A pool cleaning robot that may include a filtering unit for filtering fluid; a housing that at least partially surrounds the filtering unit; an impeller configured to induce fluid to pass through the filtering unit when rotated at a first direction; a pump motor for rotating the impeller; a drive system; first interfacing elements that are configured to interface with the pool during at least a part of a cleaning process of the pool; and at least one second interfacing element that extends outside a bottom of the housing without reaching a virtual plane defined by bottoms of at least two of the first interfacing elements.

A storage locker for drone delivery provides for weathertight doors that open automatically on sensing the approach of a drone and close to cover the package once deposited by the drone. The storage locker may be operated in conjunction with an elevator to allow elevated placement, removing drones from the vicinity of interfering structures, people, and pets.

A cargo loading system includes a drive unit extending along a length of a cargo area of an aircraft. The drive unit is configured to couple to a modular cargo structure via a handling member and to convey one or more cargo items coupled to the modular cargo structure. The cargo loading system further includes a rotation device and a driver. The rotation device is in contact with the drive unit. The driver is configured to apply torque to the rotation device to cause the drive unit to move the modular cargo structure within the aircraft.

A containment unit that facilitates delivery of parcels using drones is provided. An example containment unit comprises an inner housing unit and an outer housing unit. The inner housing unit includes a first and second sidewall that are connected by an end piece and have a bottom opening in between. The inner housing unit is movable from a retracted position over a floor of the containment unit to an extended position, where a portion of the opening is extended beyond the floor. A parcel may be inserted into a volume of space within the inner housing unit from below through the opening and pulled into the containment unit by the end piece when the inner housing unit is retracted. The containment unit can be used as part of a drone delivery system that can also include an elevated delivery platform, a computer application, or any combination of these aspects.

An elevated delivery platform having a delivery surface that can be placed at a location off the ground to better facilitate delivery of parcels by unmanned aerial vehicles, such as delivery drones, is provided. By placing the elevated delivery platform in an area above the ground, such as atop a home or a pole, a drone is more capable of making deliveries because it avoids obstacles nearer to the ground that typically make drone delivery challenging. The elevated delivery platform raises and lowers parcels to a position where they can easily be retrieved. Some systems also provide a deployable cover to protect parcels from adverse weather conditions while awaiting pickup or following delivery. The elevated delivery platform can be used as part of a drone delivery system that can also include a containment unit, a computer application, or any combination of these aspects.
