Abstract: A method for performing tasks on items located in a space using a robot, includes receiving an order to perform a task on at least one item and obtaining a pose associated with the at least one item. The pose is in a coordinate system defined by the space and the pose is where the task is to be performed on the at least one item. The method includes navigating the robot toward the pose associated with the at least one item and detecting, when in proximity to the pose, if the pose is obstructed by an object. If the pose is obstructed by an object, halting the robot at a location spaced from the pose and then causing the robot to provide a first signal indicating that the robot is in a holding mode at the location spaced from the pose.

There is a leg member affixed to the elongated body member at a first angle with respect to the top surface of the elongated body member and extending at least partially along the length of the elongated body member. There is also at least one foot member having a top surface; the at least one foot member affixed to the leg member at a second angle such that the top surface of at least one foot member faces the bottom surface of the elongated body member to define a region for receiving portions of the first and second totes.

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: An electrical charging station for charging an autonomous robot includes a charging station frame having a frame base with a plurality of interconnected frame elements configured to be secured to a floor. One of the frame elements is a front side frame element. There is a charging station cover mounted on the charging station frame and the charging station cover includes a front side cover having a front surface with a charging member. There is a protective member extending across and having a front surface projecting outwardly from the front surface of the front side cover. The protective member is interconnected to the front side frame element through a plurality of apertures in the front side cover and the front side frame element is located adjacent to a back surface of the front side cover, opposite the front surface.

Abstract: A method for estimating a pose of a robot using two co-planar points on an object plane in the environment and two co-planar lines on the object plane, includes capturing with a camera on the robot an image of the object in the environment, including two observed points corresponding to the two co-planar points on the object and two observed lines corresponding to the two co-planar lines on the object; projecting onto the image plane the two co-planar points to obtain two projected points and projecting the two co-planar lines to obtain two projected lines; determining a point projection error by comparing the two projected co-planar points to corresponding observed points; determining a line projection error by comparing the two projected co-planar lines to corresponding observed lines; and estimating a current robot pose if the point projection error and the line projection error are below a predetermined error threshold.

Abstract: A system for determining pose of a lidar sensor in an environment in order to calibrate the lidar sensor. The system includes at least two calibration boards, each having a first edge and a second edge. There is a controller coupled to the lidar sensor to cause the lidar sensor to direct a lidar scan at the calibration boards. The controller causes the lidar sensor to receive a reflection of the lidar scan from the calibration boards and determine locations of a first crossing point on the first edge and a second crossing point on the second edge of the calibration boards. The controller determines a reference plane defined by the first and second crossing points of each of the calibration boards, performs a plane transform of the reference frame to obtain a lidar sensor plane and determine from the lidar sensor plane a pose of the lidar sensor.

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.
