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: 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: A method and system for data retrieval in an enterprise portal application. The method and system include receiving, in a data access layer, a request for object data from a business logic layer. The method and system further includes validating, by a schema layer in communication with the data access layer, that cache data of a cache and data of one or more databases of the enterprise portal application are synchronized. The cache data may include table data and index data of the one or more databases of the enterprise portal application. The method and system further include retrieving, if the cache is validated, table data from the cache, and returning the object data to the business logic layer, the object data corresponding to the retrieved table data.

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.
