Abstract: Some embodiments of the disclosure disclose a space assembly system based on fusion of on-orbit additive manufacturing and ground-based launch. In some examples, an operator establishes a space manufacturing center to achieve on-orbit manufacturing of spacecraft structural components and assembles the components manufactured on orbit with spacecraft enabling modules launched from the ground to form a target spacecraft. The system includes a physical subsystem, a digital twin subsystem, and a communication subsystem. The physical subsystem includes a control unit, a communication unit, a sensor unit, an imaging and positioning device, a data storage unit, a data processing unit, an additive manufacturing unit, a space robot unit, and a raw material bin. The digital twin subsystem remotely monitors the physical subsystem. The communication subsystem establishes a connection between the physical subsystem and the digital twin subsystem and a connection between all units and devices of the physical subsystem.

Abstract: Provided are an intelligent obstacle avoidance method and apparatus based on binocular vision, a robot and a medium. The method includes acquiring, through a binocular camera, a depth map of a work scene in a moving direction of a robot, and calculating a height map corresponding to the work scene according to the depth map; determining first obstacle information in the work scene according to the depth map and determining second obstacle information in the work scene according to the height map; determining a target obstacle existing in the work scene and position information of the target obstacle according to the first obstacle information and the second obstacle information; and controlling the robot to perform obstacle avoidance according to the position information and a preset path of the robot.

Abstract: Some embodiments of the disclosure provides an intelligent modularized reconstruction system for a spacecraft based on analysis of a task text. In some examples, the intelligent modularized reconstruction system includes a modularized spacecraft component library, a modularized spacecraft component recommendation subsystem, a target spacecraft generation subsystem, and a three-dimensional simulation environment. In other examples, for a new spacecraft reconstruction task, the modularized spacecraft component recommendation subsystem recommends a type and a quantity of required modularized components from the modularized spacecraft component library for input task text. Each modularized component recommended by the modularized spacecraft component recommendation subsystem is used to generate three-dimensional model data of a target spacecraft by the target spacecraft generation subsystem. The three-dimensional simulation environment displays the generated three-dimensional model data of the target spacecraft.

Abstract: A voice recognition method includes obtaining a voice command inputted by a user for performing a voice control of a terminal device; determining an operation state of the terminal device; determining a target voice recognition model corresponding to the operation state; and recognizing the voice command using the target voice recognition model.
