    摘要： The present disclosure provides a robotic arm and a safety control method thereof. The robotic arm includes a plurality of joints and a plurality of acceleration sensors, and different the plurality of acceleration sensors are arranged on different the plurality of joints. The method includes: determining that a collision occurs in the robotic arm, and obtaining a first motion information of each joint through a corresponding acceleration sensor; determining a position information and a collision force information of the collision occurring based on the first motion information; and obtaining a safety control strategy based on the position information and the collision force information, and controlling the robotic arm to execute the safety control strategy. The present disclosure obtains the first motion information of the joint or joints in the region by means of the acceleration sensor(s) arranged on the joint(s), for determining the position information and collision force information of a collision occurring based on the first motion information, obtains a corresponding safety control strategy based on the position information and the collision force information, and controls the robotic arm to execute the safety control strategy, which is capable of realizing the collision detection of the robotic arm with a high degree of accuracy and a high degree of sensitivity.

    摘要： A method by which a mobile robot crosses a crosswalk, and the mobile robot are disclosed. The method by which a mobile robot crosses a crosswalk, according to an embodiment of the present invention, comprises steps in which the mobile robot: detects the crosswalk; detects the movement of at least one pedestrian within a predetermined range from the crosswalk; determines, on the basis of the detected movement of the at least one pedestrian, whether the traffic lights of the crosswalk indicate a walking signal; and crosses the crosswalk if it is determined that the traffic lights indicate the walking signal.
