The application discloses a multi-modal fusion-based embodied robot adaptive grasping system and method, relates to the embodied robot grasping technical field, and comprises the following steps: synchronously collecting depth point cloud and multi-band reflection spectrum data of a target object, and respectively constructing a geometric voxel model and a surface physical property matrix. Through cross-modal space alignment, the physical properties are accurately mapped to the geometric voxel to generate a fusion attribute voxel model. Based on the model, an optimal grasping area that simultaneously satisfies geometric stability, a high friction coefficient, a low thermal conductivity coefficient and a normal vector constraint is identified. According to the area information, the target pose and grasping force of the mechanical arm are calculated, and the grasping is controlled to be executed. The method realizes the collaborative utilization of the object geometry and physical properties, and makes the grasping action adaptive in the mechanical and thermal aspects.

The application provides a cover plate assembly, a composite cell and a battery pack. The cover plate assembly comprises a composite pole, an insulating piece, a first cover plate and a positive pole lug, and a second cover plate and a negative pole lug. The composite pole comprises a middle block and a first pole body and a second pole body protruding from the middle block, and the middle block is coated with the insulating piece. The first pole body penetrates through the first cover plate and the end of the first pole body is sleeved with the positive pole lug. The second pole body penetrates through the second cover plate and the end of the second pole body is sleeved with the negative pole lug. The positive pole lug is used for connecting the positive pole lug of the first cell, and the negative pole lug is used for connecting the negative pole lug of the second cell, so as to connect the two cells. The cover plate assembly can directly cover and connect the positive pole and the negative pole of the two cells, thereby realizing the direct connection of the two battery modules, reducing the setting of one or two groups of bus bars and circuit boards and the like, simplifying the battery structure, effectively reducing the space occupation of non-cell components, improving the energy density of the battery pack, and reducing the volume of the battery pack to facilitate the arrangement of the battery pack on various devices.

This application provides a method for upgrading bauxite after grinding with mother liquor, belonging to the field of mineral processing. The method includes: grinding a mixed slurry of bauxite to be upgraded and circulating mother liquor to obtain an alkaline slurry with fully liberated aluminum and gangue minerals; using the circulating mother liquor as both a separation and auxiliary medium throughout the process, performing mineral processing and upgrading on the alkaline slurry to separate iron and silicon impurities in the circulating mother liquor medium, obtaining a concentrate slurry and a tailings slurry; sending the concentrate slurry to an alumina leaching process; and separating the tailings slurry to obtain circulating mother liquor and tailings byproducts. This application, through systematic process reengineering and closed-loop media design, successfully develops a bauxite pretreatment method that can be deeply coupled and seamlessly integrated with the Bayer process main process, avoiding interference from external media, and achieving efficient impurity removal under fully liberated mineral conditions.
