    Abstract: Concepts of an omnidirectional pinion wheel are described. In one embodiment, the wheel includes a hub, first and second annular rims each including inner and outer rim surfaces, spokes that extend from the hub to the first and second annular rims, a pinion ring including pinion rods that extend between the inner surfaces of the first and second annular rims, and first and second annular rings of rollers affixed on the outer surfaces of the first and second annular rims. Using an axis of freedom of the rollers, the wheel can move sideways in addition to forward and backward. Further, when used with a vertical rack gear, the wheel can provide vertical displacement by engagement between teeth of the gear and the pinion ring. Additionally, various racks and tracks with teeth for pinion ring engagement are described along with an example vehicle capable of vertical displacement using the wheels.

    Abstract: Systems and methods are provided herein for operating a conveyance system (e.g., a conveyor belt, tilt plane, robotic arm) of a mobile drive unit (MDU) independent of the MDU's navigation system. The MDU may be configured to obtain, convey, and deliver items within the workspace. Navigation information related to navigating the MDU within a workspace may be obtained. Operations of a navigational system of the MDU may be performed to move the MDU to various locations within the workspace in accordance with the navigation information. Conveyance information related to physically obtaining and/or delivering an item within the workspace may be obtained by the MDU (e.g., via conveyance-related fiducial markers and/or sensors of the MDU). At least one operation of a conveyance system of the MDU may be executed which may cause the item to be physically relocated based at least in part on the conveyance information.

    Abstract: An example storage module may include an upper support structure, a lower support structure, and a frame. The upper support structure may engage with a corresponding lower support structure of a first different storage module. The lower support structure may engage with a corresponding upper support structure of a second different storage module. The frame may include a first component and a second component. Each component may include an upper portion, a lower portion, and a set of connecting portions. The upper portion may define an upper level of the storage module. The lower portion may define a lower level of the storage module. The set of connecting portions may connect the upper and lower portions. The storage module may also include a set of carrier devices to move in accordance with a movement path and support a set of storage containers.

    Abstract: Systems and methods for determining strategy modes for autonomous vehicles are described. An autonomous vehicle may detect aspects of other vehicles and aspects of the environment using one or more sensors. The autonomous vehicle may then determine strategy modes of the other vehicles, and select a strategy mode for its own operation based on the determined strategy modes and an operational goal for the autonomous vehicle. The strategy modes may include an uncoupled strategy mode, a permissive strategy mode, an assistive strategy mode, and a preventative strategy mode. The autonomous vehicle may further determine elements in the environment and topological constraints associated with the environment, and select the strategy mode for its own operation based thereon.

    Abstract: Systems and methods for operating autonomous vehicles are described. An autonomous vehicle may detect strategy modes and/or actions of other vehicles in a local environment. The autonomous vehicle may then select a strategy mode for its operations based on the detected strategy modes and/or actions of other vehicles, and based on an operational goal for the autonomous vehicle. The strategy modes may include an uncoupled strategy mode, a permissive strategy mode, an assistive strategy mode, and a preventative strategy mode. The autonomous vehicle may further select an action for its operations based on the selected strategy mode.
