Abstract: Systems, methods, and machine readable media are provided for automatic charging and swapping power sources for an Autonomous Vehicle (AV). A determination is made whether a current first power source installed in an AV has sufficient power to complete a task assigned to the AV. In response to determining the first power source has insufficient power to complete the assigned task, the AV is directed to a location of a power source repository. The AV is positioned proximate a power source swapping unit of the power source repository where the first power source is removed from the AV and a second power source stored at the power source repository is installed into the AV.

Abstract: A disclosed system for transporting items to destination locations, for example when receiving inventory at large retail locations, includes a conveyor assembly comprising a plurality of docking locations; an item identifier operable to read identification data; an orchestrator operable to, based at least on the identification data, pair items with transporter solutions; and a sorting controller operable to, based at least on the identification data and the pairings, route items to specific docking locations where transporter solutions are docked. Transporter solutions may include autonomous ground vehicles (AGVs) that bid on delivery tasks and can adjust shelf height in order to facilitate loading and unloading. The AGVs can thus provide an effectively seamless conveyor solution—either rollers on the conveyor surface move items or rollers on the underside of the AGV move the AGV with the items.

Abstract: A disclosed system for transporting items to destination locations, for example when receiving inventory at large retail locations, includes an autonomous ground vehicle (AGV) having at least one shelf; a shelf elevator operable to raise and lower the at least one shelf; a drive unit operable to move the AGV between a docking location and a destination location; the AGV able to position the at least one shelf at a different heights for loading and offloading items first height and a second height different from the first height, autonomously navigate between the docking location and the first destination location, and bid on delivery tasks. Some examples are further able to use a cartridge unit to expand cargo capacity. An AGV could analyze the currently-loaded weight and the remaining available space, and dynamically adjust the heights of the shelves according to the dimensions of the assigned items.

Abstract: Systems and methods for preventing invalid reverse transactions in a distributed environment is provided in which a first block is added to a first cryptographically verifiable ledger containing a transaction identifier and an executable program for preventing a reversal of a transaction. A second block is added to a second unencrypted ledger and contains a flag indicating that the transaction identifier is invalid and a reference to the first block. A notification that the transaction associated with the transaction identifier is being reversed can be received and execution of the executable program for preventing a reversal of the transaction can be triggered. In response to execution of the executable program, the reversal of the transaction associated with the transaction identifier is prevented.

Abstract: Systems, methods, and machine readable media are provided for delivery verification. Delivery of a package is initiated by a courier by submitting an action to a distributed ledger.

The video of the delivery of the package is added to the blockchain. The customer captures any motion detected video of the package occurring after delivery of the package by the courier and this video is added to the blockchain.

Abstract: A system, method and medium for creating an automated shopping and nutrition performance scorecard are discussed. A mobile computing device receives a list of grocery items and supplementary items selected by a user which are transmitted to a nutritional analysis module. The nutritional analysis module retrieves nutritional content information for each item in the list of grocery items and the supplementary items. The nutritional content information is aggregated based on categories. The aggregated categories are transmitted to the mobile computing device and displayed on a graphical user interface. An indication representative of a deviance from a recommended value is displayed for each aggregated category. The GUI provides the user with grocery item recommendations to lower excessive aggregated categories and raise deficient aggregated categories.
