Abstract: Methods for managing a robot arm are disclosed. In one method, during a movement of the robot arm in an axis thereof, a signal collected by a sensor equipped at a frame of the robot arm is received. A change in strength of the received signal is detected, where the change is caused by an offset between a position of a reference mark equipped at the robot arm and a position of the sensor. An original point of the axis of the robot arm is determined based on the detected change. Further, robot systems, apparatuses, systems, and computer readable media for managing a robot arm in the robot systems are disclosed. The original point of the axis of the robot arm may be determined without a dedicated calibrating tool, and then the robot arm may be calibrated based on the original point accurately.

The device includes a bin, platform, conveyor and/or repositioning robot adjacent the outlet end for receiving each single article one at a time as each separate article passes beyond the outlet end.

Abstract: A method for optimizing a predefined policy for a robot, the policy being a Gaussian mixture model. The method begins with an initialization of a Gaussian process, the Gaussian process including at least one kernel k which, as an input parameter, obtains a distance that is ascertained between probability distributions, which are characterized in each case by the Gaussian mixture model and the Gaussian process, according to the probability product kernel. This is followed by an optimization of the Gaussian process in such a way that it predicts the costs as a function of the parameters of the Gaussian mixture model. This is followed by an ascertainment of optimal parameters of the Gaussian mixture model as a function of the Gaussian process, the parameters being selected, as a function of the Gaussian process, in such a way that the Gaussian process outputs the optimal cost function.

Abstract: A system includes a vehicle and a vehicle control system configured to autonomously control one or more operations of the vehicle. The system also includes a navigation receiver configured to identify a location of the vehicle and to provide the identified location to the vehicle control system. To identify the location of the vehicle, the navigation receiver is configured to identify whether navigation signals received by the navigation receiver are spoofed based on angles of arrival for the navigation signals and to suppress any of the navigation signals determined to be spoofed. The navigation receiver may be configured to suppress any of the navigation signals determined to be spoofed in order to prevent an illicit actor from misdirecting the vehicle to an undesired location and/or to prevent an illicit actor from causing the vehicle to make course corrections based on an incorrect current location of the vehicle.
