    Abstract: One embodiment can provide a method and system for configuring a robotic system. During operation, the system can present to a user on a graphical user interface an image of a work scene comprising a plurality of components and receive, from the user, a sequence of operation commands. A respective operation command can correspond to a pixel location in the image. For each operation command, the system can determine, based on the image, a task to be performed at a corresponding location in the work scene and generate a directed graph based on the received sequence of operation commands. Each node in the directed graph can correspond to a task, and each directed edge in the directed graph can correspond to a task-performing order, thereby facilitating the robotic system to perform a sequence of tasks based on the sequence of operation commands.

  • Publication number: 20230209068
    Abstract: Innovations in unified intra block copy (“BC”) and inter prediction modes are presented. In some example implementations, bitstream syntax, semantics of syntax elements and many coding/decoding processes for inter prediction mode are reused or slightly modified to enable intra BC prediction for blocks of a frame. For example, to provide intra BC prediction for a current block of a current picture, a motion compensation process applies a motion vector that indicates a displacement within the current picture, with the current picture being used as a reference picture for the motion compensation process. With this unification of syntax, semantics and coding/decoding processes, various coding/decoding tools designed for inter prediction mode, such as advanced motion vector prediction, merge mode and skip mode, can also be applied when intra BC prediction is used, which simplifies implementation of intra BC prediction.

  • Patent number: 11641109
    Abstract: A grid-forming wind turbine control method for a diode rectifier unit-based offshore wind power transmission system. A control system for controlling a grid-side converter has a three-layered structure, where a first layer is a combination of an active power controller and a reactive power controller; a second layer is a voltage controller; and a third layer is a current controller. The actual reactive power is represented by a per-unit value of a capacity of a corresponding wind turbine unit. The wind turbine units have the same reactive-power reference value, which is constant and does not change with time. The reactive power controllers of all wind turbine units have the same structure and parameters.
