Embodiments of present disclosure relate to adjusting a robot motion path. In the method for adjusting a robot motion path, a first processing procedure may be performed on a first workpiece to obtain a first product. Then, first process data may be obtained, where the first process data describes an attribute of the first processing procedure for obtaining the first product from the first workpiece. Next, based on the obtained first process data, a robot motion path of a second processing procedure that is to be performed on the first product by a robot may be adjusted. Further, embodiments of present disclosure provide apparatuses, systems, and computer readable media for adjusting a robot motion path.

A method, system and apparatus of determining search parameters for welding seam point calibration. The method includes determining, for a seam vertex point on a welding seam, three reference faces which are perpendicular to each other, based on geometry of an object to be weld in a virtual model; and determining a start point and a search point of a search motion for welding seam point calibration based on the three reference faces and predetermined criteria respectively for the start point and the search point. Three reference faces can be extracted automatically, and search parameters needed for the search instructions can be determined based thereon which enables automatic generation of search instructions and thus the time, manpower and cost for the welding seam point calibration can be reduced greatly.

A method for calibration of work piece mounted in a predetermined manner to a work object and a robot system using the same. The work object has a first surface, a second surface and a third surface, and wherein the work object frame of reference is defined by a first coordinate line, a second coordinate line, and a third coordinate line at intersections of the first surface, the second surface and the third surface converging on a point. The method includes: touching a first number of locations on the first surface of the work object positioned by the robot touch probe to measure their actual locations on the first surface in the robot frame of reference, and storing the measured first coordinates for the measured locations; touching a second number of locations on the second surface of the work object positioned by the robot touch probe to measure their actual locations on the second surface in the robot frame of reference, and storing the measured second coordinates for the measured locations; touching a third number of locations on the third surface of the work object positioned by the robot touch probe to measure their actual locations on the third surface in the robot frame of reference, and storing the measured third coordinates for the measured locations; calculating orientation and origin of the work object frame of reference from the robot frame of reference based on the measured first, second and third coordinates for the measured locations, where the work object is positioned in the robot cell. The method provides all the necessary data to determine orientation and origin of the actual work object frame of reference relative to the robot frame of reference. The method also enables the robot to perform machine operations accurately at locations on a work object.

A method and an apparatus for optimizing a target working line are disclosed. The target working line includes at least one robot manipulator, at least one conveyor and at least one item on the conveyor to be displaced by the robot manipulator. The method includes: obtaining an evaluation model for the target working line, the evaluation model yielding an overall success rate of moving the item from one conveyor to another conveyor based on at least one measuring parameter, the measuring parameter being a physical attribute of the target working line; yielding the overall success rate for the target working line as a function of a value for the measuring parameter for the target working line; and in case that the yielded overall success rate is lower than a predetermined threshold rate, updating a value for a configuring parameter based on the overall success rate, the configuring parameter corresponding to the measuring parameter, and the configuring parameter being states of the working line. The optimization of the evaluation model does not require an implementation of an on-site process or an involvement of an experienced engineer or worker. Instead, simulation software can be used to obtain customized parameters used for the target working line, resulting in an increased success rate within a short period of time.
