Abstract: Described are automated guided vehicles (AGVs) that can autonomously engage and transport a payload carrier in a human collaborative materials handling facility environment. Embodiments of the present disclosure can be deployed in various materials handling facilities (e.g., a sortation facility, a cross dock center, a fulfillment center, a warehouse, a delivery center, etc.) to facilitate efficient and automated transport of a payload carrier, such as a cart, alongside human workers in unstructured, collaborative environments. Further, the exemplary autonomous vehicle of the present disclosure can engage payload carriers (e.g., carts, etc.) in various configurations and orientations to facilitate multiple modes of transport.

Abstract: Autonomous mobile robots (AMRs) having adaptive safety systems may operate individually or as part of a convoy. During individual operations, an AMR may determine a safety zone and stop responsive to detecting an object within the safety zone. During convoy operations, an AMR may selectively mute a portion of the safety zone and allow a forward AMR of a convoy within the portion of the safety zone. In this manner, the adaptive safety systems may enable convoy operations of multiple AMRs with relatively greater density and greater speed, thereby improving speed and efficiency of AMR operations without negatively impacting safety.

Abstract: An autonomous robot system to enable flexible, safe, efficient, and automated movement of goods and materials in a dynamic environment including one or more dynamic objects (e.g., humans). The autonomous robot system includes a modular autonomous ground vehicle (AGV) including a vehicle management system having a safety management system. The safety management system includes one or more safety management controllers to perform safety functions to enable the modular AGV to operate safely and efficiently alongside humans in a dynamic environment (e.g., a warehouse or fulfillment facility).

Abstract: An inventory management system can include a fleet of mobile drive units. The mobile drive units can detect, using a sensor, calibration data associated with a calibration fixture. The calibration of the sensors can be updated based on the calibration data. The calibration data for the fleet of mobile drive units can be used determine a correction factor. The correction factor can be applied to the fleet of mobile drive units to further update the calibration of the sensors.

Abstract: Disclosed are various embodiments for optimizing robot utilization in autonomous mobile robots by accounting for the battery charge state when assigning missions to be performed by the autonomous mobile robots in a material handling facility. In particular, mission data associated with one or more missions and robot data including a battery charge state associated with one or more robots can be analyzed to determine a robot mission assignment that accounts for battery state charge in order to maximize robot utilization and productivity of material handling tasks.

Abstract: Aspects described herein include an autonomous surface vehicle (ASV) for operation within an inventory system of an environment. The ASV includes a drive system, a docking system, a plurality of sensors, and a memory storing a map of the environment. The ASV further includes one or more computer processors configured to (i) detect, using a location sensor, a location of the ASV within the environment; (ii) control the drive system to actuate the ASV toward a corridor defined in the map at a first speed setting; and control the drive system to actuate the ASV through the corridor along at least one barrier defined in the map. A second, greater speed setting is applied when (i) the location sensor indicates that the ASV is within the corridor and (ii) one or more fiducials along the at least one barrier are visually detected by one or more proximity sensors.
