Abstract: Various embodiments enable recovery with a robotic vehicle of an item placed by a user on a delivery pad. The presence of the item on the delivery pad may be sensed and various descriptive recovery parameters may be included in a recovery request. Recovery parameters may be derived from measurements acquired at the delivery pad, information stored in the user account, and information input by a user using an application executing on a user device. The application may be associated with the user account. The recovery request may be sent to a remote server which in turn dispatches a robotic vehicle to the delivery pad site to recover the item and routes the robotic vehicle with the recovered item to a location based on information in the user account. A robotic vehicle selection may be based on the item's weight or one or more of its physical dimensions.

Abstract: Various embodiments enable recovery with a robotic vehicle of an item placed by a user in a delivery area. The presence of the item in the delivery area may be determined using images captured by a camera, with descriptive recovery parameters derived and included in a recovery request. Recovery parameters may also include information stored in a user account and information input by a user using an application executing on a user device. The delivery area and application may be associated with the user account. The recovery request may be sent to a remote server which dispatches a robotic vehicle to the delivery area to recover the item and routes the robotic vehicle with the recovered item to a location based on information in the user account. A selection of robotic vehicle type may be based on the item's weight or one or more of its physical dimensions.
