  • Patent number: 11417238
    Abstract: 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.

  • Patent number: 11312019
    Abstract: 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.

  • Publication number: 20220088783
    Abstract: Methods for simulating an object in a manufacturing line, wherein the object is placed on a conveyor in the manufacturing line. In the method, a position of the object is obtained from object data collected by a camera device deployed in the manufacturing line. A movement of the conveyor is determined from a controller of the conveyor. An object position of the object is obtained based on the determined position and an offset of the object caused by the movement of the conveyor. A virtual representation of the object is displayed at the determined object position in a virtual environment. With the virtual environment, the administrator of the manufacturing line may be provided with accurate states of the manufacturing line, based on which operations of a robot system that is to be deployed in the manufacturing line may be estimated.

  • Publication number: 20220088784
    Abstract: Embodiments of the present disclosure provide methods for monitoring a robot system including a robot arm for processing at least one object. In the method, an arm position of the robot arm may be obtained from a controller of the robot arm. An object position of one of the at least one object may be obtained from object data collected by a camera device. The robot system may be monitored by displaying a virtual representation of the robot arm and a virtual representation of the object based on the obtained arm position and the object position, respectively. Further, embodiments of present disclosure provide apparatuses, systems, and computer readable media for monitoring a robot system. With these embodiments, the robot system may be monitored in an easy and effective way even if the robot system is built in an environment with a narrow place and/or with inadequate light.
