Abstract: Disclosed are a rotating assembly, a supporting stand, and a photographing device. The rotating assembly includes a head adjusting structure including a first button, a first toothed disc, a second toothed disc, and a first elastic member. The first toothed disc is fixedly connected with a first head connector. The first elastic member is configured to enable teeth on the second toothed disc to mesh with teeth on the first toothed disc. The first button is configured to overcome an elastic force of the first elastic member under the action of an external force, so that the teeth on the second toothed disc are disengaged from the teeth on the first toothed disc. The angle of the first head connector fixedly connected to the first toothed disc is adjusted by using the first button, the first toothed disc, the second toothed disc, and the first elastic member.

Abstract: The present disclosure relates to robot technology, which provides a gait control method, device, and terminal device for a biped robot. The method includes: planning an initial position of an ankle joint of the biped robot and a rotation angle of a sole of the biped robot to rotate around one of a toe and a heel of the biped robot; planning a body pose of the biped robot; calculating a target position of the ankle joint based on the initial position of the ankle joint and the rotation angle of the sole; obtaining a joint angle of each of a plurality of joints of the biped robot by performing an operation on the body pose and the target position of the ankle joint utilizing an inverse kinematics algorithm; and adjusting a gait of the biped robot based on the joint angle of each of the joints.

Abstract: The present disclosure provides a robot motion path planning method, apparatus, and terminal device. The method includes planning a planned path for a robot in a current scene using an open motion planning library (OMPL) database, setting a shortest ideal path as an initial ideal path, calculating a new path between the planned path and the initial ideal path using a dichotomy method, determining whether the new path meets an obstacle avoidance requirement and a structural constraint of the robot in the current scene, making the new path as the new planned path if yes, otherwise determining the new path as a new ideal path, optimizing the planned path using the dichotomy method iteratively until an error between the planned path and the ideal path is within a preset range, and determining the planned path as a motion path of the robot, thereby improving the motion efficiency.
