Abstract: Systems and methods are provided for robot congestion management including a robot monitoring server configured to track a location of a plurality of robots within a navigational space and a plurality of robots in communication with the robot monitoring server, each robot including a processor and a memory, the memory storing instructions that, when executed by the processor, cause the autonomous robot to determine, from a task list assigned to the robot, a first pose location corresponding to a first task, receive, from the robot monitoring server, congestion information associated with the first pose location, identify a congested state of the first pose location indicated by the congestion information, select, responsive to the identification of the congested state, a second task from the task list, and navigate to a second pose location corresponding to the second task.

Abstract: Processes are provided for dynamically sorting and storing items in a warehouse without the need for presorting items and without delaying or negatively impacting the efficiency of operators in the warehouse. Items are individually scanned and placed in totes of a tote-array provided on a mobile robot. An optimized route is calculated based on the items in the tote-array, and the robot navigates to a first location on the route. When the item has been put away, a replacement item is placed in the just-emptied tote of the tote-array, and an updated route is calculated. A robot capable of navigating to predefined locations for storing items is a warehouse is provided.

Abstract: A method for rolling shutter compensation for a camera sensor mounted on a moving vehicle includes estimating, based on a plurality of images of an object, a speed and a direction of movement of the vehicle; acquiring an additional image of the object having four corners; estimating a location of each of the four corners of the object in an image plane defined by the additional image; determining a corrected location in 3D space for each of the four corners of the object; determining a first compensated location for each of the four corners of the object in the image plane; determining a second compensated location for each of the four corners of the object in the image plane; and determining a difference between the first compensated locations of the four corners of the object and the second compensated locations of the four corners of the object.

Abstract: Systems and methods for contextually mapping zones within a space for regulating robotic navigation within the space include defining, by at least one fiducial marker positioned within the space, a zone within the space, associating a rule with the zone, the rule at least partially dictating operation of one or more robots within the zone, and operating the one or more robots within the zone consistent with the rule.

Abstract: Systems and methods for proximate robot object detection and avoidance are provided herein which include a receiver in electronic communication with an autonomous robot and configured to receive a broadcast message from a beacon, a processor, and a memory, the memory storing instructions that, when executed by the processor, cause the autonomous robot to detect, based on the received broadcast message, a proximity of the beacon to the autonomous robot, determine, from the received broadcast message, a beacon status, the beacon status indicating whether the beacon is stationary, approaching the autonomous robot, or withdrawing from the autonomous robot, identify, according to the detected proximity and the determined beacon status, a corresponding proximity operation, and control the autonomous robot to stop an ordinary operation and operate according to the identified proximity operation.

Abstract: A method for predicting a collision between a mobile robot and an obstacle in an environment includes obtaining laser scan data for the mobile robot at a current location in the environment. The method also includes predicting a future location of the mobile robot in the environment and producing predicted laser scan data corresponding to the future location of the mobile robot in the environment. The method further includes assessing the predicted laser scan data relative to the mobile robot at the current location to determine whether a collision with an obstacle is predicted.

Abstract: A mobile robot configured to drive on a surface with irregularities, comprising: a chassis having a front end facing a forward direction of travel, a back end, a first side, and a second side. There is a first drive wheel rigidly affixed to the chassis proximate the first side and interconnected to a motor to propel it. There is a second drive wheel rigidly affixed to the chassis proximate the second side and interconnected to a motor to propel it. A first caster assembly is rigidly affixed to the chassis proximate the front end and includes a first caster wheel configured to rotate about a first swivel axis. A second caster assembly is rigidly affixed to the chassis proximate the back end and includes a second caster wheel configured to rotate about a second swivel axis and it includes a compliant member to absorb the irregularities.

Abstract: A method for executing an order with a plurality of items assigned to a first robot of a plurality of robots operating in a warehouse with the assistance of a plurality of operators. The method includes navigating the first robot to a first location in the warehouse proximate a location of a first item in the order and pausing for an operator of to assist the first robot to execute a function. The method includes determining if the first robot has been paused for greater than a maximum dwell time without being assisted by an operator. If it has been, the method causes the first robot to leave the first location without completing the function on the first item and causing the first robot to proceed to a second location proximate a storage a second item to execute a function.
