may comprise a storage compartment outlet and two rotatable wheels. The apparatus may also comprise an ejection device contained within the housing. The ejection device may be configured to eject one or more of the plurality of food items. Rotation of the two rotatable wheels causes the one or more of the plurality of food items to move from the storage compartment through the storage compartment outlet to the ejection device.
