Abstract: A robot control system, a robot control method, and a robot. The robot control system includes a motion control unit configured to perform motion control of a robot, and a rectifier control unit which includes an AC-DC control unit configured to generate a rectifier control signal for driving a rectifier power stage. The rectifier power stage is bcing configured to convert AC power from a grid into DC power. The robot control system also includes a safety control unit configured to generate a safety control signal for selectively turning on or off safety switches connected to an output of the rectifier power stage. The robot control system also includes a motor control unit configured to perform motor control of the robot.

Abstract: The present application relates to a method for robot control. The method includes: obtaining at least one parameter associated with a robot to be controlled by a controller; determining a first identity of the robot based on the at least one parameter; comparing the first identity with a pre-stored second identity; and in response to the first identity matching the second identity, controlling operations of the robot with the controller. The present application further discloses detection of a mismatch between the controller and the robot in an easy, safe and convenient way.

Abstract: Embodiments of the present disclosure provide a method and a controller of controlling a robot. The method comprising detecting a pattern of a series of external forces applied on a portion of at least one arm link of the robot; comparing the pattern with a predetermined pattern associated with the portion; and in accordance with a determination that the detected pattern matches the predetermined pattern, controlling the robot to perform an action corresponding to the predetermined pattern. By introducing a pattern of a series of external forces applied on a robot to control the robot, the control of the robot can be done more intuitively. In this way, some intermediate steps such as conversion of view angle and instructions required to use the HMI-based methods are omitted, thereby improving efficiency or reliability of the robot.

Abstract: Embodiments of the present disclosure provide methods for managing a robot system. In one method, orientations for links in the robot system may be obtained when the links are arranged in at least one posture, here each of the orientations indicates a direction pointed by one of the links. At least one image of an object placed in the robot system may be obtained from a vision device equipped on one of the links. Based on the orientations and the at least one image, a first mapping may be determined between a vision coordinate system of the vision device and a link coordination system of the link. Further, embodiments of present disclosure provide apparatuses, systems, and computer readable media for managing a robot system. The vision device may be calibrated by the first mapping and may be used to manage operations of the robot system.
