    Abstract: A plurality of sensors of the same composition or different compositions are provided on a substrate or in a bundle and are sensitive to a plurality of constituent species in a mixed species medium being measured. The sensors of the same composition may each be maintained at different temperatures. The sensors of different compositions may each be maintained at the same temperature or different temperatures. The intersection of measurement values from the plurality of sensors may be used to determine the actual concentrations of the constituent species (e.g., hydrogen and oxygen) in the mixed species medium.

    Abstract: A system and method for predicting the location at which a feature that is being tracked during a robotic assembly operation will be located within one or more images captured by a vision device. A vision device can be mounted to a robot such that the location of the vision device as the robot moves can be known or determined. In the event of an interruption of the tracking of the feature by the vision device as the corresponding workpiece is moving, the location of the feature relative to a vision device can be predicted, such as, via use of current or past historical movement information for the feature and/or the associated workpiece. Using the predicted location of the feature and the known location of the vision device, the location at which the feature will be located in an image(s) captured by the vision device can be predicted.

    Abstract: A system and method for automatic recovery from a failure in a robotic assembly operation using multiple sensor input. Moreover, following detection of an error in an assembly operation from data provided by a first sensor, a recovery plan can be executed, and, if successful, a reattempt at the failed assembly operation can commence. The assembly stage during which the error occurred can be detected by a second sensor that is different from the first sensor. Identification of the assembly stage can assist with determining the recovery plan, as well as identifying the assembly operation that is to be reattempted. The failure can be detected by comparing information obtained from a sensor, such as, for example, a force signature, with corresponding historical information, including historical information obtained at the identified assembly stage for prior workpieces.

    Abstract: A method of automated in-hand calibration including providing at least one robotic hand including a plurality of grippers connected to a body and providing at least one camera disposed on a periphery surface of the plurality of grippers. The method also includes providing at least one tactile sensor disposed in the at least one illumination surface and actuating the plurality of grippers to grasp an object. The method further includes locating a position of the object with respect to the at least one robotic hand and calibrating a distance parameter via the at least one camera. The method also includes calibrating the at least one tactile sensor with the at least one camera and generating instructions to grip and manipulate an orientation of the object via an image feed from the at least one camera for a visualization of the object.

    Abstract: A light emitting diode (LED) sensor including a first LED device disposed on a support and configured to emit a radiation, and a second LED device disposed on the support and configured to receive the emitted radiation. A structure is formed on the support, the first LED device, and the second LED device. The structure defines a contoured surface. A material is located adjacently to the contoured surface, wherein the material includes a property adapted to reflect the emitted radiation from the first LED to the second LED. The structure includes an ellipsoid and the contoured surface defines an ellipsoidal surface. First and second foci are defined by the ellipsoid, wherein emitted radiation from the first LED device converges at the first foci and the second foci and is reflected to the second LED device. The device is configured to determine a temperature or a chemical property of an analyte.

    Abstract: A system and method that automatically resolves conflicts among sensor information in a sensor fusion robot system. Such methods can accommodate converging ambiguous and divergent sensor information in a manner that can allow continued, and relatively accurate, robotic operations. The processes can include handling sensor conflict via sensor prioritization, including, but not limited, prioritization based on the particular stage or segment of the assembly operation when the conflict occurs, overriding sensor data that exceeds a threshold value, and/or prioritization based on evaluations of recent sensor performance, predictions, system configuration, and/or historical information. The processes can include responding to sensor conflicts through comparisons of the accuracy of workpiece location predictions from different sensors during different assembly stages in connection with arriving at a determination of which sensor(s) is providing accurate and reliable predictions.
