    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: An electrical charging system including an electrical charger assembly with a charger base coupled to an electrical power source. There is a first male terminal member terminating in a first electrical contact with at least two curved external surfaces and one flat surface. There is a second male terminal member terminating in a second electrical contact with at least two curved external surfaces and one flat surface. There is a cavity formed between the first male terminal member and the second male terminal member having an opening between the first and second electrical contacts. The cavity is defined by the flat surface of the first male terminal member and the flat surface of the second male terminal member. The flat surface of the second male terminal member has a flared surface portion proximate the opening of the cavity and angled relative to the second axis.

    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.
