Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: registering one or more aerial vehicles and one or more land-based vehicles with a last mile delivery system, where the one or more aerial vehicles and the one or more land-based vehicles are associated with aerial vehicle information and land-based vehicle information, respectively; determining to generate a land-based vehicle transportation request for a first aerial vehicle that is performing a delivery; matching, based on the land-based vehicle transportation request and the land-based vehicle information, the first aerial vehicle with a first land-based vehicle; and generating and sending transportation instructions to the first aerial vehicle and the first land-based vehicle, where the transportation instructions include: (i) a starting location where the first aerial vehicle docks to the first land-based vehicle, and (ii) a destination to which the first land-based vehicle transports the first aerial vehicle.

Abstract: An apparatus for teaching a person a technique for striking a volleyball. The apparatus has a chute with first and second side walls for directing volleyball toward a pivotable arm attached to the chute. A passage in the arm connects a cone thereon with a source of vacuum while the weight of a valve on the arm positions the arm in a vertical position. An indexing member sequentially retains volleyballs in the chute and sequentially presents a volleyball to the cone. An input acts to release a lock on the indexing member and thereafter allow a volleyball to roll from the chute toward the cone where the vacuum sucks the volleyball onto the cone. The weight of the volleyball causes the arm to pivot from the vertical position and rotate the volleyball to a position for a player to spike the volleyball.
