Methods and systems are described that use multiple node-enabled autonomous transport vehicles on a single logistics operation having multiple legs performed by different transport vehicles with enhanced transfer of the item being shipped between such vehicles. A first or primary master node on a first node-enabled autonomous transport vehicle detects a signal from the second master node on a second transport vehicle, navigates to the second transport vehicle based on the detected signal and its direction, and may dock in a transfer configuration. At least one item (or a container with an item) is transferred as payload from the first to the second vehicle using one or more object manipulation systems on respective ones of the first and second transport vehicles. The second vehicle then detects a signal from another node, and navigates to that node as another leg in the multi-leg operation.

Methods are described that perform dispatched store-to-consumer logistics operations for an ordered item using a modular autonomous bot apparatus assembly and a dispatch server. A dispatch command is received from the dispatch server. The different modular components of the bot assembly are verified to be compatible with the dispatched operation and the ordered item is received in a payload area of a modular cargo storage system. The bot assembly autonomously moves from an origin location to a destination location and notifies the delivery recipient of the approach delivery. When delivery recipient authentication input is received that correlates to the authentication information, selective access is provided to the ordered item within the cargo storage system at the destination location. The bot apparatus monitors unloading, and autonomously moves back to the origin location after the ordered item is detected as removed from the cargo storage system.

A modular multiple mobility base assembly apparatus is described for transporting an item being shipped having a base adapter plate and two cooperating and coordinating modular mobility bases that are each coupled to the bottom of the base adapter plate and collectively support the base adapter plate. One of the modular mobility bases operations a master autonomous mobile vehicle, while the other operates as a slave autonomous mobile vehicle that receives propulsion and steering control signals from the master while providing feedback sensor data to the master for use in coordinated and cooperative movement of the assembly apparatus. Each of the modular mobility bases also including respective wireless transceivers through which at least the control signals and sensor data are provided between mobility base units.

A tire noise reduction device includes a sound absorbing member made of a porous material; and a band member disposed between the sound absorbing member and the tire inner surface and provided for attaching the sound absorbing member to a tire inner surface, the band member including chamfered portions on both surface sides at both ends in a width direction of the band member.

Methods are described that perform a dispatched inventory operation related to an inventory item within a modular autonomous bot apparatus assembly and a dispatch server. modular mobile autonomy control module (MAM) receives an inventory dispatch command from the dispatch server and a modular cargo storage system (CSS) receives the inventory item at an inventory hub location. The MAM autonomously causes the assembly to then move to a remote business facility as a destination location, receive authentication input from an authorized delivery recipient, coordinates with the CSS to provide selective access to the inventory item, detects when the inventory item has been removed from within the CSS, and autonomously causes the assembly to move on a return route back to the inventory hub location after removal of the inventory item.

A modular auxiliary power module is described for a modular autonomous bot apparatus that transports an item being shipped. The modular auxiliary power module includes a base adapter platform, a cargo door, an auxiliary power source, and an output power outlet disposed on the base adapter platform as part of a modular component electronics interface. A top side of the base adapter platform has a cargo support area configured to support the item being shipped. Interlocking alignment interfaces (such as channels or latches) are on the top and bottom of the platform. The cargo door is movably attached to and extending from an edge of the base adapter platform, and the output power outlet is coupled to the auxiliary power source and provides access to power for other components of the modular autonomous bot apparatus from the auxiliary power source.

A pneumatic tire includes a plurality of protrusion portions extending along a tire side surface of a tire side portion in a direction that intersects a tire circumferential direction and a tire radial direction; the plurality of protrusion portions each including an intermediate portion in an extension direction that includes a highest position of projection height from the tire side surface, and an end portion on either side of the intermediate portion in the extension direction that includes a lowest position of projection height from the tire side surface. The highest position of projection height of the intermediate portion is in a range of 20% of a tire cross-sectional height from a tire maximum width position to an inner side and an outer side in the tire radial direction, and a ratio of a total width SW and an outer diameter OD satisfies a relationship of SW/OD≤0.3.
